Notes for the following versions of the Ping Identity Directory Server are available in this document:
Updating to the latest version of the Directory Server addresses the following critical issues from previous versions. Affected servers should be updated.
Fixed an issue that could allow users with locked accounts to change their own passwords using the password modify extended operation.
Fixed an issue where opening the backend database might fail with an IllegalStateException that references "exploded-index-background-deletes" when there are several backend exploded indexes.
The server can now detect an "out of file handles" situation on the operating system, and shut down to prevent running in an unreliable state.
Added a fail safe to the pending changes queue for the Changelog Backend that can detect and ignore recovered changes that do not need to be committed in order to prevent holding up other changes in the queue.
Disabled support for SSLv3 by default in the LDAP, HTTP, and JMX connection handlers, and for replication communication. The recently-discovered POODLE vulnerability could potentially allow a network attacker to determine the plaintext behind an SSLv3-encrypted session, which would effectively negate the primary benefit of the encryption.
SSLv3 was initially defined in 1996, but was supplanted by the release of the TLSv1 definition in 1999 (and subsequently by TLSv1.1 in 2006 and TLSv1.2 in 2008). These newer TLS protocols are not susceptible to the POODLE vulnerability, and the server has supported them (and preferred them over SSLv3) for many years. The act of disabling SSLv3 by default should not have any adverse effect on clients that support any of the newer TLS protocols. However, if there are any legacy client applications that attempt to communicate securely but do not support the newer TLS protocols, they should be updated to support the newer protocols. In the event that there are known clients that do not support any security protocol newer than SSLv3 and that cannot be immediately updated to support a newer protocol, SSLv3 support can be re-enabled using the newly-introduced allowed-insecure-tls-protocol global configuration property. However, since communication using SSLv3 can no longer be considered secure, it is strongly recommended that every effort be made to update all known clients still using SSLv3.
It is possible to use the server access log to identify LDAP clients that use SSLv3 to communicate with the server. Whenever an LDAP client establishes a secure connection to the server, or whenever a client uses the StartTLS extended operation to secure an existing plaintext connection, the server will generate a SECURITY-NEGOTIATION access log message. The "protocol" element of a SECURITY-NEGOTIATION access log message specifies the name of the security protocol that has been negotiated between the client and the server, and any SECURITY-NEGOTIATION messages with a protocol of "SSLv3" suggest that the associated client is vulnerable to the POODLE attack. In addition, if any connections are terminated for attempting to use the disallowed SSLv3 protocol, the access log message for that disconnect should include a message stating the reason for the termination.
Fixed a problem that could interfere with access to an exploded attribute index after performing an online index rebuild for that attribute.
Fix a bug in low level protocol buffer that could result in "uncaught exception" errors.
Improve server stability by disabling explicit garbage collections that were being caused by JMX connections.
Fix a bug in the LDAP Changelog where the changelog index manager could capture new changes for an attribute in one index after already hitting the end of another index. This created the possibility for changes to be missed when processing get-changelog-batch-requests at the same time that live traffic is happening.
Fix a bug that allows users with expired passwords to change attributes in their own entry other than password.
Address an issue where a directory server might resend duplicate changes when processing a GetChangelogBatch request in an environment that is under heavy load.
Update the Directory Server to apply access controls when processing the GetAuthorizationEntryRequestControl.
Fix a bug where Directory Servers could potentially miss some update messages in large topologies after a restart.
Following are notes for version 6.0.0.2 of the Directory Server.
The following issues have been resolved with this release of the Directory Server:
Updated support for the UNBOUNDID-MS-CHAP-V2 SASL mechanism to make it easier for an intermediate application to support delegating MS-CHAPv2 authentication to the Directory Server. This includes:
- The client SDK has been updated to make it easier to issue separate bind requests for each phase of the two-step authentication process. Previously, the API only exposed a single bind request that would perform both stages of the process.
- A new "proxied MS-CHAPv2 details" request control has been provided, which can be used to allow an intermediate application acting as an MS-CHAPv2 server to generate its own server challenge rather than obtaining one from the Directory Server.
- The client SDK has been updated to improve the javadoc documentation. A number of examples are included to demonstrate the process of using the SDK to authenticate with the UNBOUNDID-MS-CHAP-V2 mechanism. The README file has also been updated with instructions for enabling server-side support for the UNBOUNDID-MS-CHAP-V2 mechanism. Issue:DS-17002
Updated a couple of cases where filtered SCIM searches for groups with missing members were not returned. Issue:DS-17078 SF#:00003677,00003683
These issues were resolved with version 6.0.0.1 of the Directory Server:
Added a disabled-alert-type configuration property to the Alert Backend that can be used to suppress specific alert types from being added to the backend. Issue:DS-16906 SF#:3556
Fixed an issue during upgrade where a backend initialization error could occur for the Changelog Backend indicating "Environment is Read-Only." Issue:DS-16955 SF#:00003431,00003636
Critical: Fixed an issue that could allow users with locked accounts to change their own passwords using the password modify extended operation. Issue:DS-17074
Updated the commonly-used passwords dictionary to include many additional values, including known passwords used in several real-world breaches. Issue:DS-17007
Fixed an issue with the dictionary password validator that would cause it to stop processing the dictionary file once it encountered a blank line or a line containing only spaces. Any dictionary entries contained in the file after that point were incorrectly ignored. Issue:DS-17020
Fixed an issue that could impede the timely replication of subtree-delete requests contained in a transaction. Issue:DS-17008 SF#:3644
Fixed an issue where user resource limits defined on the authorization entry where not being enforced after a remote bind using the pass-through authentication plugin. Issue:DS-17046 SF#:3617
Fixed an issue where subtree view restrictions could register "replication replay failed" alerts when attempting to replay a subtree delete operation. Issue:DS-17048 SF#:3645
Fixed an exception that prevented editing a Replication Synchronization Provider in the PingData Administrative Console. Issue:DS-16982
Important upgrade considerations for version 6.0.0.0 of the Directory Server:
Note: The product names have been updated to reflect the UnboundID acquisition by Ping Identity. This is a naming and branding change only; the code base is the same as in prior releases and will continue to be maintained into the future.
If upgrading the server that was running an older version of the JDK, run the dsjavaproperties --initialize command after the software upgrade to compare the settings of the older JDK with requirements for the new server software. Apply any necessary changes to the upgraded server based on previous performance settings.
The 6.0 release makes these changes to supported platforms:
PBKDF2 is now the default encoding for root passwords. This only affects new installations.
In addition to changing the default password storage scheme for root users to PBKDF2, the default password storage scheme for regular users has been changed to salted 256-bit SHA-2.
HTTPS defaults to ON: servers now default to use HTTPS for console and API connections including the SCIM API. This may affect automation scripts and development environments where HTTPS has not been in use before.
Generated user passwords, for example those created by the server during a password reset sequence, are now created as pass-phrases instead of random character strings. This makes them them easier to type and remember. This change will not affect upgrades.
The /config directory file permissions have been changed so that they are only accessible by the server user.
Customers who choose to use the optional encryption algorithms provided by the third-party BouncyCastle library are encouraged to upgrade to BouncyCastle 1.54.
The Self Service Account Manager (SSAM) application is now included in the distribution image and may be optionally installed as desired.
Updated commons-beanutils from version 1.8.3 to 1.9.2 to improve security.
Updated Spring Boot artifact to v1.2.8 so transitive Spring library dependencies use v4.1.9.
Updated the HTTP/HTTPS connection handler to Jetty 9.2.15.v20160210.
These features were added for version 6.0.0.0 of the Directory Server:
Added a new control for very large result sets 'maximum-sort-size-limit-without-vlv-index,' which allows client applications to request that the server gracefully degrades to unsorted results in cases where sorting a very large result set would have caused a time-out.
Added LDAP support for applications that authenticate users with Yubikey one-time passwords. The extensions include the UNBOUNDID-YUBIKEY-OTP SASL handler configuration object, extended operations and command line tools for registering a user’s Yubikey device, deregistering, and supporting authentication using either the one-time password (OTP) only, or the OTP together with a static password. The server can be configured to use the public Yubico validation service, or a different validation service. The Yubikey FIDO U2F, OATH HOTP, and PGP modes are not supported.
Added new "generate TOTP shared secret" and "revoke TOTP shared secret" extended operations to make it easier for applications to enable TOTP authentication for users. While these operations are primarily intended to be invoked programmatically, a generate-totp-shared-secret tool can be used to invoke these operations from the command line.
A new transform-ldif tool is available to read an LDIF file and write an updated file with a number of changes applied. The transformations include:
A new load-ldap-schema-file tool is available for loading LDAP schemas while a server is active and on-line.
A new register-yubikey-otp-device tool is available for creating or changing associations between users and specific OTP devices.
The *rate performance testing tools now includes some additional sample rate pattern files: hockey stick, step-function, sine, triangle, sawtooth and square wave patterns.
The setup command now logs its input arguments, making it easier to confirm or duplicate a setup process. This changes the content of the log and may affect automated scripts that read these log files.
The config-diff tool, which makes it easy to compare and reconcile settings between server instances, now also supports the --pretty-print option which adds line breaks to the generated lists of dsconfig commands.
The manage-account tool has been enhanced significantly to make it easier to perform operations that affect large sets of user accounts including bulk lock-outs, parallel processing of updates, support for input filter criteria and DN lists. In particular, the manage-account tool now supports explicitly setting user accounts to the "locked-out" state. This is an improvement over earlier versions which required manipulation of operational attributes. See the command help for a complete list of the options and new sub-commands.
For easier consumption by third-party analysis tools, the Directory and Proxy Servers can now output JSON log formats. Similar support will be added to the Data Sync and Governance Brokers in a later release.
To help avoid issues when indexes near their index-entry-limit, the verify-indexes command now has the following two options:--listKeysNearestIndexEntryLimit, and --listKeysExceedingIndexEntryLimit. The Admin Guide includes a new section, "Monitoring Index Entry Limits", which explains how to set, track, and tune the server's Index Entry Limit values.
Monitor entries have been added for a number of related metrics, all of which can be set to trigger alarms:
The Pass-Through Authentication plugin has a new "allowLaxPassThroughAuthenticationPasswords" option that permits password changes that do not comply with the Directory Server's password policy. This facilitates integration in cases where the pass-through system has less-strict rules for new passwords.
For Java developers whose tools and workflows make use of Maven, the Server SDK jar has been deployed to Maven Central so that a developer can now add the Server SDK as a project dependency by adding a few lines to a project's pom.xml. Also, developers can now generate a Server SDK project that Maven-aware IDEs such as IntelliJ IDEA can package into an extension bundle with no special configuration needed. This benefit extends similarly to continuous integration systems such as Jenkins.
The dsconfig tool provides the ability to search for and quickly navigate to configuration objects and properties in which the name, synopsis, or description matches a provided pattern.
A new rotate-log tool and task have been added, which can be used to trigger rotation of one or more log files.
The Configuration API is now fully supported for all servers. In this release, the API was changed to match SCIM conventions for attribute naming, resource modeling, and the standard HTTP verbs. The UnboundID SCIM 2 SDK (available through GitHub) can now be used with the Configuration API.
All servers have an updated web Administrative Console, which includes:
The new Administrative Console can also be deployed to independent application servers instead of being co-hosted by the servers. This simplifies deployment models and increases separation between data and application layers.
To assist with situations where a very large number of changes may cause disk, memory, and server start time to increase unexpectedly, alerting and gauge features have been added to the Recent Changes Database.
Servers can now trigger events whenever log file rotation occurs. This includes "copy on rotate" and "summarize on rotate" listeners, as well as Server SDK support for creating custom log file rotation listeners.
It is now possible to create, change, and remove root user accounts across the topology using the dsconfig tool and Administrative Console.
Made a number of improvements to way the server handles the encryption settings database:
Updated the search-logs tool to support JSON formatted logs.
The dsreplication initialize command now ignores the adminUID and adminPassword property values in the tools.properties file, as these values may not necessarily be correct for the new server being added to the replication topology. The command now always prompts for the administrative credentials.
These were known issues at the time of the release of version 6.0.0.0 of the Directory Server:
When deploying the Administrative Console in Tomcat 8, and accessing the Administrative Console application using Tomcat's Web Application Manager, some browsers (including Safari and Firefox) will generate a path URL that encodes the dash in ubid-console. This results in a path such as http://localhost:8888/ubid%2Dconsole/, which causes session management errors. To workaround this issue, copy and paste the generated link into a browser, and replace the encoded dash with a dash (-) character.
The PermSize and MaxPermSize JVM properties are no longer supported in JDK 8, and will safely be ignored. These properties can be removed by modifying the config/java.properties file and running "bin/dsjavaproperties" while the server is offline.
Security criteria for root passwords with the default configuration will be increased in a future release. This might affect automated installation scripts that currently use less secure passwords. This will not affect existing root accounts.
The dsconfig tool and the Administrative Console enables creating and managing new Root DN users in this release. However, there is a limitation with changing the password of the currently logged in administrator. The ldappasswordmodify command can be used to change the administrator's password by providing the current and new password.
For version 5.2.0.1 to pre-6.0.0.0 servers configured to use the IBM version of Java, an extraneous ${INSTANCE_ROOT} directory is created under the server root. This is fixed on a fresh install of 6.0.0.0, but if updating to 6.0.0.0, this directory still exists and can be deleted before or after the update.
These issues were resolved with version 6.0.0.0 of the Directory Server:
Fixed an issue in which the server may fail to identify matching entries for an OR JSON object filter that targets an attribute for which at least one JSON field index is defined, but where at least one of the OR filter components is unindexed. Issue:DS-16589
Updated the password modify extended operation to enable a user to provide an expired password, as long as the user has at least one available grace login. Issue:DS-16289
Updated the changelog backend to better deal with the case in which it encounters information about an orphaned operation in its pending changes map. Issue:DS-15993
Added a warning during startup for any invalid group entries that are encountered and cannot be used. Issue:DS-13976 SF#:2934
Updated command-line tools based on the LDAP SDK tool APIs to add the following features:
Updated the verify-index tool to improve performance and reduce disk utilization. Issue:DS-12310
Added a passphrase password generator that concatenates randomly-selected words from a dictionary file to construct a password that can be both secure and easy to remember. Issue:DS-14424
Updated the offline mode of the rebuild-index tool to improve performance and reduce disk utilization. Issue:DS-12309
Added a --prettyPrint option to the config-diff tool to make the output more human-readable. Issue:DS-14694
Improved memory utilization when processing entries with very large attributes, to prevent possible data retention in memory. Issue:DS-14878 SF#:00003169
Added a new global configuration property, unrecoverable-database-error-mode, which enables configuration of an action to take when an unrecoverable database error occurs. Issue:DS-14796
Fixed an issue with the dsjavaproperties tool where java properties for PermSize and MaxPermSize could be added when using JDK 8, which no longer supports these options. Issue:DS-14857 SF#:3187
Updated the bcrypt, crypt, PBKDF2 and scrypt password storage schemes so they can be used to create new instances. Issue:DS-14923
Fixed a formatting issue in ldap-diff which could result in multiple progress messages being printed on the same line. Issue:DS-14986 SF#:3205
Updated the Apache commons collections library to address the security vulnerability described by CVE 2015-4852. Issue:DS-14430 SF#:00003216
Fixed a case where attribute syntax configuration changes would not apply to undefined attributes, which rely on default attribute types. Issue:DS-14979
Updated the server to use the latest 6.4.25 release of Berkeley DB Java Edition. Issue:DS-14996
Collect-support-data tool now captures Kerberos config and log information. Issue:DS-13823
Updated the server's support for the Twilio Messaging Service so that it uses the newer "Messages" API when sending SMS messages instead of the older "SMS" API. The older API has been deprecated, and Twilio now imposes a 120-character limit for messages sent via that API. The messages API allows the server to take advantage of the full 160 characters per SMS message. Issue:DS-14749
The replication target of the Directory Server now correctly handles the connection being lost during initialization. Issue:DS-14690
Improved the logic the server uses when leveraging indexes to identify the set of candidate entries that are expected to match the search criteria. Also, dramatically improved the information about index usage that the server provides when issuing a search that requests the special debugsearchindex attribute, or that includes the matching entry count request control. Issue:DS-14820 SF#:00003178
Updated the pass-through authentication plugin to allow replacing passwords for migration from legacy directory products. Issues:DS-15007,DS-15083 SF#:00003198
Updated the default set of global ACIs to permit requests that include the simple paged results control. Issue:DS-15082
Server SDK extensions are now built with a Java source version of 1.7 by default. Issue:DS-15015
Improved the message used to indicate when the replication server startup minimum replication backlog processing completes. The message now states that the calculation was done when the server was started, and any missing local replicas that were unavailable for the calculation are listed. Issue:DS-15079 SF#:3220
Critical: Fixed an issue where opening the backend database might fail with an IllegalStateException that references "exploded-index-background-deletes" when there are several backend exploded indexes. Issue:DS-15094
Improved the locking strategy for multi-update requests to better accommodate delete and add requests for the same entry. This also enables graceful failures for bad requests, instead of lock timeouts. Issue:DS-15132 SF#:3248
Updated the manage-account tool to display labels for recently added password policy extended operation types. Issue:DS-15159 SF#:00003262
Added a maximum-sort-size-limit-without-vlv-index property to the client connection policy configuration. If this property is given a nonzero value, the server will not attempt to sort a result set if the number of candidate entries is greater than this number, unless it can do so using a VLV index. If the server refuses to sort a result set because of this setting, then it will either reject the search (if the server-side sort control is marked critical), or it will return the results unsorted (if the server-side sort control is not critical). Issue:DS-14855 SF#:2799
Changed interactive setup default value for HTTPS enablement. Issue:DS-15221
Changed interactive setup default value for entry cache priming. Issue:DS-15222
Added new options to the matching entry count request control to allow the client to better control the balance between how quickly the server obtains the matching entry count estimate and how accurate that estimate is. Issue:DS-15227 SF#:3178
Updated the server to reject baseObject searches that request the debugsearchindex attribute. Issue:DS-15284
Added support for authenticating with one-time passwords generated by YubiKey devices. The server may be configured to require static passwords in conjunction with YubiKey one-time passwords as a form of two-factor authentication, or it may be configured so that a one-time password alone is sufficient for authentication. Issue:DS-7017
Updated the initial server configuration to improve security and usability. These changes apply only to new installations and will not be applied when updating an existing installation. Changes include:
Updated the default file permissions for new installations on UNIX-based systems. Files and directories included in the zip file will be only be accessible to their owner (the user that unzipped the file) by default.
Newly-created files and directories will also be assigned permissions that allow them to be accessed only by the account used to run the server. Existing configuration options for setting file permissions (the log-file-permissions and db-directory-permissions properties) will continue to behave as before. The new config/server.umask file will control the default permissions for all other newly-created files and directories. Issues:DS-13571,DS-13860,DS-7505 SF#:2703
Fixed a bug that could cause the same filter index to be evaluated multiple times when processing a search operation. Issue:DS-15366
Updated the global ACIs that ship with the server to use a separate ACI for each control or extended request to allow by default, rather than grouping all desired controls together in one ACI and all desired extended requests together in a second ACI. This change will only be reflected in new installations, and not when updating an existing deployment. Issue:DS-15417
Increased the default cache size set by the installer for JVM heaps smaller than 8GB. Issue:DS-15415
Addressed an issue where dsconfig incorrectly allowed certain configuration objects to be deleted. Issue:DS-15400
Updated the changelog backend to report progress and summary information when exporting to LDIF or importing from LDIF. Also fixed a problem that could cause valid entries from being imported because of a mistaken schema violation. Issue:DS-15471
Updated mirror virtual attribute provider implementation to read values from additional entries when the source entry dn attribute has more than one value. Issue:DS-15286
Provided a graphical tool, watch-entry, that is intended to demonstrate replication or synchronization latency by watching an LDAP entry for changes. If the entry changes, then the background of modified attributes will temporarily be red. Attributes can also be directly modified as well. Issue:DS-15437
Updated interactive setup to display default values, and improved the overall layout and appearance. Issues:DS-15361,DS-15363,DS-15434
Added more logging information when initializing web application and servlet extensions in case an extension causes conflicts or delays. Issue:DS-15466
Updated setup to encode the root password with the PBKDF2 password storage scheme instead of SSHA512. Issue:DS-15521
Fixed a defect where removing an objectClass value could result in an entry that violates the schema, we will now ensure that the entire entry is valid whenever adding or removing objectClasses. Issue:DS-15516 SF#:3234
Increase the minimum memory requirements for the server process from 256MB to 384MB to accommodate the Administrative Console. Issue:DS-15571
Added a load-ldap-schema-file tool that will allow the server to recognize a new schema file, or an updated version of an existing schema file, and make the definitions immediately available without needing to restart the server. Issue:DS-15576
Updater tool will increase PermSize and MaxPermSize parameters to recommended value to prevent Java JVM pauses. Issue:DS-15522 SF#:00003324
Fixed an error that could occur during upgrade when the configuration can not be loaded due to missing custom schema. Issue:DS-15592 SF#:3340
Updated the Groovy Scripting Language version to 2.4.6. Issue:DS-15621
Added support for an UNBOUNDID-EXTERNALLY-PROCESSED-AUTHENTICATION SASL mechanism that indicates that an application attempted to verify the identity of a user whose account is stored in the server but that used a form of authentication that is external to the server (for example, via social login). The server will not alter the authentication state of the underlying connection, but may veto a successful external authentication if the user's account is not in a usable state (for example, the account is locked or disabled, or the password is expired), or it may update password policy state for the user to reflect the authentication attempt (for example, updating the last login time and IP address for a successful authentication, or recording the failed attempt and potentially locking the account for an unsuccessful authentication). Issue:DS-15559
Replaced the tabs in parallel-update log messages for failure with spaces and made the log message timestamps consistent with other logs. Issue:DS-15724
Improved visibility of the use of index keys near or in excess of the index entry limit. These changes include:
Changed the dsjavaproperties command so that its --initialize operation now carries over properties that are tool-independent from an existing java.properties file, such as the default java home and the tuning parameters. Issue:DS-15578
Added the default JVM argument "-XX:UseCMSInitiatingOccupancyOnly" to decrease server pauses by forcing the JVM to respect the CMSInitiatingOccupancyFraction. Issue:DS-15578
Updated the verify-index tool to add a "--listIndexKeysNearestIndexEntryLimit" argument to obtain information about the keys whose ID lists are closest to (but have not yet exceeded) the index entry limit, including the number of matching entries and how close they are to reaching the limit. Issue:DS-247
Improved server performance by reducing the cost of determining the transaction settings for interacting with the backend database. Issue:DS-15768
Updated the server SDK generated documentation to use the new logo and new icon. Issue:DS-15691
Added memory tracking to the FIFO Entry Cache. The memory usage of the FIFO Entry Cache is about 10% less than reported, but is not likely to be higher than reported. Issue:DS-15794
The Data Services Markup Language (DSML) client and gateway components have been discontinued and are no longer available. Issue:DS-15753
Updated the unique attribute plugin so that the filter property applies to conflict searches, and matches entries being added or modified. Issue:DS-15791
Changed default number of HTTP request handlers from 2 times to 4 times the number of processors available to the Java virtual machine to improve performance. For example, the default has increased from 128 to 256 on a dual-socket, 8-core x64 CPU-based system with hyper-threading enabled. Issue:DS-15773
Added the ssl-cert-nickname property to the HTTP Connection Handler. If multiple public-private key pairs are in a JKS keystore, the LDAP Connection Handler enables choosing a specific certificate alias with the ssl-cert-nickname property. The HTTP Connection Handler for HTTPS connections now has the same option for parity. Issue:DS-15477
Updated the FIFO Entry Cache's max-memory-percent property to specify the maximum percentage of JVM memory the cache can use. Previously the property specified the maximum percentage of memory that must be consumed in the JVM by the application overall before the cache begins to shrink. Issue:DS-14863
The configuration framework now trims leading and trailing spaces from distinguished names. Issues:DS-13870,DS-13940
Added a new rotate-log tool to request the rotation of one or more log files. Issue:DS-10464
Improved the error messages produced by the manage-extensions tool when attempting to install invalid extensions. Issue:DS-15412
Improved the error messages and examples for create-rc-script and create-systemd-script by explicitly suggesting the use of sudo so that the scripts can modify protected files. Issue:DS-15178
Rewrote the manage-account tool to provide many new features:
Updated the isMemberOf virtual attribute implementation so that it preserves the case of the RDN attribute and value in the group DNs. Issue:DS-15968
The former suite of Administrative Console applications, each of which were tied to a particular product (for example the dsconsole.war for the Directory Server) are no longer available, and have been superceded by a new version of the Administrative Console capable of managing any server product. You can choose to access the Administrative Console by hosting it within a server, or by deploying it in an external servlet container. For the former, enable an HTTP Connection Handler and add the Administrative Console Web Application Extension to the handler. For the latter, download and unzip the management-console-[version].zip file, and install the ubid-console.war file according to your container's instructions. Issue:DS-15088
Root DN User configuration entries can now be fully managed through the configuration management interfaces such as dsconfig and the Administrative Console. Issue:DS-15422
Added support for log file rotation listeners, which allow for custom processing whenever a log file is rotated out of service so that the server will no longer write to it. A copy listener (which will copy the rotated log file to an alternate location, optionally compressing it in the process), and a summarize listener (which will invoke the summarize-access-log tool on the rotated log file) are included. The Server SDK also includes an API for creating custom log file rotation listeners. Issue:DS-4235
Improved the log message for memory pools with an undefined maximum size when priming a server. Issue:DS-14658
Improved the warnings given when the maximum memory that all server components can consume is greater than the available memory in the JVM. Issue:DS-15920
Replaced the scramble-ldif tool with a more powerful transform-ldif tool with support for a number of additional transformation types. The new transform-ldif tool is backward compatible with the former scramble-ldif tool, and the scramble-ldif shell script and batch file are still included with the server to ensure compatibility with scripts that depend on that tool. Issue:DS-15108
Updated the password policy state extended operation and the manage-account tool to provide a way to obtain a list of the SASL mechanisms and OTP delivery mechanisms that are available to a user, to determine whether a user has a TOTP shared secret, and to retrieve and manipulate the set of public IDs for the YubiKey OTP devices registered for a user. Issue:DS-16104
Improved the collect-support-data tool to include information provided by systemd on platforms that support it. Issue:DS-13401
Improved the error messages for create-rc-script and create-systemd-script when the directory in which the script will be created does not exist. Issue:DS-15337
Improved the dsconfig tool to validate that there is only one enabled entry cache per entry cache level. Issue:DS-13478
If a replicated operation has failed multiple times as a result of database lock conflicts resulting from interactions with other operations, the server will now acquire an exclusive lock before making a final attempt at processing that operation to ensure that no other operations will be allowed to conflict with it. Issue:DS-16149 SF#:3482
Added support for a "generate TOTP shared secret" extended operation that allows a client to request that the server generate a shared secret for a specified user that will be stored in the user's entry and returned to the client. That shared secret can be used to generate time-based one-time passwords for use in the course of authenticating to the server through the UNBOUNDID-TOTP SASL mechanism. A "revoke TOTP shared secret" extended operation was also added to allow a shared secret to be eliminated if it is no longer needed or may have been compromised. The password policy state extended operation and the manage-account command-line tool have also been updated to provide support for manipulating the set of TOTP shared secrets for a user. Issue:DS-15349
Updated replication hostname checking with support for certificate alternative subject names and dnsname extensions checking. Issue:DS-13417 SF#:00002659
Added the server's process ID to the output of the status tool. Issue:DS-10312
Added support for JSON-formatted access and error log messages. Issue:DS-14919
Added a monitor entry for each Server SDK extension. Issue:DS-14548
The Configuration API now returns unquoted, native Javascript values for integer, real number, and boolean properties. Duration and size property values, for example '1 w' or '100 G', continue to be represented as Javascript string types. Issue:DS-15175
Added the ability to create local constants in LDIF template files using the new 'local' keyword. Issue:DS-14213
Updated the server to allow users with expired passwords to authenticate with SASL mechanisms that do not involve passwords. Issue:DS-15789
Added r) option in dsconfig interactive mode which shows how to preform the pending operation through the configuration REST API. Added --rest option to config-diff which changes the output from dsconfig command line arguments to configuration REST API arguments. Issue:DS-15792
Addressed a few issues in config-diff. In some situations, config-diff would not generate commands in an order that respected all dependencies. This has been fixed. Most expected warnings are now excluded by default but can be included in the output with the --includeAllWarnings option. The --sourceBindPasswordFile and --targetBindPassword are now applied in conjunction with the --targetConfigGroup and --sourceConfigGroup options. Issues:DS-10466,DS-10765,DS-14479,DS-15318,DS-16154
Added support for setting the request header size in the Jetty http configuration server properties. Issue:DS-12191 SF#:00002580
Updated the restore command so that it can no longer be used to restore a backup of the config backend. The command now points the administrator for safer ways to revert configuration changes, including using config-diff. Issue:DS-14704
Updated the sanitize-log tool to add support for JSON-formatted access and error log files. Issue:DS-16224
Added the ability to search for configuration objects and their properties by name with the dsconfig tool. Issue:DS-979
Added a --dry-run option to dsconfig, which can be used in batch mode to validate the configuration changes in a batch file without applying them. Issue:DS-10946
Fixed an issue that prevented the server from using the allowed-unauthenticated-request-criteria property to indicate which extended operations would be allowed on an unauthenticated connection when reject-unauthenticated-requests was set to true. Issue:DS-16267
Fixed an issue in which a password modify extended request that included the target user's current password could be seen as an administrative reset rather than a self change and might put the user's account in a "must change password" state if the user's password policy has force-change-on-reset set to true. Issue:DS-16266
Updated the local DB backend to provide an option to use a single-writer lock to avoid database lock conflicts between operations by ensuring that only a single write operation may be in progress at any time.
By default, write operations do not acquire the single-writer lock and are fully concurrent as long as none of those operations result in database lock conflicts. In the event that a lock conflict does arise between two or more operations (which should be a very rare occurrence in most environments), the server will retry each of those operations one or more times. With the changes included in this update, the server will now also acquire a single-writer lock to ensure that it only processes one of those conflicting operations at at time to reduce the likelihood of a further conflict.
In environments with a very large number of database lock conflicts, it may be desirable to configure the server to acquire the single-writer lock even on the first attempt of each write operation. This can be accomplished by setting single-writer-lock-behavior property to always-acquire in the backend configuration. While this can limit the overall write performance that the server can achieve, the server should still be able to process thousands of write operations per second, which is more than enough for most deployments.
The use of the single-writer lock does not have any effect on the concurrency of read operations. The server may still process any number of read operations simultaneously, even when the single-writer lock is used to ensure that only one write operation may be processed at any time. Issue:DS-16150
Added the ability to define an ACI to grant regular users access to the debugsearchindex operational attribute. This attribute can be used to obtain detailed information about the server's use of indexes in the course of processing a search request, and it was previously accessible only to users with either the bypass-acl or bypass-read-acl privilege.
To grant this access, you will need to permit access to both the debugsearchindex operational attribute, and to the cn=debugsearch portion of the DIT. For example, if you have a group with DN "cn=debugsearchindex Users,ou=Groups,dc=example,dc=com" and you want to grant the members of that group the ability to use the debugsearchindex feature, you can use the following command to add an appropriate global ACI to permit that access:
dsconfig set-access-control-handler-prop --add "global-aci:(targetattr=\"debugsearchindex\")(target=\"ldap:///cn=debugsearch\")(version 3.0; acl \"Allow members of the 'debugsearchindex Users group to request the debugsearchindex operational attribute \"; allow (read,search,compare) groupdn=\"ldap:///cn=debugsearchindex Users,ou=Groups,dc=example,dc=com\";)"
In addition, the server now allows the debugsearchindex attribute to be requested in a case-insensitive manner. Previously, the server would only recognize debugsearchindex in all lowercase. It can now be requested in mixed case, like debugSearchIndex. Issue:DS-15672
Fixed an issue that could prevent password reset tokens from being used on locked accounts when the server was configured to permit such changes. Issue:DS-16282
Updated the pass-through authentication plugin to suppress the "force change on reset" behavior if the user's local password is replaced with a password that was accepted by a backend server. Issue:DS-15096
Fixed a null-pointer exception error that occurred when performing a bounded range search on an unindexed attribute. Issue:DS-16348 SF#:3513
The backend is no longer locked with an exclusive lock when renaming an entry due to an add conflict during replication. Issue:DS-15470 SF#:00003320
CollectSupportData collects to gc-with-context all log messages for all stop-the-world GC events longer than one second, along with the two previous log messages. Issue:DS-16444
Updated the pass-through authentication plugin to make it possible to search for the appropriate user entry in the external server using a filter constructed from attributes in the local server's copy of the user entry. This makes it possible to use pass-through authentication in cases where the user's entry has a different DN in the external server than in the local server, and where the DN for the external server cannot be constructed from the information contained in the local copy of the user entry. Issue:DS-16489
Fixed an issue with JSON field indexing that could occur if the same field value appeared in multiple attribute values in the same entry, when at least one of those field values was removed or changed and at least one remained the same. Issue:DS-16337
Fixed an issue that prevented the deletion of disabled debug loggers. Issue:DS-15622
Updated the Local DB Backend to detect the database being only partially initialized via a "dsreplication initialize" command. If the backend is started with a partially initialized environment, then the incomplete database files will be deleted, and an alarm will be raised to signal to the administrator that the backend must be reinitialized. Issue:DS-11927
Fixed an issue where update verification fails to catch a problematic update that causes the server to not start. Issue:DS-16113
Improved an error message about a possible database recovery operation that may be triggered after a database restore from a online backup or during replication binary initialization. In rare cases, the database recovery may cause a delay while opening the database. Issue:DS-16137
Fixed an issue with the summarize-access-log tool where it would appear to hang due to slow processing of large complex filters. Issue:DS-15009
These features were added for version 5.2.0.0 of the Directory Server:
Improvements to Data Store’s Native JSON Attribute Support
The previous release of the Data Store included native support for compactly storing JSON objects in LDAP attributes, and for evaluating filters to match on fields inside those JSON objects. This release adds support for enforcing constraints on the fields that may be included in JSON objects, for indexing field values for improved search performance and flexibility, and for tokenizing commonly-used string values to further reduce the data footprint.
New Pasword Validators
The Data Store now includes the Haystacks Password Validator, based on the Gibson Research Corporation Password Haystacks concept, and the Commonly-Used Passwords Dictionary Validator, which ensures that a proposed password is not one of 10,000 commonly used passwords.
Can Request an entryUUID rdn Value when Adding an Entry
When adding a new entry to the server, the client can now request that the server-generated entryUUID be used as the RDN attribute for the entry. This improves privacy by ensuring that the entry DN will not include any personally-identifying information, and it is a convenience for application developers by eliminating the potential need for modify DN operations.
Implemented a Virtual Attribute Provider
Added an Identify References virtual attribute provider. These virtual attributes will have values that are the DNs of entries that contain a specified attribute with a value equal to the DN of the entry containing the virtual attribute. For example, this could be used to create a virtual 'directReports' attribute whose values are the DNs of the entries that list the target user as their manager.
Self-Service Account Manager (SSAM)
SSAM is a web application that provides a user interface for performing common account registration, attribute update and password change tasks against the Data Store, with optional integration with PingFederate and PingAccess products.
These were known issues at the time of the release of version 5.2.0.0 of the Directory Server:
When deploying a .war file through the Web Application HTTP Servlet Extension, dependencies bundled in the file may conflict with the server's own dependencies if the server version differs from the version in the .war file. This may cause the Web Application HTTP Servlet Extension or the server itself to not start correctly. For reference, all server dependencies are available in
These issues were resolved with version 5.2.0.0 of the Directory Server:
The setup tool has been updated to use HTTPS for initial configuration. Unsecure HTTP can be enabled post-setup, or by using non-interactive setup. Issue:DS-12182
Addressed cases where some messages may be suppressed in logs and alerts. Issue:DS-12287
Updated the server to automatically monitor and report the length of time each operation spends waiting in the work queue before a worker thread can begin to process it. Issue:DS-12218
Updated the local DB backend so that changes to the db-checkpointer-wakeup-interval property no longer require a restart to take effect, and to expose new monitor attributes with useful information about the processing performed by the database cleaner. Issue:DS-12263
Added a configuration option to enable a wait period before removing a 'server unavailable' alert after a garbage collection task is performed. This allows sub-systems like replication to restart before the server becomes available again. For the Periodic GC Plugin, this option is 'delay-post-gc.' For a Forced GC Task entry, the attribute is named 'ds-task-delay-post-gc.' Both options take a value in milliseconds, and have a default value equivalent to 20 seconds. Issue:DS-12318
Updated the Configuration API output where properties and their values are listed to include those that are undefined. Issue:DS-12123
Changed the default password policy behavior to prevent users from changing their passwords to their current password value. This logic will apply regardless of password history settings. Issue:DS-12313 SF#:2546
Added the 'listKeysExceedingIndexEntryLimit' argument to the verify-index tool, which enables listing the keys for indexes that have exceeded their index entry limits. Issue:DS-3186
Updated UnboundID work queue processing to log expensive work queue operations and diagnostic thread stack traces when a queue backlog alarm is raised. Issue:DS-12319
Added support for running on Oracle Java 8 and OpenJDK 8 platforms. Issue:DS-12483
Fixed an issue that generated the following error message, but did not impact the current operation: "An unexpected error occurred while notifying a change notification listener of a modify operation: RuntimeException: The specified condition must be true. The error occurred at com.unboundid.directory.server.types.AuthenticationInfo.replaceUserEntries." Issue:DS-12443
Added features to allow clients to better determine the set of requirements that the server will impose for user passwords. The get password quality requirements extended operation can be used to retrieve information about the requirements before an attempted password change. Those requirements can be conveyed to the end user, and can potentially be used to enable some types of client-side validation to identify problems with a password before it is sent to the server. The password validation details request control can be included in an add request, a modify request, or a password modify extended request to identify which specific validation requirements may not have been met by the password provided in the request.
Password validators can be configured with user-friendly messages that better describe the constraints that the validator will impose for passwords, and that the validator should return if a proposed password does not satisfy those constraints. The server will generate these messages if they are not provided in the configuration. Issues:DS-12107,DS-12137
The Configuration API has been updated to support filtering, sorting, and paging for object list operations. See the Administration guide for usage. Issue:DS-12245
Added the ability to reset user passwords with a single-use, time-limited token that is delivered to the end user through some out-of-band mechanism like SMS or email. After determining the identity of the user for whom the password reset token should be generated, an application can use the new "deliver password reset token" extended operation to cause the server to create and deliver the token to the user. This token can then be provided to the "password modify" extended operation in lieu of the user's current password in order to allow that user to select a new password. Password reset tokens can optionally permit users to reset their passwords even if their account is not usable (for example, because their account is locked or their password is expired). Issue:DS-8739
Fixed an issue where configuring numeric IPv4 address filtering by connection criteria in a log publisher performed unnecessary reverse hostname lookups. Issue:DS-12610 SF#:00002632
Updated the notification destination cn=monitor entry (objectclass of ds-notification-destination-monitor-entry) to include an attribute, ds-notification-age-of-next-pending-change-seconds, which tracks how out-of-date the destination is in seconds. Values are only maintained on the master server for that domain (ds-notification-master=true). A value of 0 on the master server for that domain indicates that the destination is up-to-date. This attribute can be used in a gauge to generate alarms if a destination gets too far behind. Issue:DS-12618 SF#:2597
Added logging of all HTTP requests disallowed due to CORS. This should make it easier to debug HTTP 403/Forbidden errors. Issue:DS-12496
The server can now detect an "out of file handles" situation on the operating system, and shut down to prevent running in an unreliable state. Issue:DS-12579 SF#:2655
Update the Detailed HTTP Operation Log Publisher to log the correct return code (404 NOT FOUND) when a request is not handled by defined endpoints. Issue:DS-12576
Added support for a JSON object attribute syntax, which can be used for attribute types whose values are JSON objects. The syntax requires that each value of this type is a valid JSON object. Two matching rules have also been added for use in conjunction with the JSON object syntax: jsonObjectExactMatch and jsonObjectFilterExtensibleMatch.
The jsonObjectExactMatch equality matching rule is used in evaluating equality filters in search operations, as well as for matching performed against JSON object attributes for add, compare, and modify operations. It determines whether two values are logically-equivalent JSON objects. The field names used in both objects must match exactly (although fields may appear in different orders). The values of each field must have the same data types. String values will be compared in a case-insensitive manner. The order of elements in arrays will be considered significant.
The jsonObjectFilterExtensibleMatch matching rule can perform more powerful matching against JSON objects. The assertion values for these extensible matching filters should be JSON objects that express the constraints for the matching. These JSON object filters are described in detail in the Javadoc documentation (available in the Commercial Edition of the UnboundID LDAP SDK for Java) for the com.unboundid.ldap.sdk.unboundidds.json.JSONObjectFilter class and its subclasses. Although the LDAP SDK can facilitate searches with this matching rule, these searches can be issued through any LDAP client API that supports extensible matching.
Indexing is supported only for the jsonObjectExactMatch matching rule. If possible, non-baseObject searches that use the jsonObjectFilterExtensibleMatch matching rule should be wrapped in an LDAP AND filter that also contains one or more indexed components so that the search can be processed more efficiently. Issue:DS-12138
Fixed an issue where changes to SMTP External Server configurations did not take effect until after a server restart. Issue:DS-12285
Added support for three new extended operations for interacting with single-use tokens:
Fixed an issue where the Data Store parsed the last login time value using the wrong time zone. The incorrect time affected password policy decisions and was delivered in the response to a password policy state extended request. Issue:DS-12943
Updated the server to avoid the use of the server-side sort and virtual list view request controls in search requests that span multiple subtree views or multiple entry-balanced backend sets. If the server cannot honor a non-critical server-side sort or virtual list view control, then it will process the search operation as if the control had not been included in the request. If the server cannot honor a critical server-side sort or virtual list view control, then it will return an error result to the client. Issues:DS-12560,DS-12561
Improved server locking used by dsconfig in offline batch mode, so that the server lock is held for the entire batch duration, instead of for each invocation. Also, reduced the probability of contention for file locks used by server tools to determine the server status. Issue:DS-12969 SF#:2717
Fixed a rare condition that might cause the logger rotation and retention thread to exit under heavy file system load or a network file system outage. Issue:DS-12880
MakeLDIF templates now have the ability to escape special characters curly braces, angle brackets, and square brackets using a backslash. See config/MakeLDIF/examples-of-all-tags.template for further examples. Issue:DS-12798
Added the ability to configure the Globally-Unique Attribute and Unique Attribute plugins with a filter to limit attribute uniqueness checking to a subset of matching entries. Issue:DS-9842
Fixed the Local DB Backend configuration help text for deadlock-retry-limit, which incorrectly stated that a value of zero would result in unlimited retry attempts. That value actually results in no retry attempts. Issue:DS-12909
JDBC external servers now give precedence to settings in the jdbc-driver-url property, over other dsconfig JDBC Managed Object settings for host-name, port, and database-name. The jdbc-driver-url property setting can be used instead of the other JDBC Managed Object settings. Issue:DS-12700
Added a gauge to monitor the number of available file descriptors. This Available File Descriptors gauge can detect if a server if running out of file descriptors and degrade the server appropriately. Issue:DS-12727
Addressed an issue where data definition language (DDL) log field mappings for the JDBC error log were not previously documented. Issue:DS-13163
Fixed an issue where debug logging at a fine-level could consume large amounts of memory. Issue:DS-13124
Updated the server to use the latest 6.3.8 release of the Berkeley DB Java Edition. Issue:DS-13206
Reduced the memory overhead of debug logging in high throughput environments by sharing logging buffers across multiple threads. Issue:DS-10010
Improved the server shutdown time in situations when there is a database cleaner backlog. This also ensures a faster start up time since database recovery isn't needed. Issue:DS-13207
Updated the local DB backend to always try to keep exploded indexes in the database cache, and to always load exploded indexes into the cache on startup if database preloading is enabled, even if the database containing non-exploded index data for the associated index is configured with a lesser cache mode or preload configuration. Because reading from exploded indexes requires much more database interaction than non-exploded indexes, this can dramatically improve the performance of exploded index accesses for deployments in which it is not possible to fully cache all data in the backend. Issue:DS-13182
Updated the server's JVM arguments to always log garbage collection information to a rotating set of log files stored within logs/jvm/gc.log.N. The file system usage is limited to 300MB. If the server had previously been configured with VERBOSE_GC, then garbage collection logging information will no longer be logged to logs/server.out. Issue:DS-11522
The following UnboundID product names have changed: - Identity Data Store to Data Store - Identity Proxy to Proxy Server - Identity Data Sync Server to Data Sync Server - Identity Broker to Data Broker Issue:DS-12799
Custom HTTP loggers are no longer permitted to modify the requests and responsesbeing logged. Calling a forbidden method will result in a subclass of UnsupportedOperationException. For requests, the forbidden methods are authenticate, getReader, login, logout and setCharacterEncoding. For responses, the forbidden methods are addCookie, addHeader, addIntHeader, flushBuffer, getOutputStream, getWriter, reset, sendError, sendRedirect, setBufferSize, setCharacterEncoding, setContentLength, setContentType, setHeader, setIntHeader, setLocale and setStatus. Issue:DS-10283
Fixed a bug where using the advanced arguments of some tools would result in changing the saved complexity settings for the dsconfig tool. Issue:DS-12897
Fixed a defect where a deny ACI with target attrs would prevent Modify DN operations from succeeding, even when the target attrs did not include any RDN attrs. Issue:DS-13453 SF#:2807
Fixed an edge case problem in which a password change could result in the previous password not being included in the password history. Issue:DS-13481 SF#:2813
Updated the server to use the latest 6.3.9 release of the Berkeley DB Java Edition. Issue:DS-13426
Updated the installer to increase the maximum suggested JVM size on Linux systems with at least 48 GB of RAM. Issue:DS-12982
Added a new search-logs tool. Similar to the command line tool 'grep,' this tool searches across log files to extract lines matching the provided pattern(s). The search-logs tool can handle multi-line log messages, extract log messages within a given time range, and include rotated log files. Issue:DS-3095
Fixed an issue that could cause the server to overlook attribute options in an indexed search filter. Issue:DS-13559 SF#:00002812
Fixed an issue with the Pass Through Authentication Plugin where if a DN map was not used, the controls from the native bind operation were included in the pass through authentication request. Issue:DS-13644 SF#:2847
Updated the create-systemd-script tool by adding resource limits for available open file descriptors (NOFILE), and shared memory reservations (MEMLOCK). The generated script lists the recommended file descriptors limit and the resource limit setting for enabling large page support. The settings in the create-systemd-script output supersedes prior documentation for setting the number of open file descriptors on non-systemd systems. Issue:DS-13678
Updated the ldif-diff tool to ensure that change records for delete operations will be ordered to ensure that a delete for a parent entry will never come before the deletes for its children. Issue:DS-13748
Added a new Commonly-Used Passwords instance of the dictionary password validator that uses a dictionary file with 10,000 of the most common user passwords as determined by analysis of data from a number of security breaches. Because these passwords are so popular among end users, they are also very commonly guessed by attackers trying to compromise end user accounts.
The Commonly-Used Passwords validator is defined in the out-of-the-box configuration, but is only invoked by the Secure Password Policy by default. Issue:DS-10775
Updated the initial output of export-ldif to report that it is calculating a disk-ordered cursor rather than "Exported 0 entries." Issue:DS-13771
Updated the server to allow an initial heap size over 128 GB. Due to limitations of older JVMs, this was previously capped at 128 GB, even when the maximum heap size was larger. Issue:DS-13554
Enhanced the server's support for storing and interacting with JSON objects.
It is now possible to configure indexes for specified fields inside JSON objects to accelerate JSON object filter extensible match search operations. Indexes can be used for fields with boolean, integer, null, and string values and JSON object filters of type equals, equalsAny, greaterThan, lessThan, and substring, as well as AND filters that contain at least one indexed component and OR filters that contain only indexed components. Note that greaterThan and lessThan filters that target string values can only be indexed if they use case-insensitive matching.
It is now possible to indicate that the values of specified fields (ideally fields with a relatively small set of distinct values) should be tokenized when they are stored in the database. Tokenized values can be stored more efficiently, and consume less space in memory and on disk.
It is now possible to define a number of constraints for the fields that may be included in JSON objects stored in values of a specified attribute type. Constraints that may be imposed on a JSON field include: - Require values of the field to have a specified data type. - Indicate whether the field is required or optional. - Indicate whether the field is permitted to have multiple values in an array. If a field is permitted to have array values, then it is also possible to place restrictions on the number of elements that may be present in the array. - Indicate whether the field is permitted to have a value that is the null primitive as an alternative to values of the indicated data type. - Restrict values of string fields to a predefined set of allowed values, to values matching a given regular expression, or to values of a specified length. - Restrict values of numeric fields with upper and lower bounds. Issues:DS-12139,DS-12917,DS-13476,DS-13538
Added support for a new "Haystack" password validator based on the concept of password haystacks as described at https://www.grc.com/haystack.htm. It estimates the strength of a password using a combination of its length and the types of characters that it contains (e.g., a longer password containing only lowercase letters may be stronger than a shorter password containing a mix of uppercase and lowercase letters, numbers, and symbols).
The Haystack password validator is defined in the out-of-the-box configuration but is only enabled by default in the secure password policy. Issue:DS-12106
Added support for a "name with entryUUID" request control. If this control is included in an add request, the entry will be added with a distinguished name whose RDN contains only the entryUUID attribute. This offers a number of potential benefits:
Updated the server to better utilize worker threads and reduce the potential for a work queue backlog when processing multiple concurrent long-running operations. Issue:DS-13783
Fixed an issue involving transactions sent through a Proxy Server with Entry Balancing configured. If the transaction contained requests that targeted entries that were not in the global index, then duplicate requests were included in the resulting Multi-Update operation forwarded to the Data Store. Issue:DS-13820 SF#:2851
Updated interactive dsconfig to include an option to toggle between sorting similar properties together or sorting them alphabetically. Issue:DS-1706
Added an Identify References virtual attribute provider. Virtual attributes of this type will have values that are the DNs of entries that contain a specified attribute with a value that matches the DN of the entry containing the virtual attribute. For example, this could be used to create a virtual directReports attribute whose values are the DNs of the entries that list the target user as their manager. Issue:DS-13727
Fixed a conflict between the Changelog Password Encryption plugin and the replication historical ds-sync-hist attribute that would result in a "historical information for this attribute seems to be corrupt" error message in the logs. Issue:DS-13484
The collect-support-data tool now has the option to collect logging information within a specified time range via the '--timeRange' argument. Issue:DS-1261
Updated the server to use the latest 6.4.9 release of Berkeley DB Java Edition. Issue:DS-13856
Improved the server's support for selecting TLS cipher suites. When the server is configured to use a specific set of cipher suites, it will now always validate that all of the configured suites are supported by the JVM. When the server is not configured to use a specific set of cipher suites, it will now customize the set of default suites to prioritize those using strong cryptography (especially those that offer forward secrecy), and exclude suites with known weaknesses. Issues:DS-12681,DS-13475
Updated the alert handler configuration to indicate whether the alert handler should be invoked asynchronously in a background thread rather than by the thread that generated the alert. For alerts generated during the course of processing an operation, invoking potentially time-consuming alert handlers in a background thread can avoid adversely impacting the response time for that operation while still ensuring that administrators are made aware of the issue that arose. Issue:DS-12833
Updated the server to provide support for SMTP connection pooling. When sending an email message, the server will attempt to reuse an existing SMTP connection rather than establishing a new connection for each message. Issue:DS-12833
Deprecated the invalid-attribute-syntax-behavior global configuration property in favor of a new permit-syntax-violations-for-attribute global configuration property. The new option makes it possible to allow malformed values for an explicitly-specified set of attribute types, whereas the former option could only be used to enable or disable syntax enforcement for all attribute types.
When migrating from a directory service that did not properly enforce attribute syntax compliance, it is strongly recommended that the data be cleaned to correct any malformed values that it may contain. However, in cases where that may not be immediately feasible, it is strongly recommended that syntax validation be relaxed only for attribute types that are known to have problems so that it will still be performed for other attribute types to prevent inadvertently introducing additional malformed values.
In the event that an LDIF file contains malformed values, the import-ldif tool will now provide a list of the attribute types with attribute syntax violations and the number of malformed values identified for each attribute type. As before, the specific violations can be identified by instructing the import-ldif tool to generate a rejects file, which will include a comment with each rejected entry to describe the reason the entry was rejected.
In addition, the server will now always perform syntax validation for the aci attribute type, regardless of the values of the invalid-attribute-syntax-behavior and permit-syntax-violations-for-attribute properties. This will provide additional assurance that malformed access control instructions cannot be introduced into the server during LDIF import processing. The server will still discover and validate all ACIs on startup, and will still place itself in lockdown mode on finding a malformed ACI rather than attempting to run with an incomplete access control configuration. Issues:DS-11823,DS-13535,DS-13894
Updated the account status notification handler configuration to indicate whether the handler should be invoked asynchronously in a background thread rather than by the thread that triggered the notification. For account status notifications generated during the course of processing an operation, invoking notification handlers in a background thread can avoid adversely impacting the response time for that operation. Issue:DS-12833
Fixed a problem that could cause the server to incorrectly handle the require-change-by-time property in the password policy configuration. Issue:DS-13140
A new index is now considered trusted if the server can determine that the associated attribute type (or JSON field for a JSON index) is not used in the data already contained in the target backend. If an index is automatically trusted, it is not necessary to use the rebuild-index tool to initialize that index. Issue:DS-12178
Fixed an issue with large password history duration values that may have prevented some passwords in the history from being considered a match when a new password with the same value was added. Issue:DS-13899 SF#:2813
Updated the server to use the latest 6.4.12 release of the Berkeley DB Java Edition. This version addresses a possible data corruption bug in versions 6.3.0 to 6.4.11. Issue:DS-14014
Fixed an issue where dynamic group membership searches lead to resource and memory leaks. Issue:DS-13983 SF#:00002944
Fixed an issue where password history values could be duplicated in replicated environments. Issue:DS-14036
Fixed an issue where replication would stall while performing searches on LDAP referrals. Issue:DS-14099 SF#:00002985
Fixed issues pertaining to search references. One caused replication to stall, and the other caused multiple copies of the same reference to be returned in a single search. Issue:DS-14116 SF#:2985
Added the ability to protect Velocity templates using the basic authentication scheme. Issue:DS-14074
Updated the server's password policy support to make a few account usability enhancements:
Fixed a couple of corner cases in which the server could treat smart referrals improperly. This includes search operations based above smart referrals contained in entries whose DNs contain escaped commas, as well as some search and compare operations based at least one level below a smart referral. Issue:DS-14133
Fix an issue in the SCIM interface where an attribute required by the SCIM schema could be deleted by a PATCH operation. Issue:DS-14060
Fixed a log publisher defect that would result in an unreadable file when both compression and signing were enabled at the same time. Issue:DS-13552
Updated the LDAP connection handler to enable the use of multiple threads for accepting connections and preparing them for use. This improves concurrency for deployments in which the process of accepting a new connection may take some time to complete, possibly because of expensive DNS lookups or invoking time-consuming post-connect plugins). Issue:DS-12627
Updated the server to generate an administrative alert if it detects that a database environment was not closed cleanly and may require a time-consuming recovery process. Issue:DS-13794
Updated the email OTP delivery mechanism to allow retrieving email addresses from fields contained inside JSON objects, optionally using a JSON object filter to select which of several addresses should be used (e.g., only attempt to use verified email addresses). Similar changes have been made to the Twilio OTP delivery mechanism for obtaining phone numbers for SMS messages. Issue:DS-14259
The ldifsearch command now supports the option "---isCompressed" for LDIF files that have been compressed with gzip. Issue:DS-14140
Added properties to the task backend for limiting the number of log messages retained in task entries, in order to limit the size of the in-memory representation of those entries. All log messages generated by a task will still be recorded in the server error log, even if they are not all retained in the corresponding entry in the task backend. Issue:DS-11067 SF#:2282
Updated the server to reject search requests that attempt to make use of an invalid JSON object filter. The server would previously return a success result with no matching entries. Issue:DS-12933
Fixed a race condition that could arise from simultaneous attempts to add entries with an attribute value that would cause an exploded index key to exceed its index entry limit. Issue:DS-14311
Updated the server to discourage conflicts between indexes and virtual attributes. A search that targets an indexed attribute will only identify entries with real values as potential matches, and may omit entries that match the filter if they match because of a virtually-generated value. Issue:DS-13862
Added password storage schemes that leverage the Bcrypt and scrypt key derivation functions. These storage schemes require the free and open source Bouncy Castle library, which is not included with the server. This library must be obtained from https://bouncycastle.org/ and placed in the server lib directory before these storage schemes can be used. Issues:DS-14398,DS-14399
Fixed an issue with the collect-support-data tool when using the --pid argument. Only one jstack was being collected, instead of using the amount specified by the --maxJstacks argument. Issue:DS-14349
Updated the report generated by import-ldif to include database cache requirements for each possible cache-mode per backend database (e.g., attribute index). This aids tuning environments that cannot be fully cached. Issue:DS-12312
These issues were resolved with version 5.1.5.2 of the Directory Server:
Fixed an issue where replication would stall while performing searches on LDAP referrals. Issue:DS-14099 SF#:00002985
Fixed issues pertaining to search references. One caused replication to stall, and the other caused multiple copies of the same reference to be returned in a single search. Issue:DS-14116 SF#:2985
Added the ability to protect Velocity templates using the basic authentication scheme. Issue:DS-14074
Fixed a couple of corner cases in which the server could treat smart referrals improperly. This includes search operations based above smart referrals contained in entries whose DNs contain escaped commas, as well as some search and compare operations based at least one level below a smart referral. Issue:DS-14133
These issues were resolved with version 5.1.5.1 of the Directory Server:
Fixed a conflict between the Changelog Password Encryption plugin and the replication historical ds-sync-hist attribute that would result in a "historical information for this attribute seems to be corrupt" error message in the logs. Issue:DS-13484
Fixed an issue with large password history duration values that may have prevented some passwords in the history from being considered a match when a new password with the same value was added. Issue:DS-13899 SF#:2813
Updated the server to use the latest 6.3.10 release of the Berkeley DB Java Edition. This version addresses a possible data corruption bug in versions 6.3.0 to 6.3.9. Issue:DS-14015
Fixed an issue where dynamic group membership searches lead to resource and memory leaks. Issue:DS-13983 SF#:00002944
Fixed an issue where password history values could be duplicated in replicated environments. Issue:DS-14036
These features were added for version 5.1.5.0 of the Directory Server:
Data within the backend database is now stored more compactly both on disk and in memory. The exact benefits depend on the data set and indexing, but improvements of 20-40% should be expected in the size on disk, the memory needed to fully cache the database, the time to preload the database at start up, the size and duration of backups, and the time required to remotely initialize a replica. Upgrades of existing environments require an export and reimport of the data to take advantage of these improvements.
These were known issues at the time of the release of version 5.1.5.0 of the Directory Server:
These issues were resolved with version 5.1.5.0 of the Directory Server:
Improved the server shutdown time in situations when there is a database cleaner backlog. This also ensures a faster start up time since database recovery isn't needed. Issue:DS-13207
Updated the local DB backend to always try to keep exploded indexes in the database cache, and to always load exploded indexes into the cache on startup if database preloading is enabled, even if the database containing non-exploded index data for the associated index is configured with a lesser cache mode or preload configuration. Because reading from exploded indexes requires much more database interaction than non-exploded indexes, this can dramatically improve the performance of exploded index accesses for deployments in which it is not possible to fully cache all data in the backend. Issue:DS-13182
Updated the server to use the latest 6.3.9 release of the Berkeley DB Java Edition. Issue:DS-13426
Fixed an edge case problem in which a password change could result in the previous password not being included in the password history. Issue:DS-13481 SF#:2813
Updated the installer to increase the maximum suggested JVM size on Linux systems with at least 48 GB of RAM. Issue:DS-12982
Fixed an issue that could cause the server to overlook attribute options in an indexed search filter. Issue:DS-13559 SF#:00002812
Fixed an issue with the Pass Through Authentication Plugin where if a DN map was not used, the controls from the native bind operation were included in the pass through authentication request. Issue:DS-13644 SF#:2847
Added a gauge to monitor the number of available file descriptors. This Available File Descriptors gauge can detect if a server if running out of file descriptors and degrade the server appropriately. Issue:DS-12727
Updated the initial output of export-ldif to report that it is calculating a disk-ordered cursor rather than "Exported 0 entries." Issue:DS-13771
Updated the server to allow an initial heap size over 128 GB. Due to limitations of older JVMs, this was previously capped at 128 GB, even when the maximum heap size was larger. Issue:DS-13554
Fixed an issue involving transactions sent through a Proxy Server with Entry Balancing configured. If the transaction contained requests that targeted entries that were not in the global index, then duplicate requests were included in the resulting Multi-Update operation forwarded to the Data Store. Issue:DS-13820 SF#:2851
Important upgrade considerations for version 5.1.0.0 of the Directory Server:
The summarize-config tool is deprecated, and will be removed in future versions of the product. Use the config-diff tool with the "sourceBaseline" argument to list a summary of changes to the local server configuration.
These features were added for version 5.1.0.0 of the Directory Server:
Password Validators now have added properties for user-friendly descriptions and errors, which can be used by client applications to improve user interfaces.
The self-service password reset function that uses a one-time password (OTP) is now more streamlined. An OTP token can be sent to an end user through email or SMS, and used for authentication when setting a new password.
Added initial support for a JSON object attribute syntax, which can be used for attribute types whose values are JSON objects. Indexing options are currently limited. Please see the full release note below for DS-12138.
These were known issues at the time of the release of version 5.1.0.0 of the Directory Server:
These issues were resolved with version 5.1.0.0 of the Directory Server:
The setup tool has been updated to use HTTPS for initial configuration. Unsecure HTTP can be enabled post-setup, or by using non-interactive setup. Issue:DS-12182
Addressed cases where some messages may be suppressed in logs and alerts. Issue:DS-12287
Updated the server to automatically monitor and report the length of time each operation spends waiting in the work queue before a worker thread can begin to process it. Issue:DS-12218
Updated the local DB backend so that changes to the db-checkpointer-wakeup-interval property no longer require a restart to take effect, and to expose new monitor attributes with useful information about the processing performed by the database cleaner. Issue:DS-12263
Added a configuration option to enable a wait period before removing a 'server unavailable' alert after a garbage collection task is performed. This allows sub-systems like replication to restart before the server becomes available again. For the Periodic GC Plugin, this option is 'delay-post-gc.' For a Forced GC Task entry, the attribute is named 'ds-task-delay-post-gc.' Both options take a value in milliseconds, and have a default value equivalent to 20 seconds. Issue:DS-12318
Updated the Configuration API output where properties and their values are listed to include those that are undefined. Issue:DS-12123
Changed the default password policy behavior to prevent users from changing their passwords to their current password value. This logic will apply regardless of password history settings. Issue:DS-12313 SF#:2546
Added the 'listKeysExceedingIndexEntryLimit' argument to the verify-index tool, which enables listing the keys for indexes that have exceeded their index entry limits. Issue:DS-3186
Updated UnboundID work queue processing to log expensive work queue operations and diagnostic thread stack traces when a queue backlog alarm is raised. Issue:DS-12319
Added support for running on Oracle Java 8 and OpenJDK 8 platforms. Issue:DS-12483
Fixed an issue that generated the following error message, but did not impact the current operation: "An unexpected error occurred while notifying a change notification listener of a modify operation: RuntimeException: The specified condition must be true. The error occurred at com.unboundid.directory.server.types.AuthenticationInfo.replaceUserEntries." Issue:DS-12443
Fixed an issue where configuring numeric IPv4 address filtering by connection criteria in a log publisher performed unnecessary reverse hostname lookups. Issue:DS-12610 SF#:00002632
Added features to allow clients to better determine the set of requirements that the server will impose for user passwords. The get password quality requirements extended operation can be used to retrieve information about the requirements before an attempted password change. Those requirements can be conveyed to the end user, and can potentially be used to enable some types of client-side validation to identify problems with a password before it is sent to the server. The password validation details request control can be included in an add request, a modify request, or a password modify extended request to identify which specific validation requirements may not have been met by the password provided in the request.
Password validators can be configured with user-friendly messages that better describe the constraints that the validator will impose for passwords, and that the validator should return if a proposed password does not satisfy those constraints. The server will generate these messages if they are not provided in the configuration. Issues:DS-12107,DS-12137
Added the ability to reset user passwords with a single-use, time-limited token that is delivered to the end user through some out-of-band mechanism like SMS or email. After determining the identity of the user for whom the password reset token should be generated, an application can use the new "deliver password reset token" extended operation to cause the server to create and deliver the token to the user. This token can then be provided to the "password modify" extended operation in lieu of the user's current password in order to allow that user to select a new password. Password reset tokens can optionally permit users to reset their passwords even if their account is not usable (for example, because their account is locked or their password is expired). Issue:DS-8739
Updated the notification destination cn=monitor entry (objectclass of ds-notification-destination-monitor-entry) to include an attribute, ds-notification-age-of-next-pending-change-seconds, which tracks how out-of-date the destination is in seconds. Values are only maintained on the master server for that domain (ds-notification-master=true). A value of 0 on the master server for that domain indicates that the destination is up-to-date. This attribute can be used in a gauge to generate alarms if a destination gets too far behind. Issue:DS-12618 SF#:2597
Added logging of all HTTP requests disallowed due to CORS. This should make it easier to debug HTTP 403/Forbidden errors. Issue:DS-12496
Critical: The server can now detect an "out of file handles" situation on the operating system, and shut down to prevent running in an unreliable state. Issue:DS-12579 SF#:2655
Update the Detailed HTTP Operation Log Publisher to log the correct return code (404 NOT FOUND) when a request is not handled by defined endpoints. Issue:DS-12576
The Configuration API has been updated to support filtering, sorting, and paging for object list operations. See the Administration guide for usage. Issue:DS-12245
Added support for a JSON object attribute syntax, which can be used for attribute types whose values are JSON objects. The syntax requires that each value of this type is a valid JSON object. Two matching rules have also been added for use in conjunction with the JSON object syntax: jsonObjectExactMatch and jsonObjectFilterExtensibleMatch.
The jsonObjectExactMatch equality matching rule is used in evaluating equality filters in search operations, as well as for matching performed against JSON object attributes for add, compare, and modify operations. It determines whether two values are logically-equivalent JSON objects. The field names used in both objects must match exactly (although fields may appear in different orders). The values of each field must have the same data types. String values will be compared in a case-insensitive manner. The order of elements in arrays will be considered significant.
The jsonObjectFilterExtensibleMatch matching rule can perform more powerful matching against JSON objects. The assertion values for these extensible matching filters should be JSON objects that express the constraints for the matching. These JSON object filters are described in detail in the Javadoc documentation (available in the Commercial Edition of the UnboundID LDAP SDK for Java) for the com.unboundid.ldap.sdk.unboundidds.json.JSONObjectFilter class and its subclasses. Although the LDAP SDK can facilitate searches with this matching rule, these searches can be issued through any LDAP client API that supports extensible matching.
Indexing is supported only for the jsonObjectExactMatch matching rule. If possible, non-baseObject searches that use the jsonObjectFilterExtensibleMatch matching rule should be wrapped in an LDAP AND filter that also contains one or more indexed components so that the search can be processed more efficiently. Issue:DS-12138
Fixed an issue where changes to SMTP External Server configurations did not take effect until after a server restart. Issue:DS-12285
Added support for three new extended operations for interacting with single-use tokens:
- The "get supported OTP delivery mechanisms" operation provides information about which one-time password delivery mechanisms are configured in the server, and which of those are available for a specified user.
- The "deliver single-use token" operation can generate a token value and provide it to a specified user through an out-of-band communication mechanism like email, SMS, or voice call.
- The "consume single-use token" operation indicates that the user has received a single-use token from the "deliver single-use token" operation, and to consume that token so that it cannot be reused. Issues:DS-12594,DS-12596
Fixed an issue where the Data Store parsed the last login time value using the wrong time zone. The incorrect time affected password policy decisions and was delivered in the response to a password policy state extended request. Issue:DS-12943
Updated the server to avoid the use of the server-side sort and virtual list view request controls in search requests that span multiple subtree views or multiple entry-balanced backend sets. If the server cannot honor a non-critical server-side sort or virtual list view control, then it will process the search operation as if the control had not been included in the request. If the server cannot honor a critical server-side sort or virtual list view control, then it will return an error result to the client. Issues:DS-12560,DS-12561
Fixed a rare condition that might cause the logger rotation and retention thread to exit under heavy file system load or a network file system outage. Issue:DS-12880
MakeLDIF templates now have the ability to escape special characters curly braces, angle brackets, and square brackets using a backslash. See config/MakeLDIF/examples-of-all-tags.template for further examples. Issue:DS-12798
Improved server locking used by dsconfig in offline batch mode, so that the server lock is held for the entire batch duration, instead of for each invocation. Also, reduced the probability of contention for file locks used by server tools to determine the server status. Issue:DS-12969 SF#:2717
Added the ability to configure the Globally-Unique Attribute and Unique Attribute plugins with a filter to limit attribute uniqueness checking to a subset of matching entries. Issue:DS-9842
Fixed the Local DB Backend configuration help text for deadlock-retry-limit, which incorrectly stated that a value of zero would result in unlimited retry attempts. That value actually results in no retry attempts. Issue:DS-12909
JDBC external servers now give precedence to settings in the jdbc-driver-url property, over other dsconfig JDBC Managed Object settings for host-name, port, and database-name. The jdbc-driver-url property setting can be used instead of the other JDBC Managed Object settings. Issue:DS-12700
Reduced the memory overhead of debug logging in high throughput environments by sharing logging buffers across multiple threads. Issue:DS-10010
Fixed an issue in the Server SDK where the ServerContext sendAlert method incorrectly generated a Java RuntimeException when attempting to send a third-party extension alert. Issue:DS-12995
These issues were resolved with version 5.0.1.0 of the Directory Server:
The setup tool has been updated to use HTTPS when configuring the HTTP Connection Handler(s). Unsecure HTTP can be enabled post-setup, or by using non-interactive setup. Issue:DS-12182
Addressed cases where some messages may be suppressed in logs and alerts. Issue:DS-12287
Updated the server to automatically monitor and report the length of time each operation spends waiting in the work queue before a worker thread can begin to process it. Issue:DS-12218

For a Forced GC Task entry, the attribute is named 'ds-task-delay-post-gc.' Both options take a value in milliseconds, and have a default value equivalent to 20 seconds. Issue:DS-12318
Updated the Configuration API output where properties and their values are listed to include those that are undefined. Issue:DS-12123
Changed the default password policy behavior to prevent users from changing their passwords to their current password value. This logic will apply regardless of password history settings. Issue:DS-12313 SF#:2546
Added the 'listKeysExceedingIndexEntryLimit' argument to the verify-index tool, which enables listing the keys for indexes that have exceeded their index entry limits. Issue:DS-3186
Updated UnboundID work queue processing to log expensive work queue operations and diagnostic thread stack traces when a queue backlog alarm is raised. Issue:DS-12319
Fixed an issue that generated the following error message, but did not impact the current operation: "An unexpected error occurred while notifying a change notification listener of a modify operation: RuntimeException: The specified condition must be true. The error occurred at com.unboundid.directory.server.types.AuthenticationInfo.replaceUserEntries." Issue:DS-12443

The server can now detect an "out of file handles" situation on the operating system, and shut down to prevent running in an unreliable state. Issue:DS-12579 SF#:2655
These features were added for version 5.0.0.0 of the Directory Server:
Java 7 is now required when setting up a new server or upgrading an existing server.
Added support for extensible match filters that can make assertions about the number of values that a specified attribute has in an entry. For example, the extensible match filter "(cn:valueCountEquals:=1)" will match an entry only if that entry has exactly one value for the cn attribute. The following special matching rules have been added to help provide this capability:
- valueCountEquals - valueCountDoesNotEqual - valueCountGreaterThan - valueCountGreaterThanOrEqualTo - valueCountLessThan - valueCountLessThanOrEqualTo
Updated the LDAP changelog to support selecting which entries should be included in or excluded from the changelog. Entries can be selected based on the location of the target entry in the DIT, and/or based on whether the changelog entry matches a given filter.
A new ds-changelog-target-attribute attribute has also been added to changelog entries to indicate which attributes were involved in the change. This may be used to select changelog entries for inclusion or exclusion based on changes to specific attributes.
Enabled support for the SSLv2Hello TLS protocol by default in JVMs that support it. This does not enable support for the insecure SSLv2 protocol, but it can improve compatibility with clients running older versions of Java that may start TLS negotiation with an SSLv2 client hello packet before negotiating to a higher version of the TLS protocol. Support for SSLv2Hello in the initial phase of negotiation does not in any way compromise the strength of the integrity and/or confidentiality protection that is ultimately negotiated between the client and the server.
Added a Monitor History plugin that periodically records cn=monitor to timestamped files to aid in isolating intermittent problems. By default, it logs the full cn=monitor branch every five minutes to compressed files within logs/monitor-history/. Files are deleted automatically, but a sparse set of older files are kept to provide historical perspective on server performance. The collect-support-data tool has also been updated to collect a few of these files to aid in root cause analysis.
Updated the server to use the latest 6.2.31 release of the Berkeley DB Java Edition.
The default SCIM base context path changed from / to /scim. Any clients using the previous base context path will no longer be able to access SCIM services until they are updated. The following dsconfig command may be used to revert to the previous base context path after update:
dsconfig set-http-servlet-extension-prop --extension-name SCIM --set base-context-path:/
Introduced the Configuration HTTP Servlet Extension, which can be used for querying and updating the configuration over a REST API. This feature is currently experimental and is subject to change in the future. Your feedback is welcome.
Improved the diagnostic information the server can provide at startup for any components that take a substantial amount of time to initialize. The server will also generate an alert notification if any component attempts to perform an unindexed internal search operation, in order to warn about potential misconfiguration.
Added a global configuration setting called database-on-virtualized-or-network-storage. This boolean setting must be set to true when database files will be stored on network filesystems. It should be set to false if the database is on a local disk since it incurs a performance penalty.
These were known issues at the time of the release of version 5.0.0.0 of the Directory Server:
These issues were resolved with version 5.0.0.0 of the Directory Server:
Fixed the gauge configuration manager to only re-initialize the gauge that was changed, and not any of the other gauges that did not change. Issue:DS-11472
Fixed the alarm manager to generate alarm-cleared alerts when internal alarms are cleared and the alarm manager's generated-alert-types property has the "alarm" value. Issue:DS-11541 SF#:2421
Updated the javadoc for the Example Overload Handler plugin to include the argument "invoke-for-internal-operations" with a value of "false" during the plugin creation. Previously, the plugin, when enabled, would drop internal queries to the monitor backend initiated by the gauge state provider.
Fixed an issue in the Example Overload Handler plugin's applyConfiguration method, where when any changes were made to the plugin's configuration itself (such as adding a new pre-parse type), it would drop requests because we were doing an LDAP search for the gauge argument in the config backend over a client connection, instead of using an internal connection.
Fixed an issue where when the Example Overload Handler plugin was disabled and then re-enabled, an IllegalStateException occurred because the monitor provider that publishes drop stats was previously registered. Issue:DS-11565 SF#:00002421
Fixed the alarm manager to not include the details of the old alarm, (the alarm being cleared), in the "alarm-cleared" alert message. Issue:DS-11546
Updated gauge alert details to include the last threshold value that was crossed. Issue:DS-11396
Fixed the dsconfig tool to suppress all stray output when run in batch mode with the --quiet option. Issue:DS-10460
Fixed a rare issue in backend database entry encoding where the server alerted on an "unexpected exception" when encoding large entries with an unusually large number of ds-sync-hist values. The error was reported in the alert message as being a NegativeArraySizeException thrown from the EntryEncoder class. Issue:DS-11625
Fixed an issue in which tools such as dsconfig, status, and dsreplication could not connect to the server over SSL or StartTLS. This occurred when a certificate was accepted with the 'Manually validate' option, while using the interactive LDAP connection menu. Issue:DS-11688
Critical: Added a fail safe to the pending changes queue for the Changelog Backend that can detect and ignore recovered changes that do not need to be committed in order to prevent holding up other changes in the queue. Issue:DS-11720 SF#:2453
Updated the alarm manager to not generate "alarm-normal" alert when a gauge's condition abates Issue:DS-11637
Reduced the severity of the "unrecognized alert type" message in the error log from SEVERE_WARNING to NOTICE. The message now states that this is expected if the server is reverted to a version prior to the implementation of these alert types. Issue:DS-11453
Removed the "alarm-normal" alert. Issue:DS-11730
Updated the server so that alarm-cleared, alarm-warning, alarm-minor, alarm-major, and alarm-critical alerts are not subject to duplicate alert suppression. Separate alert notifications of these types may represent distinct conditions and resources that should not be suppressed. Issue:DS-11738
Updated the set subtree accessibility extended operation handler to support atomically altering the accessibility of multiple subtrees in a single request. Issue:DS-11483
Updated the alarm manager to not persist normal alarms. Issue:DS-11719
Updated the ExampleOverloadHandlerPlugin to monitor the alarm backend for delete actions, so that it can react appropriately to abating gauge conditions. Issue:DS-11719
Critical: Disabled support for SSLv3 by default in the LDAP, HTTP, and JMX connection handlers, and for replication communication. The recently-discovered POODLE vulnerability could potentially allow a network attacker to determine the plaintext behind an SSLv3-encrypted session, which would effectively negate the primary benefit of the encryption.
SSLv3 was initially defined in 1996, but was supplanted by the release of the TLSv1 definition in 1999 (and subsequently by TLSv1.1 in 2006 and TLSv1.2 in 2008). These newer TLS protocols are not susceptible to the POODLE vulnerability, and the server has supported them (and preferred them over SSLv3) for many years. The act of disabling SSLv3 by default should not have any adverse effect on clients that support any of the newer TLS protocols. However, if there are any legacy client applications that attempt to communicate securely but do not support the newer TLS protocols, they should be updated to support the newer protocols. In the event that there are known clients that do not support any security protocol newer than SSLv3 and that cannot be immediately updated to support a newer protocol, SSLv3 support can be re-enabled using the newly-introduced allowed-insecure-tls-protocol global configuration property. However, since communication using SSLv3 can no longer be considered secure, it is strongly recommended that every effort be made to update all known clients still using SSLv3.
It is possible to use the server access log to identify LDAP clients that use SSLv3 to communicate with the server. Whenever an LDAP client establishes a secure connection to the server, or whenever a client uses the StartTLS extended operation to secure an existing plaintext connection, the server will generate a SECURITY-NEGOTIATION access log message. The "protocol" element of a SECURITY-NEGOTIATION access log message specifies the name of the security protocol that has been negotiated between the client and the server, and any SECURITY-NEGOTIATION messages with a protocol of "SSLv3" suggest that the associated client is vulnerable to the POODLE attack. In addition, if any connections are terminated for attempting to use the disallowed SSLv3 protocol, the access log message for that disconnect should include a message stating the reason for the termination. Issue:DS-11782
Updated the Web Console so that upon login, the user's old session is always invalidated. Issue:DS-11624
Updated the Web Console to suppress LDAP responses in user messages, such as when the server is unavailable or for authentication failures. Also added a context parameter to exclude stack traces and detailed error messages from appearing in the application's internal error page. Issues:DS-11629,DS-11645
Updated numeric gauges so that their severity changes when the current gauge value equals the threshold's exit value. Previously the value had to be strictly less than the exit value for the severity to change. Issue:DS-11837
Updated the HTTP Detailed Access logger to use timestamps with millisecond precision. Issue:DS-11755
Updated the access logger to include usedPrivileges and/or missingPrivileges fields in result log messages for operations in which the requester used one or more privileges, or in cases where the requested operation required one or more privileges that the requester did not have. Issue:DS-11805
Fixed incorrect property references for trustStorePassword and keyStorePasswordFile in tools.properties that corresponded to the wrong argument names. Issue:DS-11751
Fixed an issue where the server would hang during startup due to a previous unexpected service outage resulting in an empty tasks.ldif file. Issue:DS-11868
Computed minimums, averages, maximums in statistics loggers previously processed infinite or out-of-range numbers leading to unprintable character output in comma-separated value (CSV) files. Computed minimums, averages, maximums in statistics loggers now exclude infinite and out-of-range values. Issue:DS-11913
Fixed a replication issue where the changelogDb path on the destination server was incorrect when the following conditions were met: the source and destination shared the same installation path, the source server used a symlink for changelogDb to an external path, the destination server did not have the external path. Issue:DS-11892 SF#:2486
Added additional debug information for constraint violations that can happen during replication enable. Issue:DS-11839 SF#:2482
Fixed an issue where deleting values of a multi-valued attribute using SCIM PATCH could silently fail. Modifications in SCIM PATCH are now mapped directly to LDAP modifications to take advantage of the matching rules configured in the Identity Data Store, when matching deleted values. Since the SCIM PATCH is now applied by the Data Store, the Permissive Modify Request Control (1.2.840.113556.1.4.1413) is now required by the SCIM component. This will ensure that adding an existing value or deleting a non-existent value in the PATCH request will not result in an error.
To continue using SCIM component after an upgrade of the Identity Data Store or Identity Proxy, access controls and configuration may need to be updated to allow access to the Permissive Modify Request Control.
Identity Data Store:
dsconfig set-access-control-handler-prop --remove 'global-aci:(targetcontrol="1.3.6.1.1.13.2 || 1.2.840.113556.1.4.473 || 1.2.840.113556.1.4.319 || 2.16.840.1.113730.3.4.9 || 1.3.6.1.1.12")(version 3.0;acl "Authenticated access to controls used by the SCIM servlet extension"; allow (all) userdn="ldap:///all";)'

dsconfig set-request-processor-prop --processor-name dc_example_dc_com-req-processor --add supported-control-oid:1.2.840.113556.1.4.1413
Note that "dc_example_dc_com-req-processor" is the default processor name and it may be different depending on your configuration.
Identity Broker: For each Identity Data Store used as an user store, the following configuration changes are required:
dsconfig set-access-control-handler-prop --remove 'global-aci:(targetcontrol="1.3.6.1.1.13.2||1.3.6.1.4.1.30221.2.5.3||1.3.6.1.4.1.30221.2.5.25||1.2.840.113556.1.4.1413||1.3.6.1.4.1.30221.2.5.5||2.16.840.1.113730.3.4.9||1.2.840.113556.1.4.473||1.2.840.113556.1.4.319")(version 3.0; acl "Broker User access to selected controls"; allow (read) userdn="ldap:///cn=Broker User,cn=Root DNs,cn=config";)'
dsconfig set-access-control-handler-prop --add 'global-aci:(targetcontrol="1.3.6.1.1.13.2||1.3.6.1.4.1.30221.2.5.3||1.3.6.1.4.1.30221.2.5.25||1.2.840.113556.1.4.1413||1.3.6.1.4.1.30221.2.5.5||2.16.840.1.113730.3.4.9||1.2.840.113556.1.4.473||1.2.840.113556.1.4.319||1.2.840.113556.1.4.1413”)(version 3.0; acl "Broker User access to selected controls"; allow (read) userdn="ldap:///cn=Broker User,cn=Root DNs,cn=config";)'
Note that the user DN "cn=Broker User,cn=Root DNs,cn=config" is default user name created when the external store is prepared. It may be different depending on your configuration. Issue:DS-11138
Fixed a bug that resulted in an error message related to performing a modify DN operation against a currently authenticated user entry. Issue:DS-11728
When using SCIM, the method in which the username in HTTP Basic authentication are mapped to a user is now configurable using Identity Mappers. Once the username is mapped to a user, a simple BIND request will be used to verify the password. Issue:DS-11908
Added change type indexes to the LDAP changelog to improve the efficiency of get changelog batch operations that target records with only a subset of change types. Issue:DS-11933
Added the ability for a Server SDK extension, such as a Plugin, to register for notifications when an operation completes using the OperationContext#registerOperationCompletedListener() method. Issue:DS-11406
Fixed an issue where a password policy was configured to record the last login time and last login IP address, but those attributes were not being updated when a bind went through the pass-through authentication plugin to a remote server. Issue:DS-11996 SF#:2526
Fixed an issue where a password policy was adding login failures when a bind went through the pass-through authentication plugin, and failed locally, but subsequently succeeded against an external server. Issue:DS-12010 SF#:2526
Added a new schema file that contains previously undefined server attributes. The addition of these attributes helps resolve conflicts with user-defined schema. Issue:DS-3629
Fixed a rare condition where parent DNs stored in compact form for evaluation of group membership could consume a large amount of memory. Issue:DS-12005 SF#:00002531
Updated the configuration properties of the Local DB Backend to indicate which settings require a component (or server) restart to take effect. Issue:DS-12032
Fulfilled an enhancement request to allow access to the additional information properties in alert notifications. Issue:DS-12040 SF#:00002528
Added a workaround for a bug in some versions of Java that could interfere with the ability to restore an encrypted backup. Issue:DS-11902
Fixed an issue where attempting to cancel many outstanding proxy operations could make the proxy server unresponsive. Issue:DS-12000 SF#:00002535
Fixed a problem with startup dependencies not being properly honored for Server SDK plugins. Issue:DS-12066
Fixed the index rebuild job so that it does not generate redundant "index-degraded" alerts when an index is being rebuilt. Issue:DS-11879
Fixed an issue that caused replication to disconnect for up to fifteen minutes when sending on half open connections, typically due an unforeseen network issue. Issue:DS-12027 SF#:2534
Fixed an issue where replication would not be established for a new replica when it was initialized by importing an LDIF file exported from an existing replica. The issue occurred whether the import was performed before or after enabling replication. Issues:DS-11774,DS-9877
Fixed an issue where the server could hit an unexpected exception when a new attribute index was added while the server was under heavy load. Issue:DS-12064
Fixed an issue that could interfere with rebuilding an attribute index with one or more exploded index keys. Issue:DS-11919
Disabled log rotation during startup to prevent potential problems with rotation dependencies on server components that have not yet been initialized. Issue:DS-10441
Added a configuration option that can be used to indicate that an attribute index should maintain a matching entry count for keys that exceed the index entry limit. While maintaining a count for these index keys will not improve the efficiency of applicable searches, the count can be used to improve the result the server is able to return for these searches when used in conjunction with the matching entry count request control. Issue:DS-12109
Added a gauge to the server to track JVM memory usage and alert if the amount of free memory gets low enough that it could impact server performance. Issue:DS-11993
Updated the server to make it easier to control the order of values in the ssl-protocol and ssl-cipher-suite properties in the LDAP connection handler and crypto manager configuration objects. Issue:DS-12147
The dsreplication remove-defunct-server subcommand no longer allows the removal of a running server from the replication topology. Issue:DS-12124
Updated the character set password validator to allow for adding optional character sets that require zero or more matches. Issue:DS-12162
Updated the server's support for filtered indexes so that they can be used for a broader set of search filters. Issue:DS-12170
Simplified the various cache-mode properties within the Local DB Backend configuration. Current values for these properties are "cache-keys-and-values" (formerly "default"), "cache-keys-only" (formerly "evict-leaf-immediately"), and "no-caching" (formerly "evict-bin-immediately"). The old values will continue to work. If the update tool is used to upgrade to this release, the existing values within the configuration will be updated to use the new values. Issue:DS-11297
Fixed an issue where registering a server extension would cause a null-pointer exception at startup preventing the server from starting. Issue:DS-12174
Updated the HTTP Connection Handler to return a 404 Not Found response to requests for endpoints not handled by any servlet or web application extensions. Previously the hander would return a 200 OK with no response body. Issues:DS-12120,DS-8368
Updated the rebuild-index tool to add offline support for approximate indexes. Issue:DS-12197
Fixed an issue with the verify-index tool that could arise when examining approximate indexes with one or more keys exceeding the index entry limit. Issue:DS-12197
Fixed an issue where updating a component in the web console could generate a missing enabled property error. Issue:DS-12201
Fix an issue where a VLV request specifying a large afterCount value would result in an OutOfMemoryError and cause the Data Store to shut down. Issue:DS-12215
Updated the HTTP/HTTPS connection handler to Jetty 8.1.16.v20140903. Issue:DS-11959
These features were added for version 4.7.0.0 of the Directory Server:
Updated the server to support Alarms. An alarm represents a stateful condition of the server that might indicate a problem, such as low disk space or external server unavailability. The status command line utility and the monitoring page of the web console have been updated to expose the active alarms. Many existing alert types have been updated to be treated as alarms. When the condition associated with an alarm abates, the alarm is cleared.
Added support for Gauges. A gauge examines specific server monitoring data, and raises an alarm when a configured threshold is crossed. The server has out-of-the-box gauges such as CPU Usage and Disk Busy, and new ones can be added through the Gauge Data Source and Gauge configuration object types.
The end-to-end replication latency is continuously calculated and exposed through the replica's monitor entry. The Replication Latency gauge can be configured to raise an alarm if the measured latency exceeds a specified threshold.
Added support for a matching entry count request control that uses server index data to quickly determine the number of entries that match the associated search request. The matching entry count response control will indicate whether the value is an exact count or an upper bound, and may contain additional debug messages describing the use of indexes to derive that count. This functionality is exposed on the ldapsearch command line tool with the --countEntries option.
Exposed more fine-grained control of transaction locking and retry. Added local DB backend configuration properties that can be used to specify default transaction settings that will be used for external transactions (LDAP transactions or atomic multi-update operations) that do not include a transaction settings request control. Added support for a transaction settings request control that can be used to customize the behavior of the server when processing a batched transaction or an atomic multi-update operation. Customizable settings include the commit durability, the number of retry attempts, the conditions under which to acquire an exclusive lock in the target backend while the commit is in progress, and upper and lower bounds for transaction lock timeouts.
Enhanced Replication Health Monitoring and Alarms.
OpenJDK 7 is now supported on Linux.
These were known issues at the time of the release of version 4.7.0.0 of the Directory Server:
JDK 6 is currently deprecated and will not be supported in the next major release.
UnboundID products are not supported on JDK 8.
The following attributes are not defined in the Unbound ID Data Store schema, but are being used by the product. Please do not use the following: baseDN, certificate, hostname, id, instancePath, jmxEnabled, jmxport, jmxsEnabled, jmxsport, ldapEnabled, ldapport, ldapsEnabled, ldapsport, location, memberofgroups, os, preferredSecurity, replicationPort, startTLSEnabled, type.
These issues were resolved with version 4.7.0.0 of the Directory Server:
Task-based invocations of the restore tool now require that the "backupDirectory" parameter have an absolute path. Issue:DS-9110
Fixed the web console so that attempts to reconnect (after the console is restarted) succeed. Issue:DS-11043
Added additional processing to the Unique Attribute Plugin that eliminates a race condition where concurrent operations were previously allowed to create entries with the same unique value. Issue:DS-11086 SF#:2307
Updated the processing time histogram to use a more sensible format for aggregate percent values. The LDAP SDK monitor parsing support for this monitor entry has also been updated to accommodate either format. Issue:DS-11146
Added support for a new hex string attribute syntax, which is intended to store values comprised of zero or more hexadecimal digits. Hex string values may be compacted, so that the representation stored in the database uses less memory and disk space than the string representation that will be used when clients interact with the data. Issue:DS-10813
Added support for compacting the values of attributes configured to use an integer or bit string syntax. Compacted values can require less space to store in the database and less memory to hold in the cache, particularly for values with larger non-compacted representations.
Compaction for integer and bit string values is not enabled by default because certain values that violate the constraints of the syntax could be incorrectly interpreted as if they had been compacted. If the server has ever been configured to permit attribute values that violate syntax constraints, it is recommended that the data be exported to LDIF before enabling compaction and imported from LDIF after compaction has been enabled. Issue:DS-10783
Added local DB backend configuration properties that can be used to specify default transaction settings that will be used for external transactions (LDAP transactions or atomic multi-update operations) that do not include a transaction settings request control. Issue:DS-10555
Added a result code tracker that maintains a monitor entry with counts and response times of results. Each result is categorized by operation type, post-response result code, and whether it is a failure or non-failure. Issue:DS-3270
Exposed LDAP extended operation throughput and response time data in the Periodic Stats Logger and the Metrics Engine to expand upon the set of tracked operation types. Issue:DS-10369
Exposed local & non-local external server health check states in the Proxy load balancer monitor entry. Issue:DS-10552
Fixed an issue with HTTP Connection Handlers that allowed them to be configured with ports that were already in use. Now the server will not start if an HTTP Connection Handler is configured to use a port that is in use. Issue:DS-11202
Changed automatic tuning for db-num-cleaner-threads in the JE Backend to set a maximum of two cleaner threads. Previously, automatic tuning set a maximum of 16 threads depending on the number of available CPUs, and unneeded cleaner threads decreased performance. If a greater number of cleaner threads is needed to keep up with server load, the server will generate an alert with suggested configuration changes. Issue:DS-2356
Fixed a bug where in a rare case the server may take 10 minutes to start due to waiting on non-existent replication backlog. The server will now will start without delay if there no backlog to process or report the on the progress of the backlog count every 30 seconds until the start up backlog threshold is met. Issues:DS-11182,DS-11195 SF#:2332
The default value for the Global Configuration property startup-min-replication-backlog-count has been changed from unlimited to 5000 to avoid starting connection handlers before the server has a chance to catch up on replicated updates. A server that has been offline for an extended period if time will take longer to start up, but once it is started, it will expose up-to-date data. Issue:DS-11285
Updated the mirror and isMemberOf virtual attribute providers to take advantage of the matching entry count functionality when determining whether a given search operation may be processed efficiently with the virtual attribute provider. Previously, these virtual attribute providers may have incorrectly concluded that a search could be processed efficiently when the criteria would not have been indexed as expected (e.g., because one or more index keys needed to perform the search had exceeded the index entry limit), resulting in a search that took longer to process than if the virtual attribute provider had not been used. Issue:DS-11108 SF#:00002323
Fixed a problem in which the server could encounter an internal error when processing a substring search for an attribute type that does not have a substring matching rule, but for which an equality index is defined. The server will now return an inappropriate matching result for attempts to evaluate a search filter in which a necessary matching rule is not available. Issue:DS-11345
To ensure consistent response times, the server actively alerts when its threads are paused for more than a few seconds due to environmental issues. Causes may include running within a virtualized environment, disk swapping, and garbage collection. With this change, the server uses information provided by the JVM about recent garbage collection pauses to either rule out garbage collection as the source of the detected pause, or to provide details about the type of garbage collection that could have caused the pause. Issue:DS-10930
Enhance the changelog backend to work with LDAP clients sensitive to the distinction between moddn and modrdn values in the changetype attribute. Issue:DS-11394 SF#:2392
Added tracking of extended operations by type to the LDAP Result Code Tracker to increase the granularity of reported data. Issue:DS-11011
Updated the attribute constraint validation check for 'X-MIN-INT-VALUE' to allow negative integer values to be specified. Issue:DS-11441 SF#:00002401
Fixed a problem that prevented the server from starting if a TLS-enabled connection handler was configured with a certificate nickname that referenced a non-RSA certificate. Issue:DS-10949
Fixed an internal server error resulting from a multi-update request containing only password modify extended requests with target identities not prefixed with "dn:". Issue:DS-11449
These issues were resolved with version 4.6.0.0 of the Directory Server:
Upgrade to Berkeley DB Java Edition version 5.0.103.
Updated the local DB backend to improve support for exploded indexes:
- Fixed a bug that could cause the server to improperly count the number of entries matching an exploded index key, which could interfere with the correct enforcement of the index entry limit for exploded index keys.
- Updated the server so that if an exploded index key has exceeded the index entry limit, the data associated with that index key will be deleted in the background so that the result to the client will not be delayed.
The server has also been updated to improve the diagnostic information that will be made available in the event of a database deadlock, lock timeout, or transaction timeout. Issues:DS-10277,DS-10278,DS-10279 SF#:00002147
Updated the validate-file-signature tool to ensure that it will always display a final summary message to indicate whether any warnings or errors were encountered during processing. Issue:DS-10333
Updated the signed logging implementation to better handle any problems that may arise during cryptographic processing. If any such problem is encountered, the server will now include a message with information about the error in the signature block rather than suspending the logger with an exception recorded in the server.out log file. Issue:DS-10310
The replication conflict resolution policy has been changed for attributes defined in the schema as single-value. The new policy for these attributes is that the last write always takes effect in the event of a conflict. Previously, in cases where two different values were added on different servers very close to the same time, the intended policy was to have the first value take effect across all the replicas. However, this former policy could result in replica divergence in the presence of three or more replicas. Issues:DS-10063,DS-9855
Fixed an issue in the Periodic Stats Logger, where no logging would occur when suppress-if-idle=true was configured, even when the server was not idle. Issue:DS-10387 SF#:2170
Fixed the artifacts associated with the first bind failure that crosses the lockout failure count set in the Password Policy. Previously, the Password Policy Response control would not accurately reflect that the account was locked, and the account locked time was not being updated. Issues:DS-10398,DS-10399 SF#:2148
Added a new sanitize-log tool that can be used to remove sensitive information from server log files, including the file-based access log, the operation timing access log, the file-based error log, the file-based sync log, the file-based resync log, and the detailed HTTP operation log.
The sanitization process operates on fields that consist of name-value pairs. The field name and equal sign will always be retained, but in cases where the value may contain sensitive data, that value may either be replaced with the string "---REDACTED---", or it may be tokenized. If the tokenized value is a DN or filter, then attribute names in that DN or filter will be preserved while the values will be replaced with a string consisting of a number inside curly braces. If the tokenized value is not a DN or filter, then the entire value will be replaced with a number inside curly braces. If a string to be tokenized appears multiple times in the log, the same replacement token will be used for each occurrence of that string to make it possible to correlate occurrences of that string without revealing the actual content.
The sanitize-log tool has a default configuration that should be sufficient for many environments, allowing it to tokenize or redact sensitive information while preserving non-sensitive content for use in diagnosing problems or understanding usage patterns. However, this behavior can be customized using command-line arguments by indicating whether to preserve, tokenize, or redact a given log field. Issue:DS-10472
Fixed issues with the JDBC Access Logger that were related to Oracle Thin Client, where column values were "null" and disabling the logger resulted in losing a connection to the server when using the dsconfig command. Issue:DS-10485
Critical: Fixed a problem that could interfere with access to an exploded attribute index after performing an online index rebuild for that attribute. Issue:DS-10470
Updated the Server SDK to add the ability to generate administrative alert notifications that cause the server to report itself as degraded or unavailable. Issue:DS-10499
Improved performance for ACI calculations involving complex search filters by trying to reduce the number of redundant access calculations when multiple filter components refer to the same attribute type. Issue:DS-10528 SF#:2212
Updated the server and replication infrastructure so that tasks for initializing one or more servers over the network can be canceled with the manage-tasks tool. When an initialization task is initiated by dsreplication, instructions to cancel the task are printed to the console. When an initialization task is canceled, the target backend is left empty and disabled, and must be re-enabled before another initialization can be attempted. Issue:DS-9999
Fixed an issue with the Password Modify Extended Request used with the Password Policy Control, where the "Password in History" error type was not being set properly. Also, in the case of "Insufficient Password Quality," a diagnostic message is provided in the extended result. Issue:DS-10592 SF#:2220
Fixed an issue so that collect-support-data now generates filename entries correctly. Previously, the tool would hang if the archiving of files following a symbolic link required generating a non-duplicating filename entry. Issue:DS-10582
Fixed Time Rotation Policies could be triggered twice in succession if a backwards time system clock adjustment is made during log rotation. This condition may be triggered by network time protocol updates or virtualization host-to-guest time synchronization. The fix was to record the time of file comparison and not allow the last rotation time to be set to a time earlier than the time of comparison. Issue:DS-10591 SF#:2205
Enabled the Host System Monitor Provider by default so that system CPU and memory utilization will be reported automatically through the server's monitoring framework. Disk and network monitoring can be enabled by configuring values for the disk-devices and network-devices configuration properties. Issue:DS-10562
The default timeout period for smtp-timeout was changed from none to two minutes to prevent non-responsive mail servers from disrupting administrative functions. Issue:DS-10230
Introduced a limit to the number of changes a replica is allowed to hold that are pending communication to the replication server. Issue:DS-10605 SF#:2218
Fixed an issue with dsreplication status where the tool would fail to parse an IPv6 server address when using the displayServerTable option. Issue:DS-10668 SF#:2223
The dsreplication detach command was deprecated in a previous release and has now been removed. To remove or isolate a server from the replication topology, use dsreplication disable. This command will remove the server from a replication topology for a given base DN. Issues:DS-10146,DS-9913
With the implementation of Java 7, the log-file-permissions setting now provides more granular permissions for users and groups. Issue:DS-6241
Fixed an issue in which subtree delete operations that were part of an LDAP transaction were not replicated properly and could interfere with the replication of new changes. Issue:DS-10871 SF#:2257
The setup command no longer saves user-provided key store and trust store passwords in PIN files. Passwords provided during setup are encrypted with the configuration data. If the administrator chooses to use PIN files to supply the passwords, the files are referenced in the server configuration by the key manager and trust manager. Issue:DS-10787
Updated the access control handler configuration to make it easier to specify which controls clients are allowed to include in bind requests. Issue:DS-10725
Updated the access logger so that result messages include user-friendly names for result codes in addition to their numeric values. Issue:DS-9946
Updated the Periodic Stats Logger to include an empty value in the output rather than "infinity" in certain circumstances. This avoids problems plotting the output in a spreadsheet. Issue:DS-8842
Fixed the exchange of symmetric keys used when importing or restoring encrypted data. The exchange was not working when the servers defined in admin data were configured to use secure authentication. This would result in error message "CryptoManager failed to import the symmetric key" during a restart of the server. Issue:DS-10896 SF#:2253
Fixed an issue where ldap-diff would stop working when it encountered an invalid DN from one of the servers. The command now finishes processing, but ignores invalid entries. Issue:DS-10650
Updated dsconfig to treat tabs as whitespace in batch files. Issue:DS-10549
Added Metrics Collection Size Limit Retention Policy to the metrics backend to allow up to 2 GB of metric data to be buffered locally, which allows the Metrics Engine to be offline for a longer time without missing collected data. Issue:DS-10156
Removed deprecated "lshal" command from Linux-specific processes performed by the collect-support-data tool and added similar command, "udevadm info --export-db" Issue:DS-10713
Delete requests going through an entry balancing request processor no longer require the requester to have permission to use the pre-read request control (1.3.6.1.1.13.1) on the backend servers. The pre-read request can be used to keep the global index up to date for deleted entries, but it requires explicitly adding permission for this control on the backend servers. This functionality can be enabled by setting the advanced "global-index-update-method-for-deletes" configuration option for entry balancing request processors to "pre-read-request-control." Issue:DS-10961 SF#:2260
Fixed a problem that could cause a VLV index to be improperly maintained in cases in which a large number of entries had the same values for all of the attributes defined in the sort order. Issue:DS-10971 SF#:00002278
Updated the Replication Servers table produced by the dsreplication tool to omit unnecessary "Security" column. Issue:DS-10442
Clients with the 'privilege-change' privilege are now able to add entries with ds-privilege-name values through the proxy server. Issue:DS-10935
Corrected an issue where virtual attribute processing for base entry searches by privileged users caused virtual and operational attributes to be returned when defining a search entry plugin. Issue:DS-10992 SF#:2283
These features were added for version 4.5.1.0 of the Directory Server:
Password rotation is now supported. The Identity Data Store now has the ability to associate multiple passwords and expiration dates with a single account. This enables new client credentials to be rolled out over time instead of all at once.
The import-ldif command now reports on-disk and in-RAM database sizes for planning and estimating. The tool also makes configuration recommendations based on results.
SCIM Resource Versioning (ETag) is now supported. This enables clients to detect overlapping updates for the Identity Data Store and Identity Proxy SCIM interfaces.
The dsreplication tool now reports the number of entries in conflict, to facilitate monitoring of replication issues.
Attributes that are stored only on disk ("un-cached attributes") are now compressed automatically to reduce storage requirements
The collect-support-data tool now refers to tools.properties for default command-line options.
The collect-support-data tool now supports an option to encrypt the data archive, to ensure protection of customer data while in transit, and an option to reduce the amount of potentially sensitive data that is collected.
Cross-origin Resource sharing (CORS) support is now included for HTTP Servlet Extensions, including the SCIM RESTful APIs.
Add support for SCIM resource versioning.
These were known issues at the time of the release of version 4.5.1.0 of the Directory Server:
Disable support for interactive transactions by default. The use of interactive transactions in some cases is prone to creating database deadlocks which may result in one or more operations being delayed and/or aborted, and in most cases, the use of standard LDAP transactions, the LDAP assertions control, the LDAP read entry controls, and/or the increment modify extension provide a sufficient level of atomicity for operations. Issue:DS-9954
The dsreplication initialize and initialize-all subcommands are not supported if run from a server that is a version prior to 4.5.0.0. When executed in a replicated environment containing old and new server versions, dsreplication can take several minutes to report the unsupported use-case when using initialize-all. Issue:DS-9904
The SCIM REST client, included with the SCIM SDK, may hang while waiting for responses from the UnboundID SCIM implementation when using Java 6. This is due to a JDK issue, which was fixed in Java 7. If this condition is encountered, the latest version of Java 7 can be used with the client application to work around the issue. Issue:DS-10104
A SCIM request from a client application cannot contain null JSON elements in request bodies to represent attributes that have no values. Instead, the request should not include the attributes. Issue:DS-10105
If an application that was used in a consent operation is deleted, the Identity Broker's /privacy/v1/histories/{ownerCompositeKey}/accessHistory resource will show that application as null in its responses. This causes the following error with the Privacy Preferences application when requesting access history:
An error occurred: "Unexpected AJAX error message format." Issue:DS-10203
When the Velocity servlet receives CORS-enabled requests and has a cross-origin policy in effect, it will return multiple Access-Control-* headers with duplicate values. This will cause cross-origin requests issued by web browsers to fail. Issue:DS-10205
These issues were resolved with version 4.5.1.0 of the Directory Server:
Update the make-ldif tool to no longer assign the objectClass value of extensibleObject to branch entries. If needed, "objectClass: extensibleObject" can be added explicitly to the branch definition. Issue:DS-8530
The output of 'dsreplication status' now includes a separate column for the number of replication conflict entries, rather than including these entries in the entry count. The number of regular entries shown should now be the same across all servers (except for prior version servers) in a system where replication conflicts have been resolved. Issue:DS-7306
Fix a bug where authentication with SCIM would fail because the password provided contains a colon character. Note: HTTP Basic Authentication does not allow for usernames to contain a colon character, but LDAP DNs can, so avoid using DNs with a colon when authenticating with SCIM. Issue:DS-10045 SF#:2112
Provide an advanced configuration property db-file-cache-size for the JE database file handle cache size. Increase the default size from 100 to 1000 for better performance with large databases. Issue:DS-9540
The setup tool's --aggressiveJVMTuning and --verboseGC command-line options have been deprecated. Instead, use --jvmTuningParameter AGGRESSIVE and --jvmTuningParameter VERBOSE_GC respectively. Issue:DS-9079
Add support for a password retirement feature. If enabled, whenever a user's password is changed, the server will retire the user's former password in a way that allows it to continue to be used for a configurable length of time. This makes it possible to have a grace period when changing a password so that applications which have been configured with the previous password will still be able to authenticate with that password until they can be updated with the new password.
This capability is disabled by default but can be enabled to automatically retire user passwords on self changes and/or administrative resets. It is also possible to allow passwords to be retired via the use of a control included in a modify request or a password modify extended request. Issue:DS-9848 SF#:00002075
Update the server configuration to use a new default limit for duplicate alert suppression. The previous default imposed a maximum of 100 alerts of the same type per hour. The new default imposes a maximum of 10 alerts of the same type every ten minutes. This is more likely to suppress bursts in which the same alert is repeatedly generated over a short time without interfering with multiple occurrences of alerts of the same type over a longer period of time. Issue:DS-9259
Add an example usage for the rebuild-index tool that demonstrates the arguments needed to run the tool as a task. Issue:DS-8922
Fix a bug in which the implementation for third-party result criteria created via the Server SDK did not provide access to additional details about a search operation, including the number of entries and/or references returned, and whether the search was indexed. Issue:DS-10057
Update the backup compatibility mechanism to warn on an attempt to restore a backup from a server that contained one or more encryption settings definitions into a server that does not have all of those definitions. Any entries encrypted with the settings contained in one of those definitions will be inaccessible to a server that does not contain those definitions. Issue:DS-9918
Update the import-ldif tool to report a detailed breakdown of the database cache requirements of the imported data set. This includes targeted warnings if the current server configuration is not optimized for the imported data set as well as recommendations for the largest data sets that are cacheable both for the current server configuration and for the machine with the most aggressive memory tuning options. A few summary tables are included in the output that is reported by the tool. Additional details, including the memory requirements for each index, are included in the logs/tools directory in both .txt and .csv formats. Issues:DS-6977,DS-8835
Fix a bug that could cause multiple persistent search notifications for operations associated with an interactive transaction or an atomic multi-update operation. Issue:DS-7433
Update the server so that uncached data is automatically compressed. Issue:DS-9539
For a number of LDAP-enabled tools that support including arbitrary controls in requests, the tool supports the use of a user-friendly name instead of the OID for certain controls. This was not previously documented, but the tool usage for the "--control" argument now provides those user-friendly names so they are easier to use. Issue:DS-8685
Fix the dsreplication disable subcommand to allow disabling servers that missed replication updates. Issue:DS-7244
Disable support for interactive transactions by default. The use of interactive transactions in some cases is prone to creating database deadlocks which may result in one or more operations being delayed and/or aborted, and in most cases, the use of standard LDAP transactions, the LDAP assertions control, the LDAP read entry controls, and/or the increment modify extension provide a sufficient level of atomicity for operations. Interactive transaction support can be enabled if this capability is still required.
Note that for environments which use the large attribute feature (which has been deprecated in favor of uncached attributes), interactive transactions are still required, and an attempt to start a server with a large attribute backend but without support for interactive transactions will cause the server to enter lockdown mode. Any customers using large attributes that wish to update to the latest version of the server should first contact support to determine the best way to perform the update. Issue:DS-9954
Update the server to improve the caching behavior for PIN files as used by key and trust manager providers. In the case that the keystore or truststore file has been updated to require a new PIN and the existing PIN file is updated without a configuration change to the associated key or trust manager provider, the server would previously keep trying to use the old PIN. It will now look for and use an updated PIN if a failure is encountered while using the old PIN. Issue:DS-10113 SF#:2123
Update the collect-support-data tool so that it can encrypt the data that is captured to protect it from unauthorized third parties. The encryption key is generated from a passphrase which may be read from a file, interactively provided by the user, or dynamically generated by the tool. This passphrase must be provided to support personnel (ideally over a different communication channel than the encrypted support data archive itself) for them to be able to access the information it contains.
There is also a new option to decrypt an encrypted collect-support-data archive when provided with the encryption passphrase. Issue:DS-10129
Update the collect-support-data tool so that it is possible to configure default values for most arguments in the tools.properties file. Issue:DS-10178
Update the collect-support-data tool to further reduce the possibility of gathering sensitive information. Potentially sensitive data will be replaced with ---REDACTED--- in the output. A new "--securityLevel maximum" option can also be specified that redacts DNs and search filters, which might include personally identifiable information. Issue:DS-10115
These features were added for version 4.5.0.0 of the Directory Server:
The Replication Initialization process has been enhanced to use binary transfers, removing the need to perform binary copy of large databases.
Tampering detection is now available for audit files.
Combined search operations that process using indexes with those that process by virtual attribute providers, and operations that target multiple virtual attributes are supported.
The dsreplication command now supports SASL binding, which enables Kerberos authentication without the use of passwords.
A new config-diff command line utility can compare two server configurations and produce the difference as a dsconfig batch file. The file can then be used to bring the source configuration in line with the target. Comparisons can be done between live servers or configuration files, and between current or legacy configurations. Run 'config-diff --help' to get more information including example use cases.
These were known issues at the time of the release of version 4.5.0.0 of the Directory Server:
The dsreplication detach command is deprecated. This command can be run, but will generate warnings if used either interactively or non-interactively. To remove or isolate a server from the replication topology, use dsreplication disable. This command will remove the server from a replication topology for a given base DN. Issue:DS-9919
When executed in a replicated environment containing old and new server versions, dsreplication can take several minutes to report the unsupported use-case when using initialize-all. Issue:DS-9904
Java 1.7 has a synchronization bottleneck in HashMap that severely impacts performance. Use update 1.7u40, if possible, to avoid this issue. Issue:DS-9477
It is no longer possible to customize the format in which last access time values are written. Now values are written in the generalized time syntax. A new max-update-frequency property can be used to limit how often an entry's access time is updated. If an entry does not have a last access time, the modifyTimestamp can be used to reduce the rate of access time updates when the feature is initially enabled. Issue:DS-8360
These issues were resolved with version 4.5.0.0 of the Directory Server:
Update the Identity Access API to automatically map LDAP attributes using the Generalized Time attribute syntax to the SCIM DateTime data type. Issue:DS-9758
Update SCIM and the Identity Access API to return a 400 status code when the id attribute is included in a PATCH request, as the id attribute is read-only. Issue:DS-9195
Fix a bug in the JDBC Access Logger that could cause incompatibility with some database versions and display a "Cannot commit when autoCommit is enabled" error message. Issue:DS-8750
Fix a bug when shutting down replication nodes, that could result in multiple shutdown attempts for the same node. Issue:DS-8790 SF#:1906
Update the Server SDK to provide a new EnhancedPasswordStorageScheme API that both simplifies the API needed to create custom password policies and makes it possible for the password storage scheme to have access to the full user entry so that it is possible to use information from that entry in the process of generating or verifying encoded passwords. Issue:DS-8429
Update the out-of-the-box configuration to add a sensitive attribute definition for the TOTP shared secret. This definition will not be enforced by default, but it can be easily enabled by referencing it from the global configuration or the desired set of client connection policies. Issue:DS-8769
Update the global ACIs so that the retain identity request control will be allowed by default. Issue:DS-8710
If the server is configured with one or more global sensitive attribute definitions, internal operations may be subject to restrictions imposed by some sensitive attributes. This is often the correct behavior, but there are some cases in which sensitive attribute restrictions may interfere with correct processing (e.g., if a sensitive attribute is also configured as a unique attribute, then the unique attribute plugin may have previously been blocked from performing the necessary search to determine whether there are any conflicting values). To address this problem, the server has been updated so that some internal operations are allowed to be exempted from sensitive attribute restrictions to ensure that they are able to behave correctly. Issue:DS-7849
Update the server startup process so that if no messages have been logged for at least five minutes, the server will generate and log a message about the current phase of startup processing. This can help reassure administrators that the server is still starting and provide information about what phase of startup may be taking so long. Issue:DS-7450
Update the TOTP SASL mechanism handler to provide an option that will prevent TOTP passwords from being used multiple times, even in the same time interval. Issue:DS-8738
Enable the validate TOTP password extended operation handler in the out-of-the-box configuration. Issue:DS-8756
Update the server to allow the start administrative session extended request on an unauthenticated connection even if the reject-unauthenticated-requests global configuration property is set to true, and on an insecure connection even if the reject-insecure-requests property is set to true. The server would previously reject the attempt to create an administrative session under these circumstances, which could interfere with the ability to bind or use StartTLS in cases where all normal worker threads are tied up and unable to process new requests in a timely manner. Issue:DS-8717
Update the file-based cipher stream provider so that it only needs access to the PIN file when the server is started (or when invoking a command-line tool that needs to open the encryption settings database). This makes it possible to store the PIN file on removable media (e.g., a USB drive) that is only mounted as-needed to reduce the likelihood that someone with access to the system will be able to obtain the PIN needed to access the data encryption keys. Issue:DS-8736
Fix a potential deadlock when enabling replication in a large topology. Issue:DS-8790 SF#:1906
Add support for a new password storage scheme that uses the PBKDF2 algorithm (as described in the PKCS#5 specification contained in RFC 2898). This scheme uses multiple rounds of cryptographic processing to make brute force (and even dictionary) attacks much more expensive. The salt length, iteration count, and derived key length can be customized by the administrator if desired. Issue:DS-8680
Add a new wait for passphrase cipher stream provider that can be used to allow the passphrase for the encryption settings database to be provided interactively by an administrator without the need to have it stored anywhere on the server system. A new "supply-passphrase" subcommand has been added to the encryption-settings tool that can be used to provide this passphrase when it is needed during server startup or when this cipher stream provider is first put into service. Issue:DS-8737
Fix a bug that could result in a replica that resisted becoming a WAN gateway after disconnecting from catch-up mode. Issue:DS-8830 SF#:1910
Fix a memory leak that could affect long-lived connections that are used to process a large number of non-anonymous bind operations without using the retain identity control. Issue:DS-8833
Fix an issue where the setup process could produce a java error file due to a native memory allocation failure. Issue:DS-6412
Update java.properties generation so that comments related to alternative JVM tunings are no longer present in the file. In most cases, rather than updating java.properties by hand you should use the dsjavaproperties tool to generate JVM options. Issue:DS-8339
Add an allow-insecure-local-jmx-access option to the global config that will expose JMX data via insecure local JVM connection Issue:DS-4300
Add support for a new multifactor authentication mechanism that uses one-time passwords that have been delivered to the end user through some out-of band mechanism. The authentication is performed in a two-step process:
- The client first sends a "deliver one-time password" extended request, which includes an authentication ID to identify the target user, the static password for that user, and an optional list of allowed delivery mechanisms. If successful, this extended request will cause a one-time password to be generated and made available to the user through some mechanism (the server comes with support for delivering one-time passwords through e-mail via SMTP, and through SMS using the Twilio web service, and it also includes Server SDK support for creating custom delivery mechanisms).
- Once the user has received the one-time password, they may use it to authenticate via the UNBOUNDID-DELIVERED-OTP SASL mechanism, which includes an authentication ID, an optional authorization ID, and the one-time password value that was provided to them.
A new deliver-one-time-password command-line tool has been provided to make it possible to test the extended request used to provide the one-time password to the user, and all command-line tools that support SASL authentication have been updated to make it possible to use the UNBOUNDID-DELIVERED-OTP SASL mechanism. Issue:DS-6969
Fix a bug where pwdChangedTime was not being updated when using the update-local-password option in the pass through authentication plugin. Issue:DS-8856 SF#:1932
Add a new alert handler that can use the Twilio service to deliver administrative alerts via SMS. Long alerts may be either truncated or split into multiple SMS messages. Issue:DS-5587
Update the configuration schema to make the ds-cfg-inherit-default-root-privileges attribute mandatory for object class ds-cfg-root-dn-user which is used to define Root User DNs. When this attribute is not present on Root DN User entries, the effect is for the root user to inherit default privileges. It has been made mandatory to make this behavior more explicit. During an update of the server, root DN user entries that do not explicitly declare a value for this attribute will be updated with a value of 'true'. Issue:DS-8450
Fix a bug in which setting the show-all-attributes property to true in the root DSE or schema backends could cause the associated operational attributes to behave incorrectly if they appeared in other entries in the server (e.g., if this setting was enabled for the root DSE, then it could cuase the subschemaSubentry operational attribute to behave as a user attribute in other entries as well). Issue:DS-8788
Improve performance when large static groups are retrieved over SCIM. The UnboundID Join Request Control is used to gather the attributes needed from each member entry and return them from the data store in a single operation. Issue:DS-7681
Add arguments to import-ldif to allow excluding operational and replication attributes from being imported. Issue:DS-5991
Add 'jmap -histo:live' to collectSupportData when --collectExpensiveData is set Issue:DS-8783
Ensure that the Pass-Through Authentication plugin updates the last login time and last login IP address when the update-local-password option is enabled. Issue:DS-8872
Fix a bug that prevented modify operations with sequential password modifications from completing as expected. Issue:DS-8880
Fix NullPointerException with missing arguments to dsreplication. Issue:DS-6738
Update the backup, restore, import-ldif, and export-ldif tools to provide support for data encryption and signing when they are running in a different JVM than the server. Previously, these functions were only available when the backup/restore/import/export processing was invoked as a task so that it would operate inside the running server. Issue:DS-166
Dramatically improve the performance of LDIF export when not running as a task (i.e., in a JVM that is outside the running server). Issue:DS-7340
Add the ability to use the simple paged results, server-side sort, and virtual list view request controls in conjunction with search operations that are processed using a virtual attribute provider. Issues:DS-6613,DS-6928
Fix a bug where ldapmodify would not accept multiple values for case sensitive attributes. Issue:DS-8911 SF#:1944
Add a WebLogic specific descriptor file for the web console to help with deployment compatibility. Issue:DS-8925 SF#:1915
Add help message for when user tries to rebuild-index while server is online. Issue:DS-1242
Add error messages for when incorrect arguments are supplied to dsconfig Issue:DS-7569
The trust store password options have been deprecated for most tools that do not require read-write access to a trust store. Issue:DS-8789
Add correct line number in error messages on make-ldif. Issue:DS-8018
Add correct ALU branding in create-sync-pipe-config. Issue:DS-8820
Update default sync pipe naming to be script friendly by replacing space characters with underscores. Issue:DS-3190
Make a number of criteria-related improvements:
- Add Server SDK support for creating custom connection, request, result, search entry, and search reference criteria implementations.
- Update the simple request criteria type to make it possible to consider the search scope in determining whether a search operation matches the criteria.
- Update the simple result criteria type to make it possible to consider the indexed/unindexed status in determining whether a search operation matches the criteria.
- Add a new type of request criteria that may be used to more easily identify operations that target the server root DSE.
- Add a new type of result criteria that may be used to classify operations based on replication assurance requirements and/or whether those requirements were satisfied.
- Add a new allowed-insecure-request-criteria global configuration property that may be used to identify requests that the server should allow even if they are received over an insecure connection and the server is configured to reject insecure requests.
- Add a new allowed-unauthenticated-request-criteria global configuration property that may be used to identify requests that the server should allow even if they are received over an unauthenticated connection and the server is configured to reject unauthenticated requests. Issues:DS-5079,DS-8168,DS-8770
Fix an issue in the Identity Data Store LDAP changelog which resulted in the Sync Server Notification Pipe missing changes under certain load patterns. Issue:DS-8901
Update the unique attribute plugin to make it possible to customize the behavior that the server should exhibit if the plugin is configured with multiple unique attributes. Uniqueness can be enforced independently for each attribute type, or as a set across all the configured attribute types (optionally permitting conflicts if they all appear in the same entry). Issue:DS-8209
Backup files and directories are no longer created with default world-readable permissions. The permissions to be used are instead configurable through the db-directory-permissions property for local DB backends and the changelog backend, and through the backup-file-permissions property for other types of backend. The default permissions provide no access to other users. Issue:DS-8749
Make two new tools available that can be used in conjunction with referential integrity and unique attribute processing:
Remove passwords when running collect-support-data Issue:DS-976
Update the server support for LDAP transactions (both standard LDAP transactions as described in RFC 5805, and the UnboundID-proprietary batched transactions implementation) to add support for proxied authorization by including a proxied authorization v1 or v2 control, or an intermediate client control with an alternate client identity, in the start transaction request. Issue:DS-8989
Add a new sign-log configuration property to file-based loggers that may be used to cause the server to digitally sign messages written by that logger. A new validate-file-signature tool may be used to verify signature information in signed log files, as well as LDIF files generated by signed LDIF exports. Issue:DS-8662
Fix a bug that prevented current and new passwords from being available to account status notification handlers for password changes and administrative resets made using the password modify extended operation. Issue:DS-9069
Fix a bug that treated passwords with curly braces as encoded with unknown password encoding scheme. The encoding check has been updated to verify that the password storage scheme referenced in a password string is valid and already registered with the server. Issue:DS-9093 SF#:1980
Update the local DB backend so that it will generate a warning when starting an LDIF export as a task. A task-based LDIF export may be unsafe because it cannot guarantee the kind of point-in-time snapshot of the data that an offline export provides, which means that the LDIF file resulting from a task-based export may reflect a portion of the changes processed while the export is in progress. The export-ldif tool usage has also been updated to provide the same warning. Issue:DS-7340
Update the Server SDK to make information about the target entry available in CompareResult, DeleteResult, ModifyResult, and ModifyDNResult classes, which makes it available for use by post-response and post-replication plugins. Issue:DS-9100 SF#:1951
Update the referential integrity plugin to prevent subtree delete operations when referential integrity is configured to operate in synchronous mode, which could result in database lock conflicts. Issue:DS-7940
Fix a bug that could prevent the server from properly maintaining ordering indexes for attributes with a generalized time syntax. Issue:DS-8952 SF#:1947
Update the last access time plugin (and the last access time uncached entry criteria, which depends on the last access time plugin) to change the way that last access time updates will be made.
It is no longer possible to customize the format in which last access time values are written. Rather, they will now always be written in the generalized time syntax, and a new max-update-frequency property may be used to limit how often an entry's access time may be updated. Further, if an entry does not have a last access time, then the modifyTimestamp may be used instead to help reduce the rate of access time updates when the feature is initially enabled.
When updating a deployment that uses the former last access time behavior, it is recommended that either all servers be updated in a short period of time or that the last access time plugin be temporarily disabled until all servers have been updated to a version that uses the newer approach. Otherwise, the rate of last access time updates may increase as long as the environment contains a mix of servers with older and newer versions. Issue:DS-8360
Fix a bug where group membership could incorrectly present a user as a member of a static group when that static group contained a dynamic group. Issue:DS-9159 SF#:1996
Add support for two new extended operations. A list configurations extended operation may be used to obtain information about the configurations that are available within to the server, including the currently-active configuration, the baseline configuration (i.e., the base configuration for an out-of-the-box installation of the current version), and all archived configurations that reflect configuration changes over time. A get configuration extended operation may be used to retrieve a specific configuration from the server. Issue:DS-9149
Update setup to fix a bug in which file path options specified as relative to the current directory may cause the server to be configured incorrectly or cause setup failure. Issue:DS-8389
Update the HTTP Connection handler to support configuration for tracking sessions either through HTTP cookies or by URL rewriting. Issues:DS-8639,DS-9128
Fix a bug where Changelog Password Encryption Plugin would throw an exception when processing a password change from an Active Directory Sync source. Issue:DS-9178 SF#:1954
Update the server's backup and restore capabilities so that backups will be stored with additional information about the state of the server and backend when the backup was taken so that potential compatibility problems may be identified when attempting to restore that backup. Issue:DS-8344
Update the server so that it will allow TLS renegotiation by default if it is running in a JVM that we can detect includes support for the extension described in RFC 5746. Older JVMs are vulnerable to a man-in-the-middle attack that could exploit a renegotiation flaw to inject arbitrary cleartext into a secure communication stream, and support for renegotiation was disabled by default to eliminate the possibility of such an attack against the server. However, modern JVMs have fixed the vulnerability and allowing TLS renegotiation in such systems can allow for better compatibility with clients that attempt to perform renegotiation. Issue:DS-6307 SF#:1972
Critical: Fix a bug in low level protocol buffer that could result in "uncaught exception" errors. Issue:DS-9268 SF#:2002
Address an issue in replication where the Identity Data Store may not shutdown in a timely fashion because monitor information requests are not handled efficiently Issue:DS-9232 SF#:2002
Update the server to provide a degree of sandboxing around Server SDK extensions so that an unexpected exception thrown by an extension will be caught and result in an administrative alert rather than being caught further up in the stack and potentially causing other problems. Issue:DS-9247
In the rare cases where it is necessary to forcefully terminate the JVM from within the server itself, ensure that any files marked for deletion when the JVM shuts down are manually deleted before the JVM is terminated. This can help avoid problems like server shutdown not being detected properly because the server PID file hasn't been removed. Issue:DS-9267
Provide improved schema validation to detect additional cases in which certain misspelled tokens in the definition for a schema token could be silently interpreted as an extra property for that schema element. The server will now log a warning message about these unexpected tokens so that administrators can either correct them or prefix them with "X-" to indicate that they are an extra property provided for informational purposes. Issue:DS-9236
Reduce the time it takes the server to shut down in certain situations. Background threads sometimes missed a signal to wake up and had to wait for their next polling interval to see that a shut down had been requested. Issue:DS-9334
Fix a defect where restricted domains were only being added to the configuration the first time replication was enabled. This would prevent you from being able to add new backends to the replication topology in an entry balanced environment where the baseDN of the new backend was inside the global domain baseDN.
If you are using an entry balanced environment and plan on adding new backends to your environment then you will need to upgrade to this release prior to adding these new backends. Issue:DS-9293
Fix a bug in the server that could cause a worker thread to become unable to send valid responses to operations if an unexpected exception was encountered while processing a search operation after that operation had already returned an odd number of entries. In such cases, subsequent operations processed by the worker thread could fail with a message like "The following constraint was violated. Entire search operation must be performed using the same thread from start to finish." Issue:DS-9086 SF#:00002024
Update the default behavior of all file-based loggers to have include-thread-id=true. This will include a compact thread ID in all log messages. This can make it easier to correlate log messages generated by the same thread within a single log file or across different types of log files. Issue:DS-9352
Remove -XX:+UseMembar from the default set of generated JVM properties except on early JVM versions where this setting was required to work around a threading bug in the JVM.
Update the server JVM arguments generated by setup and dsjavaproperties to explicitly define -XX:MaxNewSize and -XX:NewSize for JVM's 1GB in size and larger. Also, add a comment to the generated java.properties file directing the administrator to use dsjavaproperties for making memory-related changes to this file rather than editing it directly. Issue:DS-9227
Fix an issue where the server could return an invalid result code (-1) in a few exceptional cases. These cases have been updated to return the appropriate result code and a general check has been added to convert any future cases where this occurs into a generic but valid server error code. Issue:DS-9409
Update the server to emit a warning message when starting a backend that is configured with multiple base DNs. Although the server currently supports backends with multiple base DNs, this capability may be removed in a future release because some functionality (e.g., online replica initialization via binary copy) is not available for backends configured with multiple base DNs. Issue:DS-9146
Improve efficiency and reliability of shutdown process for replication database threads. Issue:DS-9400 SF#:2027
Fix a bug where modify operations that attempt a delete modification against an attribute that does not exist would not be preformed because the modification was incorrectly detected as a replication conflict and dropped in an attempt to resolve the conflict. Issue:DS-9431 SF#:2023
Add password file arguments to the scripts used to prepare external servers. Issue:DS-9406
The SCIM configuration for the Groups derived attribute now indicates whether to rely on the isMemberOf attribute or not. The default behavior is to rely on isMemberOf. This change eliminates unnecessary group membership searches in the case where an entry does not belong to any groups. Issue:DS-9051
Modify the way the server processes subtree delete operations so that they are no longer atomic, in order to avoid causing problems with potential database deadlocks or increased operation response times. In the event of a partial subtree delete, the server should generate an alert to notify administrators that a portion of the subtree still remains. Issues:DS-9020,DS-9174
Add a Log Publisher called "Debug ACI Logger" that can be enabled to help debug ACI issues. You can read more about debugging ACI related issues in the Admin Guide section "Troubleshooting ACI Evaluation". Issue:DS-8260
Update the make-ldif utility such that first and last names are now generated randomly instead of in sequential alphabetical order. The original ordered behavior can be enabled by using the --orderedNames option. Issue:DS-9504
Update the setup and dsjavaproperties tools to permit maximum heap size values for memory that is not currently available on the host, though the value must still be less than the total amount of memory present on the host. Issue:DS-9111
Fix an issue where the dsreplication adminPassword value provided in tools.properties was displayed in the clear on the command line. Issue:DS-9487
Fix a bug when using the force-change-on-reset option in the Password Policy for a replicated environment could result in the "pwdReset" flag being set on some replicas after a user resets their own password. Issue:DS-9547 SF#:2036
Update the setup and dsjavapropeties tools to permit JVM heap size values to be as large as the amount of memory present on the system would permit. Issue:DS-9494
Update the Server SDK to provide the ability to run command line utilities within the server process. A ToolExecutor can be retrieved from the ServerContext. Currently, only the config-diff command is supported, but additional commands might be supported in the future. Issue:DS-9537 SF#:00001858
Enhance dsconfig to write to the config audit log when in offline mode. Issue:DS-1495
Clean up a number of modify response messages for cases in which an invalid value was included in or targeted by the modify request. Formerly, some of these messages included attribute values, but this could result in very ugly output for tools and applications that displayed the message to the client in cases in which the value contained non-printable content. Issue:DS-8470
Change the replication status server table to display replica IDs instead of server IDs for each replica in a domain. Issue:DS-9206
Alter some potential error messages that could expose the server's key or trust store file path to the client if the server configuration for that key or trust store was not correct (e.g., if it was configured with an incorrect PIN). Issue:DS-8873
If an SSL certificate nickname is specified in the configuration of an LDAP connection handler (to indicate which certificate the server should present to clients), validate that the specified certificate is actually available via the configured key manager provider. Previously, it could be difficult to troubleshoot problems that may arise as the result of specifying the nickname for a nonexistent certificate. Issue:DS-8947
Fix a bug that could prevent persistent searches from receiving notification of changes processed as part of an external transaction. Issue:DS-8718
Fix a bug that could cause the update process to fail if the server to update was offline and the contents of the database directory had been removed. Issue:DS-9621
Add an option to collect replication state dump with collect support data. Issue:DS-9534
Upgrade to Berkeley DB Java Edition version 5.0.97. Issue:DS-9137
Fix a bug that could cause the server to incorrectly short-circuit the process of determining whether an entry had a specific attribute value if that entry contained both real and virtual values for the target attribute and the comparison took attribute options into consideration. Issue:DS-9631 SF#:00002047
Fix a bug that interfered with the ability to automatically re-encode passwords whenever a user attempted to authenticate with a password encoded with a deprecated storage scheme. Issue:DS-9767
On Linux, issue a warning on startup and after a JVM pause if the kernel setting vm.swappiness is not 0 as this can cause the server to become unresponsive for several seconds when memory is paged back from disk during a garbage collection. Issue:DS-9070
Display an error message rather than an exception stack trace when the encryption-settings tool is invoked without any arguments. Issue:DS-8892
Fix a bug in the index rebuild task in which, if the set of indexes to rebuild included one or more system indexes, the task would take the backend offline before rejecting the rebuild attempt and bringing the backend back online. The task will now reject the rebuild attempt without affecting the availability of the target backend. Issue:DS-8971
Fix a bug that prevented offline LDIF exports of the config backend. Issue:DS-9447
Automatically record server monitor data at shutdown, as it may be useful for debugging purposes in cases where a problem was experienced within the server that was resolved by a restart. Issue:DS-9777
Update the config definitions for the client connection policy and simple connection criteria objects to provide additional documentation about using connection criteria in conjunction with client connection policies. In particular, it is now clearer that connections secured with StartTLS are initially considered insecure before the StartTLS operation has been completed and therefore insecure connections must be allowed in order to permit them to submit the StartTLS requests needed to secure them. Issue:DS-9097
Update the Server SDK password storage scheme documentation to indicate that password validators may not always be invoked before the password storage scheme is used to encode the password. As such, the password storage scheme should not make any assumptions about the format of the plaintext passwords it is called upon to encode, nor about whether those plaintext passwords will be allowed for use in the target entry. Issue:DS-9683 SF#:00002043
Improve the performance of certain monitor entry searches that target specific monitor entries by object class. In particular, this includes searches with AND or OR filters, as well as filters that target object classes not defined in the server schema. Issue:DS-9772
Update the LDAP processing within the server to be able to interpret malformed abandon requests sent by versions of the Netscape LDAP SDK for Java built before March 2001. Issue:DS-9865
Lower the severity from SEVERE to MILD for attribute mapping failures due to missing source attribute. Issue:DS-9858 SF#:2068
Fix issue with replication configuration where one replication domain was subordinate to another, LDIF initialization of the subordinate domain could cause replication to diverge in the superior domain for ADD operations. Issue:DS-9607
Fix an issue where the Identity Access API would not return search results when filtering by an operational attribute unless the "attributes" query parameter was also used. Issue:DS-7891
Fix a bug that could interfere with upgrading from a pre-4.1 server when the changelog is enabled. Issue:DS-9873
Deprecate the 'dsreplication detach' command. This command is still functional but will generate warnings if used either interactively or non-interactively. To remove or isolate a server from the replication topology you should instead use 'dsreplication disable', which will remove the server from a replication topology for a given base DN. Issue:DS-9919
Update the server to force data written by the 'backup' and 'export-ldif' tools to disk periodically. This can significantly reduce the impact on response times of update operations that are running on the server by limiting the amount of outstanding data in the file system cache that must be flushed during certain database operations. Issue:DS-9944 SF#:00002092
Update the message emitted by the server when a JVM pause is detected to list additional possible causes beyond garbage collection. Issue:DS-9859
These features were added for version 4.1.0.0 of the Directory Server:
The UnboundID Identity Broker is the first of a new class of components for consumer and subscriber identity management architectures.
As a stand-alone server, it provides authorization decisions for client applications, provisioning systems, API gateways, and analytical tools in any architecture involving personal, account, or sensitive identity data.
Working together with the UnboundID Identity Data Store and Identity Proxy, the Identity Broker is designed to make high-volume and high-speed authorization decisions based on ever-changing consumer profile and consent data. Functionally, the Identity Broker is both the Policy Decision Point and the OAuth2 provider for externalized authorization. Performance-wise, the Identity Broker can support the request volumes driven by the complex, real-time interactions necessary to support today's consumer-facing mobile, social, and cloud ecosystems.
These were known issues at the time of the release of version 4.1.0.0 of the Directory Server:
These issues were resolved with version 4.1.0.0 of the Directory Server:
Update the Directory Server and Directory Proxy Server to provide improved support for LDAP transactions. It is now possible to use batched transactions (either the UnboundID proprietary implementation or standard LDAP transactions as per RFC 5805) through the Directory Proxy Server in both simple and entry-balanced configurations, although only in cases in which all requests may be processed within the same backend server and within the same Berkeley DB JE backend. It is not currently possible to process a transaction that requires changes to be processed across multiple servers or multiple Directory Server backends.
In addition, both the Directory Server and Directory Proxy Server now provide support for a new multi-update extended operation that makes it possible to submit multiple updates in a single request. These updates may be processed either as individual operations or as a single atomic unit. Issues:DS-1096,DS-524 SF#:00001419
SCIM support is now integrated into the Directory and Proxy builds and a separate install of the SCIM extension is no longer required. An initial SCIM HTTP connection handler and SCIM extension is included with the out of the box config but is disabled by default. Issue:DS-6777
Add the ability to create custom SASL mechanism handlers using the Server SDK. This makes it possible for third-party developers to create their own custom authentication logic to better integrate with software that needs to perform a kind of authentication that the server does not support out of the box. Issue:DS-3650
Add support for a new UNBOUNDID-CERTIFICATE-PLUS-PASSWORD SASL mechanism that provides a simple form of multifactor authentication by requiring both a client certificate (supplied during SSL/TLS negotiation) and a password. Issue:DS-4411
Add support for OAuth 2.0 bearer token authentication to the SCIM interface. This requires an OAuthTokenHandler extension built with the UnboundID Server SDK in order to decode and validate bearer tokens. Issue:DS-6763
Add support for a new last access time plugin that can be used to update a ds-last-access-time attribute in an entry that has been targeted by an add, bind, compare, delete, modify, and modify DN operations, as well as search result entries returned to the client. The format of the last login time value can be customized to help avoid updating entries too frequently (e.g., no more than once per day). Issue:DS-7370
Add a generic REST API that can be enabled in the Directory Server or Directory Proxy Server to expose access to raw LDAP data over HTTP using the SCIM protocol. Issue:DS-7267
Make it possible to configure the Directory Server so that some entries may be excluded from the database cache, thereby making it possible to prioritize which entries should be held in memory versus those which require disk access to retrieve.
The selection of entries to exclude from the database cache is performed using an uncached entry criteria object, and the criteria to use may be customized on a per-backend basis. The Directory Server currently includes two forms of criteria: one which uses a filter to indicate which entries should be cached and which should be uncached, and another which uses the last access time to ensure that only recently-accessed entries are cached. The Server SDK has also been updated to make it possible for administrators to define their own uncached entry criteria. Issue:DS-7350
Add support for RPM based installation. Issue:DS-5990
Update the names of the UnboundID-branded products which are now: - Identity Data Store (formerly Directory Server) - Identity Proxy (formerly Proxy Server) - Identity Data Sync Server (formerly Synchronization Server) - Metrics Engine (name unchanged) Issues:DS-7514,DS-7515,DS-7516,DS-7518
Add support for uncached attributes, which can be used to indicate that certain attributes should be stored in a separate database (with different cache settings) from the rest of the content for the entry. This can help administrators better control the memory footprint of the server, particularly in deployments in which the underlying system doesn't have enough memory to fully cache all data.
The server incluedes support for a simple uncached attribute criteria implementation that allows the administrator to specify the attribute types for attributes that should be uncached, optionally restricted to those attributes with at least a minimum number of values or total value size. Server SDK support is also included so that custom uncached attribute criteria implementations can be created using Java or Groovy code. Issue:DS-6617
Add support for a new control that may be used to indicate that updates to certain operational attributes should be suppressed for the associated operation. At present, the control makes it possible to suppress updates to any combination of the following elements:
* An entry's last access time * An entry's lastmod attributes (creatorsName, createTimestamp, modifiersName, modifyTimestamp) * A user's last login time * A user's last login IP address
The ldap-diff tool has been updated to use this control if the server supports it so that it will not require updating the last access time for all entries being examined. Issue:DS-7632
Add a new task (and a corresponding tool to invoke it) that makes it possible to re-encode all or a selected portion of the entries in a local DB backend. This can be useful after a configuration change that impacts the way that entries should be encoded, including:
* If the uncached attribute and/or uncached entry feature has been enabled and you wish to re-encode the entries so that the appropriate portions of the data are uncached.
* If you're using the last access time uncached entry criteria and wish to migrate entries that haven't been accessed in a while to the uncached database.
* If you have enabled or disabled data encryption and/or compression, or if you have changed an encryption key, and want the data to be re-encoded to apply that change.
The set of entries to re-encode may be customized so that entries in specified branches are included or excluded, and/or that entries matching specified filters are included or excluded. It is also possible to exclude entries that are fully and/or partially uncached so that only cached data will be accessed. A rate limiting option can be used to help ensure that re-encode processing will have a minimal impact on other operations handled within the server.
Note that the re-encode processing does not have any impact on the content of the entries (e.g., there are no updates to the lastmod or last access time attributes), nor does it cause the entries to be re-indexed. Issue:DS-7486
Fix a bug where adding a duplicate schema attribute type in a new file would remove the attribute type from the original file on other replicas when the schema change was replicated. Issue:DS-6610 SF#:1736
Add ability to set the maxHeapSize and listenAddress arguments in a properties file when running setup. Issue:DS-6003
Fix a bug where current heap size was not displayed in error message about being too low. Issue:DS-7292
Update the Directory Server to add support for compacting attribute values based on the associated attribute syntax. This can significantly reduce the amount of disk space and memory required to hold values of these attributes.
At present, the server includes support for compacting values of attributes with the following syntaxes:
- Boolean - Distinguished Name - Generalized Time - Name and Optional UID - User Password - UUID
Compaction is enabled by default for all attributes with the Boolean, generalized time, user password, and UUID syntaxes, and the original values should be perfectly preserved by the compaction process.
Distinguished name and name and optional UID compaction will always result in values that are logically equivalent, but the compaction process may introduce some cosmetic differences (e.g., loss of insignificant spaces in between components) that may confuse some clients that expect values to be returned exactly as they were provided, and as such compaction is only enabled by default for the creatorsName and modifersName attributes. In environments in which it is known that clients will accept minor cosmetic differences in DN values, compaction can be easily enabled for all values. Issue:DS-6391
Fix a bug where under certain error conditions the start server scripts could prompt user to overwrite existing file. Issue:DS-7268
Enhance collect support data tool to include directory listings of external replication and changelog database directories. Issue:DS-6943
Fix a bug where dsconfig would exit unexpectedly if going "back" when creating a new property value. Issue:DS-7735
Modify the restore utility to restore the modified timestamp of restored files to have their original value. This makes it possible to do an incremental backup immediately after doing a restore. Issue:DS-8089
Improve Server SDK to allow calling setAttachment on a ProxyOperationContext. Issue:DS-8123 SF#:1876
Upgrade to Berkeley DB Java Edition version 5.0.75 to address a very slow memory leak that is accelerated by having a non-default number of database cleaner threads. Issue:DS-8083 SF#:1867
Eliminate the use of the legacy ds-entry-unique-id, ds-create-time, and ds-update-time attributes, and the virtual attributes used to generate entryUUID, createTimestamp, and modifyTimestamp from them. The server will now generate entryUUID, createTimestamp, and modifyTimestamp as real attributes, and will use syntax-based compaction to provide the same space savings as had previously been accomplished with the legacy compaction mechanism. Issue:DS-6391
Add support for a control that can be included in a delete or modify DN request to indicate that no referential integrity processing should be performed for that operation. Issue:DS-8038
Update the access logging framework to provide support for logging information about replication assurance processing. In the default file-based access logger, RESULT messages may include information about the level of assurance that will be used for the operation, and new ASSURANCE-COMPLETE messages will provide information about the result of that assurance processing. The debug access logger has also been updated to provide detailed information about assurance processing. Issues:DS-7822,DS-7823
Update the Server SDK to make it possible to create custom loggers that include information about replication assurance processing. Issues:DS-7822,DS-7823
Update the server to provide better support for the "binary" attribute option as described in RFC 4522. The server will now automatically ensure that the binary option is provided for attributes with the certificate, certificate list, certificate pair, and supported algorithm syntaxes. The server will now include the binary option when returning attributes of these syntaxes, and will silently insert the binary option if it is missing from these attributes during LDAP add, LDAP modify, and LDIF import processing. Issue:DS-7241
Introduce an "include-thread-id" configuration property on many of the file-based loggers that when enabled adds a threadID field to logging output. This makes it possible to know exactly which thread logged a message, which can simplify correlating errors between log messages and separate logs. This ID can be correlated to a thread name using the cn=JVM Stack Trace,cn=monitor entry. Issue:DS-8212
Update support for batched transactions to fix a potential corner case for a deadlock that could cause the transaction to fail after a timeout period. This change also eliminates the dependency that required all batched transactions to be processed in a pre-specified backend, so that it is now possible to process a batched transaction in any backend (as long as all operations that are in the transaction are in the same backend). Issue:DS-8185
Change stop-*.bat to attempt a soft server shutdown before terminating the process. Issue:DS-408
Eliminate unnecessary thread contention when evaluating ACIs that use groupDN. Issue:DS-8279
Update the server to reduce the need to access uncached data for modify operations targeting partially-cached entries. Previously, modifies to partially-cached entries would always read from and write to both the id2entry and uncached-id2entry databases. Now, the server will attempt to avoid accessing uncached content for modify operations that don't alter uncached attributes. Issue:DS-7899
Update the unique attribute plugin to provide an option to reject changes if they would result in a conflict with a soft-deleted entry. By default, values in soft-deleted entries will not be considered conflicts, but it is now possible to configure the server so that such conflicts will not be allowed. Issue:DS-8239
Fix a bug that prevented the password modify extended operation from updating a user's password when the update was part of an atomic multi-update extended operation. Issue:DS-8217
Fix an issue which could result in a NullPointerException error message when using the Pass Through Authentication plugin with external servers that do not have a location attribute defined. Issue:DS-8265
Update the update tool to run Oracle's DbPreUpgrade_4_1 utility on Data Store database files created with a 4.1 or earlier version of Berkeley DB before being updated to a 5.x version of Berkeley DB. Issue:DS-8135
Update the logic used to generate ds-entry-checksum values so that checksums will be consistent across servers, even if the entries have the attributes or attribute values in different orders. Issue:DS-7754
Update the JMX connection handler to infer an appropriate Java type (e.g. Boolean, Long, Float, Date, or String) for JMX attributes from the underlying LDAP attribute type and value. The legacy behavior to return all JMX attributes as String values can be set if desired through the advanced global configuration property 'jmx-value-behavior'. Issue:DS-7635
Add the --noPropertiesFile option to the status command so that it does not fail when the option is provided to collect-support-data. Issue:DS-8390
Update the CRYPT password storage scheme to support the CRYPT-MD5 encoding offered by a number of Linux and UNIX systems. Issue:DS-8431
Updated the UnsupportedOperationExceptions thrown by the Server SDK to include details about the exceptions that were thrown including the method name and the name and/or Java class of the extension that failed to implement the method. Issue:DS-8421 SF#:1898
These features were added for version 4.0.0.0 of the Directory Server:

The Server SDK has also been updated to make it possible for administrators to define their own uncached entry criteria.
Introduce the Identity Access API, a generic REST API that can be enabled in the Identity Data Store or Identity Proxy to expose access to raw LDAP data over HTTP using the SCIM protocol. For configuration information, please refer to the "Managing the SCIM Servlet Extension" chapter of the Administration Guide. For API documentation, please refer to the UnboundID Identity Access API Client Developer Guide.
Add support for RPM based installation.
Add support for a new last access time plugin that can be used to update a ds-last-access-time attribute in an entry that has been targeted by an add, bind, compare, delete, modify, and modify DN operations, as well as search result entries returned to the client. The format of the last login time value can be customized to help avoid updating entries too frequently (e.g., no more than once per day).

These were known issues at the time of the release of version 4.0.0.0 of the Directory Server:
UnboundID RPMs do not support the "--relocate" option. However, the RPMs are relocatable using the "--prefix" option at install time. Issue:DS-7890
These issues were resolved with version 4.0.0.0 of the Directory Server:
The default "SCIM HTTP Connection Handler" has been replaced by two default HTTP connection handlers, "HTTP Connection Handler" and "HTTPS Connection Handler". They are disabled by default unless the Identity Data Store or Identity Proxy is set up using the setup tool's "--httpPort" or "--httpsPort" options. Issues:DS-7517,DS-7679
File Server HTTP Servlet Extensions now allow a default MIME type to be set with the default-mime-type property. Issue:DS-6959
The SCIM service will now return an HTTP 500 status code instead of a 400 or 404 to the client when the request results in an LDAP result code 52. Issues:DS-7231,DS-7703
To better comply with the SCIM 1.1 specification, the SCIM servlet will now issue a severe warning at startup if SSL is not enabled. Issue:DS-7252
The SCIM servlet now allows HTTP basic authentication to be disabled if OAuth bearer token authentication is enabled. Issue:DS-7264
The default File-Based Access Logger will now log SCIM-initiated LDAP operations by default. These log items will be marked with an 'origin="scim"' attribute. Issue:DS-7472
To comply with the SCIM 1.1 specification, the default scim-resources.xml configuration file now maps SCIM IDs to LDAP entryUUIDs rather than DNs by default. Issue:DS-7478
Fix an issue in which certain password policy and sensitive attribute settings were not enforced if a request originated over an insecure SCIM connection. Issue:DS-7504
The SCIM service will now return an HTTP 400 status code instead of a 500 when a failure occurs during to a sensitive attribute violation. Issue:DS-7703
Fix an issue with the SCIM XMLStreamMarshaller where it did not correctly handle invalid XML characters. Attributes that are not explicitly declared as BINARY in the schema may now be returned as base64-encoded strings if they contain any invalid XML characters. The server will add the "base64Encoded=true" attribute to any XML elements for which this is done, so that the client will know the data is encoded. Issue:DS-7782
Change the stop-* tools to behave like other task based tools. These tools require the use of the --task argument to ensure that user knows they are using a server task. These tools also will not use properties files unless you provide the --usePropertiesFile or --propertiesFilePath arguments.
Fix a performance issue when handling Get Changelog Batch requests with data from replicas that are external to a server's dataset. Issue:DS-7463 SF#:1812
Fix a bug that resulted in extraneous warning messages being seen in tool output. Issue:DS-4533 SF#:1803
Fix a bug that allowed a MODDN operation to use a new RDN with an invalid syntax. Issue:DS-7502 SF#:1814
Audit logging previously logged add, modify, modifydn and delete operations within batched and interactive transactions whether the transaction was successful or aborted. The Identity Data Store now only logs operations performed within a transaction after the transaction has been committed. Issue:DS-7429
Update both the GUI and CLI Directory installers to solicit HTTP/S port information from the user and provide just enough SCIM extension configuration to get the web services running following setup. If the user specifies that they would like HTTP support enabled, setup will configure the HTTP and HTTPS Connection handlers, which are now available in the default configuration out of the box. Afterward, it will perform a search and replace of the scim-resources.xml file, replacing the default dc=example,dc=com base DN with the DN chosen during setup. Finally, it will install the recommended ACIs. Further information is printed regarding additional SCIM setup steps. Issue:DS-7517
Add an option to enable ACI debug traces in the Debug Access Log Publisher. Issue:DS-3322
Update the lastmod plugin so that modifersName and modifyTimestamp will not be updated for operations invoked by the internal root user. Issue:DS-7584
Deprecate support for the large attribute capability, since this capability has been superseded by uncached attribute support. Issue:DS-7369
Fix a bug that prevented viewing hidden and complex configuration properties using dsconfig in a non-interactive mode. Issue:DS-7245
Update the audit logger to provide the ability to exclude information about updates to a specified set of attributes. By default, updates to the ds-last-access-time, ds-pwp-last-login-time, and ds-sync-hist attributes will be suppressed. Information about updates to these attributes will also be suppressed in the LDAP changelog by default. Issue:DS-7584
Improve the performance of ldifmodify when executed with a large source LDIF file. Issue:DS-7656
Fix a bug in the manage-extension tool that would cause an error when attempting to install an extension if that extension's getExtensionDescription method returned null (which is allowed as per the documentation). Issue:DS-7367
Add a Short Unique ID virtual attribute provider that generates short unique identifiers from a sequence number. Each time the virtual attribute is requested for an entry, the sequence number attribute on that entry is incremented and a new unique identifier is returned as the value of the virtual attribute. The short unique identifier is a base62-encoded string containing letters and digits. The short unique identifier incorporates a replica ID to guarantee uniqueness across replication. Issue:DS-7548
Update the dsreplication enable command to correct a server version comparison intended to ensure that the tool may only be used to add a server of the same or newer version in order to prevent configuration incompatibilities between replicating servers. The comparison erroneously failed when attempting to add a server of a newer major version. In order to add a version 4.0 server to a topology containing 3.5 or 3.6 servers, it will be necessary to patch one of the older servers before the 4.0 can be added to the topology using the dsreplication enable command. Issue:DS-7672
Increase the frequency at which search time limits are checked in order to provide more accurate adherence. Issue:DS-7688 SF#:1834
Fix a bug that output low level logging output to console when using dsconfig. Issue:DS-7642
Update dsconfig to allow configuration objects to reference group entries that don't exist (for example in the 'all-included-user-group-dn' property of SimpleConnectionCriteria). This prevents certain errors when running dsconfig in batch mode or when configuring things out of order. Issue:DS-4178
Update the lastmod plugin (responsible for maintaining the creatorsName, createTimestamp, modifiersName, and modifyTimestamp attributes) so that it does not attempt to alter the values of these attributes for replicated operations. The server which initially processed the change will set these attributes and they will continue to be replicated, but there were previously corner cases in which these attributes might not be updated on the source server but would then get set on all downstream replicas, which could lead to their values getting out of sync. Issue:DS-7670
Critical: Improve server stability by disabling explicit garbage collections that were being caused by JMX connections. Issue:DS-7633
Update the import-ldif and rebuild-index tools so that any errors encountered during the index merging phase (e.g., running out of file descriptors) will be more visible to administrators. Also, fix a bug in the rebuild-index tool that could cause an index to be marked trusted even if an error occurred during the index merging phase that made the index untrustworthy. Issue:DS-7363
Fix a bug in the LDAPConnectionHandler where it did not close the NIO Selector on shutdown. On some platforms this caused the underlying socket channel to remain bound, which prevented the server from being able to restart. Issue:DS-7373
Update the backend finalization code so that it can now make multiple attempts to close a database. This may help the backend shut down cleanly if the first attempt at closing a database fails because one or more long-running operations are still accessing that database (e.g., holding a cursor open). Issue:DS-7746
These features were added for version 3.6.0.0 of the Directory Server:
Update the Directory Server and Directory Proxy Server to provide improved support for LDAP transactions. It is now possible to use batched transactions (either the UnboundID proprietary implementation or standard LDAP transactions as per RFC 5805) through the Directory Proxy Server in both simple and entry-balanced configurations, although only in cases in which all requests may be processed within the same backend server and within the same Berkeley DB JE backend. It is not currently possible to process a transaction that requires changes to be processed across multiple servers or multiple Directory Server backends.
In addition, both the Directory Server and Directory Proxy Server now provide support for a new multi-update extended operation that makes it possible to submit multiple updates in a single request. These updates may be processed either as individual operations or as a single atomic unit.
SCIM 1.1 support is now integrated into the Directory Server and Directory Proxy Server, and a separate install of the SCIM extension is no longer required. An initial SCIM HTTP connection handler and SCIM HTTP servlet extension is included with the out of the box config but is disabled by default.
Add support for the PATCH operation in the SCIM SDK and server implementation. This allows for resources to be partially updated without having to send the entire contents of the resource across the network, reducing network and processing overhead. This is especially beneficial for resources with many attributes, such as Groups.
Add support for OAuth 2.0 bearer token authentication to the SCIM interface. This requires an OAuthTokenHandler extension built with the UnboundID Server SDK in order to decode and validate bearer tokens.
Add support for a new UNBOUNDID-CERTIFICATE-PLUS-PASSWORD SASL mechanism that provides a simple form of multifactor authentication by requiring both a client certificate (supplied during SSL/TLS negotiation) and a password.
Add the ability to create custom SASL mechanism handlers using the Server SDK. This makes it possible for third-party developers to create their own custom authentication logic to better integrate with software that needs to perform a kind of authentication that the server does not support out of the box.
IPv6 is now a supported deployment option.
64-bit JDK 7 is now a supported deployment option, but 32-bit JDKs are no longer supported.
These were known issues at the time of the release of version 3.6.0.0 of the Directory Server:
When reinitializing replication for a directory server, it is important not to disable and re-enable replication. If replication is ever disabled for a replica, then the cleanup-local-server command must be run before replication is re-enabled. Issue:3159
Support for the SCIM protocol is now built in to the server. A disabled HTTP Connection Handler called "SCIM HTTP Connection Handler" and an HTTP Servlet Extension called "SCIM" will be added to the configuration during the update process; to prevent upgrade conflicts, any existing Server SDK-based SCIM extensions should be uninstalled prior to running update. Issue:DS-7324
These issues were resolved with version 3.6.0.0 of the Directory Server:
Fix an issue where modifications to attributes with options were not recorded correctly in the LDAP changelog nor in the recent changes database of the Local DB Backend. Issue:DS-6753
Change the installer to use Large Pages when testing available memory if the OS is configured to use Large Pages. Issue:DS-6760 SF#:1745
Update the replica code to never perform a search using the ds-sync-hist attribute on backends using the Berkeley DB database. Update error messages to better reflect severity and to omit reference to num-recent-changes on non-Berkeley DB backends. Issue:DS-6744
Update the JMX Connection Handler configuration to issue a warning if it is enabled. On some JVMs, enabling this aspect of JMX can lead to long garbage collection pauses. Issue:DS-6832
Fix a bug that prevented search requests for attributes with specific options from not returning all of the intended results. Issue:DS-6944 SF#:1765
Update the ChangelogBackend to filter by ChangeType early in the examination process (before decoding the full ChangeLogEntry), for better efficiency. Update the ChangelogBackend to use the current thread to read each ChangelogEntry if a GetChangelogBatch request is only interested in a sparse subset of the changes available. This will reduce contention when processing lots of these requests. Issues:DS-6911,DS-6912
Add help text to web console deployment descriptor with JBoss compatibility tips. Issue:DS-6976 SF#:1749
Update the logic that the server and its associated tools use to select the SSL/TLS protocol version for secure communication to provide the best combination of security and compatibility. Also, a new log message type is available that can provide information about the negotiated security protocol, including the selected SSL/TLS protocol version and cipher suite. Issues:DS-6720,DS-6903
Upgrade the directory server to use version 5.0.58 of Berkeley DB Java Edition. Issue:DS-6935
Provide a secondary database storage format for attribute indexes that can be more efficient for writes. A new advanced property exploded-index-entry-threshold allows index keys with high entry counts to be written to a separate database in an exploded format. The exploded format stores each entry ID independently in its own record, so does not require the entire set of entry IDs for a key to be rewritten on each update.
An index statistics summary table is now output after an LDIF import or index rebuild, to aid in tuning the index configuration.
A new property substring-index-entry-limit allows substring indexes to have their index-entry-limit value set independently from other types of index for the same attribute. Issue:DS-5864
Update the Directory Server to fix a bug that prevented the simple paged results control from being handled properly for searches spanning multiple backends. Issue:DS-5953
Fix a race condition bug that could result in replication thread crashes when replicas are slow to respond with monitoring data. Issue:DS-6994 SF#:1782
Replace the move-entry tool with a new move-subtree tool. The move-subtree tool provides all of the capabilities of the move-entry tool, but also adds the ability to move entire subtrees (ideally with a relatively small number of entries, since both the source and target servers hold locks during the move). Issue:DS-6035
Prevent failures for configuration group changes where the parent configuration entry may or may not exist amongst the various servers in the configuration group. Issue:DS-6088
Fix an issue where a replica restored from backup may not receive some changes that have been applied after the backup was taken. Issue:DS-6812
Add support for a new set subtree accessibility extended operation that can be used to make a specified subtree either read-only or hidden. Issue:DS-7028
Update the Directory Server to not issue a work-queue-backlogged alert after doing an explicitly invoked garbage collection. Issue:DS-3320
Update the Server SDK to provide support for developing custom account status notification handlers (which may be used to take action like notifying users and/or administrators of significant password policy or account state events) using Java or Groovy. Issue:DS-3651
Add support for a new extended operation that can be used to retrieve information about all subtree accessibility restrictions defined in the server. Issue:DS-7029
Allow a soft-deleted entry to be moved by the move-subtree command line tool. Issue:DS-6592
Address a server performance degradation when the separate-monitor-entry-per-tracked-application property of Processing Time Histogram Plugin was set to true. Issue:DS-7045
Fix an issue in the migrate-ldap-schema tool where the --trustStorePath argument did not work. Issue:DS-5924
Fix a bug where the PermissiveModifyRequestControl was not honored in conjunction with the objectClass attribute. Issue:DS-7046
Fix the manage-tasks tool so that it does not use an insecure connection when --useStartTLS is specified, and does not prompt for certificate trust when --trustAll is specified. Issue:DS-5924
Fix an issue where an attempt to proxy as another user incorrectly failed with insufficient access rights. This only occurred when a search operation spanned multiple database backends in the Directory Server. Issue:DS-6372
Changed the default replication domain and server window sizes to 5000 since this leads to improved performance in some situations. Issue:DS-7229
Add the --isCompressed option to the parallel-update tool so that it can read input LDIF files that are gzip compressed. Issue:DS-7237
Fix a problem in the manage-extension tool where it would fail on Windows because it tried to delete some temp files that were currently in use. Issue:DS-6770
Add a new subtree-accessibility tool that can be used to make a subtree hidden or read-only, or to revert it back to its normal accessibility state.
Fix a bug in which the Directory Server may return an incorrect referral if it encounters an LDAP URL with a scheme of "ldaps" rather than "ldap". Issue:DS-7246
Update the active operations monitor entry so that information about active search operations will include "unindexed=true" for searches known to be unindexed. Issue:DS-5904
Fix a bug in dsconfig that prevented going back when adding a new configuration object inside of an existing one. Issue:DS-7263 SF#:1793
Add a new "examples-of-all-tags.template" make-ldif template that demonstrates and explains the use of all variations of all supported tags. This template isn't intended to actually be used to generate entries, but merely to document the available tags. Issue:DS-5947
Update the dsreplication tool to fix the --noPropertiesFile option which was previously ignored. Issue:DS-7319
Update the Directory Server to acquire an exclusive lock in the backend while processing changes for a batched transaction or atomic multi-update operation. This can help prevent other clients from performing operations which may result in conflicts with those operations that are part of the transaction. Issue:DS-7235
Fix a bug that could cause an error during server startup if the root DSE backend was configured with an explicit set of subordinate base DNs. Issue:DS-7325
Fix a bug in which a successful bind using a password-based SASL mechanism would not clear the record of previous authentication failures for the account. Issues:DS-7387,DS-7388
Fix an issue where the Directory Server reported inaccurate and fluctuating values of estimatedChangesRemaining in the access log for changelog batch requests. This was evident when the Sync Server in notification node was configured to detect changes through a Proxy Server with entry-balancing across the Directory Servers. Issue:DS-7355
Critical: Fix a bug in the LDAP Changelog where the changelog index manager could capture new changes for an attribute in one index after already hitting the end of another index. This created the possibility for changes to be missed when processing get-changelog-batch-requests at the same time that live traffic is happening. Issue:DS-7422
These features were added for version 3.5.1.0 of the Directory Server:
The Metrics Engine is a core server product that collects and aggregates key diagnostic, capacity, and usage information from an UnboundID server topology consisting of instrumented Directory Server, Directory Proxy Server, and Synchronization Servers running release 3.5.0.0 and above. Metrics data can be explored and graphed using the included query-metric tool, and the Metrics Engine REST API makes this information available to custom applications and third-party systems. To learn more about the Metrics Engine, please refer to the UnboundID Metrics Engine Administration Guide.
These were known issues at the time of the release of version 3.5.1.0 of the Directory Server:

Fix a bug that prevented search requests for attributes with specific options from not returning all of the intended results. Issue:DS-6944 SF#:1765
Add help text to web console deployment descriptor with JBoss compatibility tips. Issue:DS-6976 SF#:1749
Fix a race condition bug that could result in replication thread crashes when replicas are slow to respond with monitoring data. Issue:DS-6994 SF#:1782
These features were added for version 3.5.0.0 of the Directory Server:
WAN-Friendly Replication
Replicated Directory Servers are often deployed at multiple data centers. In order to reduce WAN traffic between data centers, Directory Servers no longer propagate updates to all other Directory Servers directly. Instead, a Directory Server is automatically selected in each data center to handle update messages to and from remote data centers. For more information, see the WAN-Friendly Replication section in the Managing Replication chapter of the Directory Server Administration Guide.
Soft Deletes
The Directory Server now supports the ability to retain an entry after the delete operation. Instead of performing a permanent delete of an entry, a delete request with the Soft Delete Request control causes an entry to be renamed and hidden from subsequent searches. An entry preserved in the deleted state is known as a soft-deleted entry and may be undeleted at a later time. Users with the soft-delete-read privilege and access to the Soft Delete Entry Access Control may search for soft-deleted entries or non-deleted and soft-deleted entries. Soft-deleted entries are undeleted when an Add request with the Undelete control and the ds-undelete-from-dn attribute is processed.
Features:
The ldapsearch tool supports an --includeSoftDeletedEntries option, which causes soft-deleted entries to be included in search results. This option takes one of the following values: with-non-deleted-entries (default), without-non-deleted-entries, and deleted-entries-in-undeleted-form.
The ldapmodify tool supports an --allowUndeletes argument which treats selective changetype: add ldif entries with the ds-undelete-from-dn attribute as an undelete.
Password policy objects may now be stored in the Directory rather than in the configuration backend. For example, an organization may need to delegate administration of password policies without granting Directory Administrator privileges or configuration-write privileges to an organization administrator. Password policies may be stored relative to the members of an organization, e.g. "cn=Organization Password Policy,cn=Password Policies,cn=config,o=Acme,ou=organizations,dc=example,dc=com" allowing for configuration of a virtual attribute provider specifying the password policy for organization members using the ds-pwp-password-policy-dn attribute. Presently dsconfig only creates password policies in the Directory Server configuration; to create, update or delete password policies in the Directory, password policy entries may be managed with the ldapmodify command.
The static group cache has been enhanced to improved nested static group performance. Support for nested static groups is now always enabled, and the setting for the support-nested-groups property of the Static Group Implementation configuration object no longer applies. However, to support nesting of dynamic groups inside static groups, the cache-user-to-group-mappings property is now disabled.
The isMemberOf virtual attribute can now be configured to only include a user's direct memberships (i.e., not dynamically derived and/or not through nested groups) using the new direct-memberships-only property. The new isDirectMemberOf virtual attribute, which is disabled by default, may also be used for this purpose.
Server SDK extension bundles may now be installed and updated using the manage-extension tool. For information about using the tool and building and packaging extensions, please refer to the UnboundID Server SDK documentation.
The server now includes an HTTP Connection Handler that can be used to provide HTTP access to the server. An HTTP Connection Handler can be configured to reference either an HTTP Servlet Extension written with the Server SDK or a standard web application (via a Web Application Extension configuration object). For more information, please refer to the Configuring HTTP Access for the Directory Server section of the Configuring the Server chapter in the UnboundID Directory Server Administration Guide.
These were known issues at the time of the release of version 3.5.0.0 of the Directory Server:
With Sun Java version 1.6.0_21 through 24, there is a known issue with frequent, long garbage collection pauses. To avoid these, we recommend using version 1.6.0_25 or higher of the JVM where this issue has been addressed.
When reinitializing replication for a directory server, it is important not to disable and re-enable replication. If replication is ever disabled for a replica, then the cleanup-local-server command must be run before replication is re-enabled. Issue:3159
When using a GSSAPI SASL Mechanism Handler the kerberos-service-principal property is only used to determine the protocol (i.e. "ldap"). The hostname will always be determined using the server-fqdn property. Issue:DS-5053
The move-entry tool cannot currently be used to move a soft-deleted entry, as the server disallows external attempts to add an entry with the ds-soft-delete-entry object class. Issue:DS-6592
When a large number of virtual static groups exist, retrieving the membership of a virtual static group may be more expensive than in versions prior to 3.5.0.0. Issue:DS-6842
A case exists where the re-initialization of a replica via the binary copy method may result in missed changes. When a replica is to be re-initialized, it is recommended that it not receive write requests directly from clients after the point in time when the backup was taken on the source server. Issue:DS-6812
These issues were resolved with version 3.5.0.0 of the Directory Server:
Fix an issue where multiple server configuration changes would fail if any of the servers were configured with an LDAPS (SSL) connection handler. Issue:DS-5100
In some cases, replication used not to delay the startup of the server even if the backlog was above the configured startup threshold. Issue:DS-5194
Fix the LastMod Plugin and the Changelog Backend so that the 'modifiersName' attribute will get correctly replicated and show up on changelog entries as the DN of the user who last modified the entry, for all operation types including DELETE. Issue:DS-4171
Fix a bug with replication backlog alert where a unlimited threshold would always result in an alert being sent. Issue:DS-3337
Add support for properties file usage with summarize-config Issue:DS-5213
Update the collect-support-data tool to include the equivalent of jstack output for IBM VMs on non-AIX platforms. Issue:MON-5027
Improve the communication between Replicas and Replication Server in the same process to use direct communication instead of network sockets. Issue:DS-3308
Improve OID syntax checking in ACIs Issue:DS-3323
Add the ability to specify a reason when entering and leaving lockdown mode. This is recorded in the logs and in the alerts that are generated. Issue:DS-5331
Update the Subject Attribute to User Attribute Certificate Mapper so that duplicate mappings are not allowed for the same certificate attribute. Issue:DS-5547
Fix a bug where replication conflict entries were being filtered from search results, but counted towards the size limit. Issue:DS-5405 SF#:1604
Update the server to provide the ability to customize the client connection policy that is used for internal operations. Previously, the server would always use an internal policy that only knows about local backends, but in the Directory Proxy Server, this could prevent internal operations from accessing content in backend servers.
The Server SDK has also been updated to provide ClientContext and OperationContext methods that make it possible to get internal connections using either the server's configured default internal client connection policy or the policy associated with the client connection on which the request was received. Issue:DS-5553
Fix a bug that could cause the server to pass the old configuration into the isConfigurationChangeAcceptable method for a number of types of Server SDK extensions. Issue:DS-5597
Update the server to support tracking LDAP operation processing statistics on a per application basis. Applications are identified using Connection Criteria referenced from the tracked-application property of the Global Configuration. The Processing Time Histogram Plugin and Periodic Stats Logger Plugin include settings to control whether per-application statistics are exposed in the monitor and logged to CSV files. Issues:DS-270,DS-5241
Update the Server SDK to provide extensions a way to dynamically register their own monitor providers with the server, without requiring any server-side configuration objects. Issue:DS-5271
Fix a bug where virtual attributes were not being pared from changelog in the same way as non-virtual attributes Issue:DS-5608 SF#:1629
Fix a bug where access logger was not using the include-add-attribute-names property correctly Issue:DS-5549 SF#:1612
Fix an issue with the FIFO Entry Cache where under high load, improper thread synchronization could lead to an entry in the cache being corrupted. Issue:DS-5659 SF#:00001632
Remove support for configuring multiple base DNs during install. Secondary Base DNs can still be added after running setup as needed. Issue:DS-808
Improve replication change management Issues:DS-5108,DS-5572
Add workaround in SSL processing to detect potential buffer underflow or renegotiation even when processing appears to be OK. Issue:DS-5748 SF#:1636
Fix a bug where method level debug tracing could cause extraneous logging from other methods in the same class. Issue:DS-5760 SF#:1636
collect-support-data now excludes binary files unless --includeBinaryFiles is specified. Issue:DS-4260
Address an issue where search index processing would examine more entries than necessary when executing AND searches that included fully-indexed, complex components, such as (&(app=X)(|(priv=A)(priv=B))). Issue:DS-5783
Add system time change detection for backwards jumps in system time. Issue:DS-710
Fix a bug where rotate log files were being included in collect-support-data archive if they were compressed. Issue:DS-5745
Add a new servlet extension that can be used to serve static content like HTML pages, images, or other kinds of files. Issue:DS-5827
Add support for a new UNBOUNDID-TOTP SASL mechanism that uses the time-based one-time password mechanism as described in RFC 6238. This mechanism uses a base32-encoded shared secret stored in the user entry in conjunction with the current time to generate a temporary password that may be used during the authentication process. The one-time password may also be used in conjunction with a static password (e.g., as stored in the userPassword attribute) for a form of multifactor authentication which requires both knowledge of that static password and a device capable of generating the appropriate one-time password.
The Google Authenticator app (which is available for Android, iOS, and Blackbery devices) supports TOTP and can be used to generate the generate the appropriate one-time password. The UnboundID LDAP SDK for Java has also been updated with support for generating TOTP passwords, and includes support for the UNBOUNDID-TOTP SASL mechanism. Issue:DS-5852
Fix a bug where a replica unexpectedly leaving the replication topology may cause one or more servers to become out-of-sync. Issue:DS-5862
Fix an issue where DirectoryThreads did not set their context classloader to the one provided by our ClassLoaderProvider. This caused all the threads in the server to use the system classloader by default, which only has access to the classes specified on the classpath (i.e the core server libraries under the /lib directory). This becomes problematic if one of these threads calls into a library that uses Thread.getContextClassLoader() to load a class that is outside of the core server libraries (for example in an extension library). In this case it would use the system classloader and subsequently throw a NoClassDefError. Issue:DS-5876
Fix a bug where the dsreplication enable subcommand may could to initialize the server registry when enabling replication between islands of servers already replicating. Issue:DS-5881
Update Berkeley DB to version 5.0.34. This version uses an updated on-disk database format that is not backwards compatible with the previous versions. Any existing databases using the previous format will be automatically updated when the server is started. Issue:DS-5657
Update the HTTPConnectionHandler to use Jetty version 8.1.0, which fixes several problems in the IO layer with respect to the latest JVMs and browsers. Switch the configuration to use Jetty's more efficient NIO socket connectors instead of the traditional blocking socket connectors. Issues:DS-5622,DS-5900
Prevent modification operation failures against replication conflict entries when the entry is already a replication conflict entry. Issue:DS-5601
Add a monitor entry (cn=Group Cache,cn=monitor) for the group cache that contains statistics for all the group implementations. Issue:DS-4728
The changelog backend will now index all modified user attributes by default. Previously, no attributes are indexed by default. Users who have changed the index-include-attribute configuration parameter from its previous default value may need to make additional changes after an upgrade. Issue:DS-5002
Add a new property override-local-password to the Pass Through Authentication Plugin so that with the default value of false, it will only attempt the bind remotely if and only if the local bind fails because there is not a local password defined. When set to true, it will attempt the bind remotely if the local bind fails for any reason.
The new override-local-password property changes the default behaviour of the Pass Through Authentication Plugin. To restore the previous behaviour, change the value to true. Issue:DS-5766
Add fix to handle SSL/TLS renegotiation attempts during secure communication. Issue:DS-5965
The dsreplication status command line does not display the replication server status table by default, only the replica table. The --displayServerTable argument may be used to display the server status table as well. The Age of Oldest Backlog Change, the Generation ID and the Replication Server ID columns are no longer displayed by default. The --showAll argument may be used to display these fields as well. Location, WAN Gateway Priority and Recent Change Rate are new columns shown in their respective tables. The new --location argument allows restricting the status report to servers and replicas in the specified location(s) only. Servers in the displayed tables are now sorted by location first and then by hostname/port number. Issue:DS-5341
Fix a problem where the collect-support-data tool could timeout when connecting over SSL, or prompt the user to verify the server certificate even when the --no-prompt argument was specified. Issue:DS-4823
Changes to the location property in the global configuration now require a server restart. Issue:DS-5901
Add safety measures for replication detach: Detaching will now set the writability of the Backends to internal-only; Enabling will warn when Backends have limited writability and fail if backend is read-only. Issue:DS-5301
The userPassword and authPassword attributes are now excluded from returned entries for enhanced security. This is currently implemented with a new default global ACI that denies read, search, and compare access to the attributes instead of the sensitive attributes feature for backwards compatibility. Root users will still be able to view the password attributes over LDAP. Please refer to the documentation for how to fully protect the password attributes by using a global sensitive attributes configuration instead. Issue:DS-3641
Fix a bug that caused many command-line tools to output to stderr rather than stdout. Existing scripts that depend on the old behavior may need to be modified in order to continue working correctly. Issues:DS-3610,DS-4195
Fix a bug with DN decoding from strings with special characters to ensure that the changelog will store a valid DN for the targetDN even if the original entry's DN was not properly escaped. Issue:DS-6061 SF#:1679
Update the file format used by "dsconfig --batch-file" to support using '\' as a line continuation character. If the last character on a line is a '\', then it will be removed and the following line concatenated on to it. Issue:DS-635
Remove the "Custom" type from the list when creating new objects in dsconfig. This was often confused with the "Third-Party" and "Groovy Scripted" types when users intended to create a Server SDK extension. Issue:DS-5229
Assigned NO-USER-MODIFICATION to the following directoryOperation attributes:
ds-sync-conflict changelog-add-entry changelog-deleted-entry changelog-modify-changes compact-after-values compact-before-values compact-entry-key-attrs ds-private-naming-contexts ds-pwp-auth-failure ds-pwp-last-login-time ds-pwp-password-changed-by-required-time ds-pwp-reset-time ds-pwp-warned-time pwdReset
There attributes will no longer be modifiable over LDAP.
dsreplication cleanup-local-server subcommand will no longer generate a cleanup-backends.ldif file to remove the replication related attributes from the backend. Instead, the user needs to rely on import/export to clean affected backends. Issue:DS-4718
Update ldap-diff to use the schema of the target server when comparing entries. This enables comparing entries whose DN's include case-sensitive components. Issues:DS-2748,DS-6197
Update the replication code to handle port checks from the dsreplication command line utility. This prevents the server from logging SSL connection attempt failures. Issue:DS-6190
Ensure that critical and unsupported controls using a virtual attribute filter will fail since they are not supported in tandem. Issue:DS-6244 SF#:1694
A new property named obscure-attribute on the audit logger allows specified attributes to have their values obscured in the audit log. The default setting for the Proxy Server is to obscure the userPassword and authPassword values. Each value of an obscured attribute is replaced in the audit log with a string of the form "***** OBSCURED VALUE *****". The default setting for Directory Server is not to obscure any attributes, since the values of password attributes appear in hashed form rather than in the clear. Issue:DS-5278
Introduce a global property "ds-cfg-use-compact-sync-hist" that when enabled, will not encode historical single-valued attribute values if they are the same as the current value of the attribute for add and repl change types. This encoding will not be backwards compatible and all historical data must be flushed before reverting back to a previous version by exporting the replicated base DN without the ds-sync-hist attribute and re-importing the data. Issue:DS-6055
Fix a bug that prevented proxied authorization from working as expected during a search that crosses into a secondary backend. Issue:DS-6171 SF#:1686
Critical: Fix a bug that allows users with expired passwords to change attributes in their own entry other than password. Issue:DS-6054
Modify the ldap-diff tool to add LDAP connection options for SSL, StartTLS, and SASL authentication. Issue:DS-6034
Update the status tool to fix an issue in the tool may fail to connect to the server to retrieve some status information when the --no-prompt option is specified. Issue:DS-5989
Update the Server SDK to make it possible to create an internal connection that behaves like an external connection and is subject to its constraints. Issue:DS-5851
Fix an issue with dsreplication remove-defunct-server where removing one of many servers configured with SSL could result in the wrong server being removed from the ADS. Issue:DS-6193
Add support for a number of operational attributes which can be added to user entries in order to restrict who those users can proxy as when using proxied authorization, in addition to enhancing existing operational attributes tha can be used to restrict who a user can be proxied as. The complete list of attributes and intended use is as follows:
Fix a bug that prevented ACIs with a targetFilter from working properly with search operations with an entryUUID filter. Issue:DS-6102 SF#:1668
Nesting dynamic groups inside static groups are now always supported. The static group cache is now always enabled and the cache-user-to-group-mappings configuration property is no longer maintained. Issue:DS-6272
Fix the Directory Server code so that the a replicated server correctly determines when updates only from a single server should be accepted at startup. Issue:DS-5980
Update the Synchronization Server to make sure it merges remote state from all other servers at least once before letting the sync pipes begin. This eliminates a very small window that could only happen at startup, where a Synchronization Server could take over the master status and begin syncing before it has merged any remote state from secondary Synchronization Servers.
Update the Synchronization Server to handle a network partition between redundant instances. This guarantees that the true master will incorporate state from the other master(s) after the network is restored.
Fix a bug in the LDAP changelog where it would not incorporate GetChangelogBatch token information about other replicas in a certain edge-case scenario. Issues:DS-4520,DS-6320,DS-6340
Fix a bug that prevented overlapping binds from succeeding when used with a client connection policy that has request criteria containing connection required tied to a specific bind user. Issue:DS-6432 SF#:1717
Enable the capturing of DBPrintLog information for each BDB JE Backend to the collect-support-data archive. Issue:DS-6075
Fix an issue where out-of-the-box server required more memory than it should have, because of how the DictionaryPasswordValidator stored its word dictionary. The memory usage has been reduced by roughly 35MB. Issue:DS-6040
Compact encoding of historical attribute values is now enabled by default. This encoding will not be backwards compatible and all historical data must be flushed before reverting back to a previous version by exporting the replicated base DN without the ds-sync-hist attribute and re-importing the data. Issue:DS-6284
The dsreplication initialize-all subcommand has been updated to allow more time for the destination replicas to complete the import process. Issue:DS-6437
Update the dsreplication enable subcommand to prevent adding a server using a prior version into the topology. In mixed version environments, dsreplication enable may only be executed from an instance running the older version of the product. Issue:DS-6060
Update Berkeley DB to version 5.0.48. This version uses an updated on-disk database format that is not backwards compatible with the previous versions. Any existing databases using the previous format will be automatically updated when the server is started. Issue:DS-6202
Updated the server to support hosting of standard web applications using the HTTP Connection Handler. Issue:MON-754
Fix a bug that prevented collect-support-data from using the bindPasswordFile argument. Issue:DS-6402 SF#:1719
Fix an issue which caused extremely poor import-ldif performance when a VLV index was configured. Issue:DS-5712
Provide better monitoring of group cache memory usage by adding "current-cache-used-bytes" and "current-cache-used-as-percentage-of-max-heap" attributes to the Group Cache monitor provider. Also add "memory-consumer" attribute to the JVM Memory Usage monitor provider to provide usage summary of all registered memory consumers. Issue:DS-6482
Log a warning when two or more HTTP Servlet Extensions are configured to use exactly the same servlet context path. Issue:DS-5739
Update the LDAP Changelog monitor entry to have a unique object class: ds-changelog-backend-monitor-entry. Issue:DS-5059
Provide more monitoring for the LDAP Changelog backend especially for GetChangelogBatch request processing expose monitoring information for this backend in the Periodic Stats Logger. Issue:DS-5700
Improve performance of retrieving changes from the LDAP Changelog using the GetChangelogBatch request by reducing changelog entry processing for entries that are excluded by base DN. Issue:DS-5701
Provide config options to smooth out database delete operations during LDAP changelog purging to reduce impact on server throughput and response time. Issue:DS-5724
Critical: Address an issue where a directory server might resend duplicate changes when processing a GetChangelogBatch request in an environment that is under heavy load. Issue:DS-5656
Expose replication changelog database monitoring information in cn=monitor and the Periodic Stats Logger Plugin. Issue:DS-5723
Provide Directory Server and Proxy Server support for GetChangelogBatch options to control whether to return changes for modify or delete of soft-deleted entries. Issue:DS-6362
Critical: Update the Directory Server to apply access controls when processing the GetAuthorizationEntryRequestControl. Issue:DS-854
Fix an issue where replicas could diverge in the event of a conflict between two undelete operations on a soft-deleted entry to two different DNs. Issue:DS-6407
Fix a bug that prevented collect-support-data from running the status command successfully when the trustStorePath argument was provided. Issue:DS-6311
Add support for soft deletes and undeletes to parallel-update. Issue:DS-6408
Added full directory listing to collect-support-data for files relocated outside of the server root. Issue:DS-6289
Provide an argument to the setup tool to configure the server to automatically include verbose garbage collection output in the server.out log file. Issue:DS-5681
The server no longer attempts to execute tasks at startup which are in the RUNNING state. Such tasks could exist if they were running when the server was killed or otherwise terminated abruptly. Issue:DS-5710
Monitor the available disk space in the backup directory during a backup of local DB backends, the changelog backend and the replication backend. If disk space gets too low, the backup is cancelled and all individual backend backups that were created during this backup are removed. The server now sends an alert for any individual backend backup that fails during an online backup. Issues:DS-6353,DS-6601
Fix an issue where rebuild-index only rebuilt the first VLV index when a second VLV index had a common prefix in its name. Issue:DS-5645
On Linux, the server and its tools now attempt to raise the limit on maximum user processes to 16,383 if the current value reported by ulimit is less than that. This is because Linux counts a thread as a user process, and some recent Linux distributions have a very low default value for max user processes. Issue:DS-6410
Update dsconfig so that inclusion of the --advanced option will list expert-level objects. Issue:DS-6652
Fix an issue where the Directory Server could truncate the resume token when processing a GetChangelogBatchExtendedRequest, which could cause downstream errors in clients such as the Synchronization Server. Issue:DS-6655 SF#:1733
Provide better validation of the file-based key manager provider configuration. In particular, the key manager provider now rejects a configuration where the keystore cannot be loaded using the provided PIN. The Directory Server will no longer start if an LDAP connection handler (with security enabled) references an incorrectly configured key manager provider. Issue:DS-6512
Fix an issue with import-ldif where it could fail when specifying --includeBranch on backend with base DN subordinate to another backend base DN. Issue:DS-3038
Update Berkeley DB to version 5.0.55. Issue:DS-6680
Provide additional properties in Simple Result Criteria that match against the authorization user (originating user) of the operation, similar to properties in Simple Connection Criteria that match against the authenticated user. The authorization user is often the same as the user authenticated on the connection but not when the operation has come through a proxy server. Issue:DS-6505
Improve the prompt that is displayed by command-line tools when establishing a secure connection to a server when no trust manager was specified and the server certificate should not be automatically trusted. The information is formatted more neatly, and the prompt will now include MD5 and SHA-1 versions of the certificate fingerprint and information about the issuer certificate chain if appropriate. There will also be an additional warning if the certificate is self signed. Issue:DS-5127
Update tools that can perform LDAP SASL authentication to add support for the UNBOUNDID-TOTP SASL mechanism that can be used for multifactor authentication. Issue:DS-6676
Update the LDAP connection handler so that any attempt to explicitly configure the allowed SSL protocols and/or cipher suites will be validated before being put into service. Any attempt to use an unsupported protocol or cipher suite will be rejected with an error message including the acceptable values. Issue:DS-6663
Fix a bug that prevented setup from using external keystore and truststore PIN files in the final installation's configuration. Issue:DS-6516
Update the ldifsearch tool so that it will no longer report errors for entries that violate the server schema by default. This behavior can be restored using the new --checkSchema option. Also, update the ldifmodify tool to provide better schema checking by default, and to add a --noSchemaCheck option that allows it to work with LDIF files and change sets that violate schema constraints. Issue:DS-4326
Fix a bug in the passthrough authentication plugin that could cause its initialization to fail if any of the target servers is unavailable. Issue:DS-5746
Fix a bug where groups with a multi-valued DN were not being escaped properly. Issue:DS-6732 SF#:1746
Add a new LDAP URL attribute syntax and modify the memberURL and ref attribute types to use it instead of their previous directory string and IA5 string syntaxes. By default, the LDAP URL syntax will ensure that only valid LDAP URLs can be assigned to an attribute with that syntax, which prevents errant behavior resulting from malformed LDAP URLs. However, it is possible to alter the configuration for the attribute syntax so that any arbitrary string is allowed if that capability is needed.
Note that if you are upgrading a Directory Server instance with existing data, and if that data contains entries which have memberURL or ref attributes with values that are not valid LDAP URLs, then attempts to modify those entries may fail as a result of those malformed values. If your existing data includes malformed memberURL or ref values, then you will either need to correct those values so that they are valid LDAP URLs, or you will need to reconfigure the LDAP URL attribute syntax so that it does not require strict adherence to the LDAP URL format. Issue:DS-6491
Modify the global configuration so that by default the server will allow no more than ten concurrent unindexed searches, rather than the previous default which did not enforce any such limit. This will help prevent the server from becoming unresponsive if too many clients issue unindexed search requests. Issue:DS-6735
Update the connection handler monitor entry so that listeners without an explicit listen address will be reported as "*:port" rather than just ":port". This helps prevent the listen address value from requiring base64 encoding in LDIF form. Issue:DS-6714
Introduce automatic purging of soft-deleted entries. The soft-delete policy can be configured to purge the oldest soft-deleted entries by retention time and/or the number of soft-deleted entries to be retained. Issue:DS-6400
Enhance the way setup handles security arguments to ensure server is configured properly. Issue:DS-6514
Add a new extended operation handler that may be used to validate a TOTP (time-based one-time password) without performing authentication. This can help add additional assurance about the identity of a user that has already been authenticated. Issue:DS-6748
Fix a bug that could cause idle account lockout to be enforced even if last login time tracking is not enabled. In addition, when changing the server's idle account lockout configuration, administrative tools will also warn about ensuring that last login time tracking has been enabled for a period of time to ensure that user accounts have been populated with the necessary state information. Issue:DS-6679
Add a new WebAppServerContext interface to the Server SDK, which can be used by web applications running in the server to interact with the server by doing things like invoking internal operations, registering change listeners and monitor providers, performing logging and debugging, and generating administrative alerts. The new WebAppServerContextFactory class may be used to obtain a server context instance. Issue:DS-6723
Fix an issue where modifications to attributes with options were not recorded correctly in the LDAP changelog nor in the recent changes database of the Local DB Backend. Issue:DS-6753
Change the installer to use Large Pages when testing available memory if the OS is configured to use Large Pages. Issue:DS-6760 SF#:1745
Update the replica code to never perform a search using the ds-sync-hist attribute on backends using the Berkeley DB database. Update error messages to better reflect severity and to omit reference to num-recent-changes on non-Berkeley DB backends. Issue:DS-6744
Update the JMX Connection Handler configuration to issue a warning if it is enabled. On some JVMs, enabling this aspect of JMX can lead to long garbage collection pauses. Issue:DS-6832
These features were added for version 3.2.0.0 of the Directory Server:
AIX is now a supported deployment operating system.
In the LDAP changelog, add support for indexing changes separately for each modified attribute, which allows clients to more efficiently retrieve changes to a subset of attributes using the get-changelog-batch request.
Update the LDAP changelog to provide support for paring down the contents of changelog entries based on the access control and sensitive attribute restrictions that are in place for the entry that was added, deleted, or updated.
Introduce an audit-data-security tool that identifies potential risks or other notable security characteristics contained in directory data.
Update the UnboundID work queue to add a dedicated thread pool that may be used for processing certain administrative operations. This dedicated thread pool may make it possible for an administrator to diagnose and take corrective action in a server even if all "normal" worker threads are tied up processing other operations.
These were known issues at the time of the release of version 3.2.0.0 of the Directory Server:
These issues were resolved with version 3.2.0.0 of the Directory Server:
Fix a bug in the web-console new Attribute Type and new Objectclass dialogs which is some cases could cause a schema element saved erroneously into a file called 'New File...'. Issue:3410
Modify the web-console so that extraneous carriage returns are removed from files containing exported schema elements. Issue:3411
Fix a bug that could cause inaccurate timestamps to be displayed in the active operations monitor entry for operations that are still waiting in the work queue and have not yet been picked up for processing by a worker thread. Issue:3419
Fix an issue that led to work queue backlogs in DS when the Sync Server was synchronizing from an entry-balanced Proxy Server configuration. Issue:3431 SF#:1486
The dsreplication tool's cleanup-local-server subcommand will now remove the public key certificates of all formerly trusted replicas as a result of being removed from a replication topology. Issue:3385
Update command-line tools providing support for SASL authentication to add additional properties that may be used in conjunction with the GSSAPI mechanism. This includes the ability to control whether a ticket cache should be allowed and/or required, the ability to specify an alternate location for the ticket cache file, the ability to request that the Kerberos ticket-granting ticket be renewed, and the ability to supply a custom JAAS configuration file rather than using one automatically generated by the tool. Issue:3437
Fix a bug that prevents going back from the type selection when creating a new configuration object in dsconfig. Issue:2913 SF#:1435
Update a number of LDAP command-line tools to provide a new --help-sasl option that can be used to obtain information about the SASL mechanisms that are available for use and the supported options for those mechanisms. In addition, the command-line tool reference has been updated to provide a new page on supported SASL mechanisms and options. Issue:3452
The replication server changelogDb directory can now be relocated because the replication-db-directory property is no longer read-only. Also, the LDAP Changelog Backend database directory can be relocated because it now has a db-directory property. Issue:3359 SF#:00001484
The dsreplication command line utility has been updated to prevent multiple dsreplication instances to be changing the replication configuration simultaneously.
The utility has been updated to keep a history of invocations in the logs/tools/dsreplication.history file.
The utility has been updated to keep the log of up to 10 dsreplication sessions in the logs/tools directory. Issues:2347,2716,623,661
Fix an issue where a subtree delete operation that timed-out could bring both replication and the LDAP changelog to a halt. Issue:3465
Fix a bug in which dsconfig and other tools may not properly evaluate path-based property values for remotely managed servers. Issue:3439 SF#:00001484
Fix an issue where the LDAP Changelog Backend could encounter a deadlock while purging old entries if changelog batch requests were simultaneously trying to read those entries. Issue:3080
Improve the consistency of performance for Sync through Proxy with Entry Balancing. When the Proxy Server is processing a Get Changelog Batch request and it has received maxChanges in total from the backend Directory Servers, it now cancels the outstanding requests in order to expedite the return of the result to the Sync Server. When the Directory Server receives a cancel request for a Get Changelog Batch request, it now stops processing the request and returns the result containing a resume token. Issue:3438 SF#:1492
Fix an issue in the Directory Server that could affect synchronizing changes through the Directory Proxy Server in an Entry Balanced environment that had global replication configured across all Directory Server instances. Under certain circumstances, the Directory Server would go too far back in the changelog when searching for the next batch of changes, and it might issue an incorrect warning that some changes had been purged. Issue:3543
Fix an issue in the Directory Server that could cause the Sync Server to show a large number of un-retrieved changes after restarting a sync pipe. This issue affected Sync through Proxy in an entry-balanced configuration. Issue:3543
Modify the update tool to handle potential issues migrating the admin-backend.ldif backend file if the ds-create-time attribute is present in the entry cn=all-servers,cn=Server Groups,cn=admin. Issue:3584 SF#:00001501
Update shell scripts used for the server and associated tools so that they will display a warning if it is not possible to set the desired number of file descriptors. Issue:3590
Fix a potential bug in index merge processing during import-ldif and rebuild-index processing that could cause the tool to silently complete without any indication of problems even if an error occurred. Issue:3590
Add je-property configuration to Changelog Backend to allow for advanced settings as needed. Issue:3600
Fix a bug when keeping track of an index that has exceeded the entry limit in the verify-index tool. Issue:3358
Fixed an issue in the LDAP Changelog where it could throw a NoSuchElementException either when it is first enabled or during replication replay. Issue:2760
Fix a bug where dsreplication cleanup-local-server command would fail in non-interactive mode if the changelogDir argument was not provided. Issue:3453
Update the JE backend to add new id2children-index-entry-limit and id2subtree-index-entry-limit configuration options that can be used to set the limits for these independently of the backend-wide default index entry limit. If these values are not set, then the backend-wide limit will continue to be used. Issue:3608
Change setup command to check for minimum required BDB JE version before running. Issue:3441
Update the CRYPT password storage scheme to make it possible to encode passwords using the 256-bit and 512-bit SHA-2 variants available in many Linux and UNIX distributions. These mechanisms apply multiple rounds of a very strong cryptographic digest to make the process of encoding passwords more expensive and significantly impede brute force, dictionary, and other kinds of attacks that may be launched by someone with access to a password's encoded representation. Issue:3593
Add support for a new "operation purpose" request control that clients can use to identify the intention for each request that they send to the server. The control may include the name and version of the application that created the request, the location in the application code from which the request was created (which may be automatically generated by the UnboundID LDAP SDK for Java), and a human-readable message explaining the purpose for the operation.
This can help improve security and debuggability because it can offer a kind of audit trail. If a request includes this control, then information from the control will be included in access log messages for those operations. Issue:3616
Add support for a number of operational attributes which can be added to user entries in order to restrict the way those users can authenticate and the circumstances under which they can be used for proxied authorization. Issue:3621
Fix an issue in the Directory Server that caused Sync Server polling to get stuck when changes had been purged from the changelog. Issue:3594
Increase the efficiency of LDAP changelog purging by reading less data from the database. Also, retry purge transactions that fail with a lock conflict exception. Issues:3595,3604 SF#:00001486
Update client connection policies to support two new configuration attributes. The required-operation-request-criteria property can be used to cause the server to reject any request which does not match the referenced request criteria, and the prohibited-operation-request-criteria property can be used to cause the server to reject any request which does match the referenced request criteria. Issue:3645
Add the ability to configure the LDAP Changelog backend to preload database files into the file system cache prior to purging changelog entries. This can eliminate high disk utilization during purging. Issue:3603 SF#:1486
Update the export-ldif tool to add a new "--encryptLDIF" option that can be used to cause the data to be encrypted as it is written. Also, update the import-ldif tool to add a new "--isEncrypted" option to make it possible to import LDIF data from an encrypted file. Both of these options are only available when running as a task with the server online, as is also the case when creating or restoring an encrypted backup. Issue:3617
Boost the performance of the Get Changelog Batch extended request in the Directory Server by using multiple threads to process the request. Issue:3606
Increase minimum heap size used by setup when no value is provided by end user. Issue:DS-3580
Fix a bug where a schema file shipped with the server was being listed as a custom schema. Issue:DS-3563
Update the LDIF export task to add support for digitally signing the contents of the LDIF export, and update the LDIF import task to add an option that can be used to verify the contents of the signature. If the import task is configured to verify signed content but the LDIF is not signed or has an invalid signature, then the import will complete but the server will place itself in lockdown mode to avoid the possibility of exposing untrusted data to clients. As with encrypted LDIF support, signing support is only available while the server is online and cannot be used in offline mode. Issue:DS-3617
Add a new argument to collect-support-data to control the number of jstack samples to collect. Issue:DS-4159
Update the FIFO entry cache to add support for new configuration options that make it possible to restrict the entry cache to holding only entries with at least a specified number of attribute values (either across all user attributes, or optionally across only a specified set of attributes). This can be used to avoid wasting cache memory with small entries that are very efficient to decode directly from the database and for which the entry cache does not provide significant benefit. Issue:DS-4210
Update the Directory Server to require a minimum Berkeley DB JE version of 4.1.10. Issue:DS-3549
Update dsconfig to make the list-properties subcommand more visible and more usable. This includes the following changes:
- The list-properties output will now be written to standard output rather than standard error. This makes it easier to process the output with text tools like grep.
- The list-properties subcommand can now be used with the "--offline" argument even if the server is running.
- A new "--complexity" argument has been added that can be used to customize the complexity level of the objects included in the output.
- A new "--includeDescription" argument has been added that can be used to include synopsis and description information in the output.
- The top-level dsconfig help now includes an example demonstrating the use of the list-properties option.
- A docs/config-properties.txt file containing this information is now provided with the server. This information was previously already available in the HTML config reference guide. Issue:DS-2985 SF#:00001413
Update a number of access loggers to provide a new max-string-length configuration property that specifies the maximum length of any string that may be included in a log message. If any string has more than this number of characters, then that string will be truncated and a placeholder will be apended to indicate the number of remaining characters in the original string. Issue:DS-3551
Update the server to provide a new additional-supported-control-oid configuration property in the root DSE backend that can be used to add a specified OID to the supportedControl attribute of the server's root DSE. This is primarily intended for compatibility with other servers which may include certain response control OIDs in this list even though LDAP specifications indicate that it should only include request control OIDs.
The Server SDK has also been updated to provide support for registering and deregistering supported control OIDs. This may be used for extensions which themselves add support for additional controls. Issue:DS-3467
Allow directory server to ignore illegal trailing space characters for existing schema files. Issue:DS-3586
Make it possible to configure the server to configure the number of file descriptors that it should attempt to use on UNIX-based systems. Previously, the server was hard-coded to try to use 65535 file descriptors. It is now possible to override this default by setting the NUM_FILE_DESCRIPTORS environment variable with the desired number of descriptors to use. Alternately, you can do this by creating a config/num-file-descriptors file with a single line, like:
NUM_FILE_DESCRIPTORS=12345
If an error occurs while attempting to use the desired number of file descriptors, then a message will be written to the terminal, and if the error occurs while starting the server, then a message will be logged to the server's error log. Issue:DS-3590
Fix a bug that prevented use of dsconfig with SASL options. Issue:DS-3535
Increase the concurrency of the FIFO Entry Cache when it contains a large number of entries. Issue:DS-4249
Add the ability to compress log files as they are written. This can significantly increase the amount of data that can be stored in a given amount of space so that log information can kept for a longer period of time. Because of the inherent problems with mixing compressed and uncompressed data, compression is something that can be enabled only at the time the logger is created, and compression cannot be turned on or off later. Further, because of problems in trying to append to an existing compressed file, if the server encounters an existing log file on startup, it will rotate that file and begin a new one rather than attempting to append to the previous file.
Compression is performed using the standard gzip algorithm, so compressed log files can be accessed using readly-available tools. Further, the summarize-access-log tool has been updated so that it can work directly on compressed log files rather than requiring them to be uncompressed first. However, because it can be useful to have a small amount of uncompressed log data available for troubleshooting purposes, administrators using compressed logging may wish to have a second logger defined that does not use compression and has rotation and retention policies that will minimize the amount of space consumed by those logs while still making them useful for diagnostic purposes without the need to uncompress files before examining them. Issue:DS-2983 SF#:00001410
Enable the isMemberOf virtual attribute by default so that it will be usable in an out-of-the-box deployment without any administrative action. Issue:DS-4267
Update the logic used for index evaluation so that it can skip evaluating some or all of the search filter against the entry if the parts which have been omitted are guaranteed to match the candidate entries based on the use of indexes. Issue:DS-4211
Add a new monitor entry for the FIFO Entry Cache that reports details on the operation of the cache. Also, update the Periodic Stats Logger to expose many of these statistics in a continuous fashion. Issues:DS-3657,DS-3658
Add a new option to the dsreplication tool that can be used to override a lock on the topology held by a separate invocation of the tool. This option should be used with caution. Issue:DS-3487
Update dsconfig to remove a redundant prompt when a user chose to "Change the value" of an existing property. Issue:DS-2140
Fix a bug that prevented collect-support-data from properly using SASL connection options Issue:DS-4239
Include a "Static Group Entry Cache" in the out-of-the-box configuration to improve server performance with large static groups whenever this entry cache is enabled. Issue:DS-4248
Fix an issue where, in rare circumstances, replication did not forward some update messages. Issue:DS-4329
Add a change to prevent server from being considered degraded when creating a new index. Issue:DS-4217
Address rare case when the dsreplication utility assigned the same identifier to a replication server and a replication domain causing a failure during online initialization. Issue:DS-3472
Fix a bug that could cause a search result to incorrectly indicate that zero entries were returned to the client. This only occurred when using a Server SDK plugin to return additional search entries to the client during processing. Issue:DS-4349
Improve search performance when an ACI references a group that does not exist. Issue:DS-4365
Modify updater tool to ignore conflicting configuration additions that already exist. Issue:DS-4352
Update the simple search entry criteria configuration object to indicate that the included-entry-filter options will be evaluated against the pared-down entry actually returned to the client rather than the complete entry that exists in the server. Issue:DS-4360
Improve the write throughput of the LDAP changelog when persistent searches are active in the directory, but none apply to the changelog content. Issue:DS-4494
Fix a bug where some configuration variables were not initialized during LDIF import on a changelog backend. Issue:DS-4419
Update the replication server monitor entry to include an ssl-encryption-available attribute that indicates whether the server supports replication over SSL.
Note that even if the server is configured to support replication over SSL, it does not mean that all communication actually uses SSL. The ssl-encryption attribute of the replication server handler monitor entries should be examined to determine where SSL is and is not in use for replication. Issue:DS-3238
Prevent improper state propagation in replication that used to result in increased protocol traffic. Issue:DS-4493
Add a new reject-insecure-requests global configuration option that can cause the server to reject all operations except StartTLS extended requests received over insecure connections. This makes it easier to allow clients to use StartTLS without allowing other requests over an insecure connection. Issue:DS-4397
Provide an alternate password policy in the out-of-the-box configuration that is significantly more secure than the default policy. This policy is not configured for use, but it can be selected as the default policy, used as a policy for a select set of users, or used as a template creating a new custom policy with a more secure starting point than the default policy.
In addition, a new sensitive attribute definition is included in the default configuration that declares userPassword and authPassword to be sensitive attributes and forbids them from being returned to clients, used in search filters, or targeted by compare operations, and also requires that adds and modifies including passwords be processed over a secure connection. This sensitive attribute definition is not used by anything by default, but it can be easily referenced in the sensitive-attribute option of a client connection policy to turn it on. Issue:DS-4396
A server restart is no longer required after setting up replication to use encrypted communication. Issue:DS-1459
Update server access loggers to add a number of new options:
- An option to include request details in search result entry messages. - An option to include request details in search result reference messages. - An option to include request details in intermediate response messages. - An option to include the names of attributes included in an add request. - An option to include the names of attributes targetd in a modify request. - An option to include the names of attributes included in a search result entry. - An option to include extended search request details, including the size limit, time limit, types only, and alias dereferencing behavior. Issue:DS-4404
Update the server to add a "--lockdownMode" argument which can be used to cause the server to be started in lockdown mode. Issue:DS-1488
Update the Directory Server to make it possible to define sensitive attributes as a global configuration option that will automatically apply across all client connection policies. It was previously only possible to associated sensitive attributes with individual client connection policies, and this option still exists. In addition, it is possible to indicate that a client connection policy should exclude one or more global sensitive attributes. Issue:DS-4402
Update the server to generate an administrative alert if it detects that a configuration change was made with the server offline (whether by manually editing the configuration file or using dsconfig in offline mode). Issue:DS-4407
Improve the 'excludeReplication' option on the export-ldif command to also exclude replication conflict entries in addition to replication related attributes. Issue:DS-3332
Update the server to provide better reporting around the use of third-party extensions. If any such extensions are loaded in the server, then the DNs of their configuration entries will be listed in the thirdPartyExtensionDN attribute of the cn=monitor entry. Further, some extensions are loaded at startup, and a message will be written to the error log with the DNs of all of their configuration entries. Please note that not all extensions are loaded at startup, in particular Sync extensions. Issue:DS-4398
Improve the performance of searches that do not return any results by not fetching the base entry of the search unless it contains referrals. Issue:DS-4525
Fix an issue in which terminal focus may be lost during command-line setup just before the Summary step is shown. Issue:DS-4551
Fix an issue in which dsconfig cannot set an unlimited value for an object property that supports an unlimited value. Issue:DS-4173
Update the UnboundID work queue to add a dedicated thread pool that may be used for processing certain administrative operations. This dedicated thread pool may make it possible for an administrator to diagnose and take corrective action in a server even if all "normal" worker threads are tied up processing other operations. By default, eight worker threads will be created for this purpose, but this may be altered via the num-administrative-session-worker-threads property in the work queue configuration.
Some administrative tools like dsconfig, status, collect-support-data, enter-lockdown-mode, and leave-lockdown-mode will automatically attempt to create an administrative session in which all operations they request will be processed in this dedicated pool. Other tools like ldapsearch, ldapmodify, ldapcompare, ldapdelete, ldappasswordmodify, backup, restore, import-ldif, export-ldif, and manage-tasks have a new "--useAdministrativeSession" argument that can be used to request that they attempt to use this dedicated thread pool for operations that they process. Further, the Commercial Edition of the UnboundID LDAP SDK for Java has been updated to provide support for the new start administrative session and end administrative session extended operations that are needed to use this feature, so third-party applications can also take advantage of this capability.
In order to request that operations be processed using the administrative session thread pool, the requester must have the use-admin-session privilege (which is included in the default set of privileges automatically granted to root users). The use of the administrative session thread pool will be recorded in the access log, and a new "using-administrative-session-worker-thread" property has been added to the simple request criteria and can be used to filter operations based on whether they are using this capability. Issue:DS-4401
Fix SASL support for the status command. Issue:DS-4313 SF#:1563
Update the changelog backend to provide support for paring down the contents of changelog entries based on the access control and sensitive attribute restrictions that are in place for the entry that was added, deleted, or updated. This capability is disabled by default, but it can be enabled using the apply-access-controls-to-changelog-entry-contents configuration property. If enabled, then the contents of attributes like changes, deletedEntryAttrs, ds-changelog-entry-key-attr-values, ds-changelog-before-values, and ds-changelog-after-values may be altered or removed based on what the requester can access in the target entry.
This change also includes support for a new option in the get changelog batch extended request. If the pareEntriesForUserDN element is present in the request, then the changelog entry contents may be further pared down to match the intersection between what is accessible to the requester and the user specified in that pareEntriesForUserDN element. If this element is included in the get changelog batch request, then this paring will be performed even if apply-access-controls-to-changelog-entry-contents has a value of false.
If the changelog entry content was altered as a result of this processing, then the changelog entry returned to the client may include additional information about what was removed. If the report-excluded-changelog-attributes configuration property is given a value of attribute-counts, then information about the number of suppressed user and operational attributes will be provided in the changelog entry through ds-changelog-num-excluded-user-attributes and ds-changelog-num-excluded-operational attributes. If it is given a value of attribute-names, then the names of the suppressed attributes will be provided in ds-changelog-excluded-user-attribute and ds-changelog-excluded-operational-attribute. Issue:DS-4157 SF#:00001409
Dramatically reduce the memory consumption of static groups, especially when the ratio of total memberships to unique members is high. The configuration property cache-user-to-group-mappings should only be disabled if nested group support is needed as it helps to reduce memory consumption. The property intern-member-dns is removed since it is no longer useful. Issue:DS-4698
Update the replication server to fix two potential race conditions that result in an error message "Replication server caught exception while listening for client connections null" . Issue:DS-4557
Fix a bug where collect-support-data was not passing all of the SASL arguments needed to the status command. Issue:DS-4816
Remove bind user and password prompts when starting dsconfig in interactive mode if valid SASL bind options are provided. Issue:DS-4579 SF#:1562
Change collect-support-data to not prompt for bind user/password when SASL arguments are provided. Issue:DS-4596
Fix a bug that could cause virtual and real values for the same attribute type to be returned as two separate attributes, which could cause problems with some kinds of LDAP clients. Issue:DS-4707
Update the Directory Server support for virtual attributes so that it is possible for multiple virtual attribute definitions to contribute values to the same attribute in an entry. Previously, only one virtual attribute definition would be used, and the process for selecting that one definition was not well defined.
As part of this solution, two new configuration properties have been added to virtual attribute definitions:
* multiple-virtual-attribute-evaluation-order-index -- This is a numeric value which can be used to assign relative priorities to virtual attribute definitions. Definitions will be evaluated in ascending order based on this index, and definitions without an explicitly-assigned index will be evaluated last. It is acceptable to have definitions with the same index, in which case their relative order will be determined based on lexicographic comparison of the name of the configuration object. It is also acceptable to have gaps in the ordering, so it is not necessary to define the order using only sequentially-increasing values.
* multiple-virtual-attribute-merge-behavior -- This specifies the behavior that the server should use when multiple virtual attribute definitions apply to the same multivalued attribute in a given entry (for single-valued attributes, the server will only ever use the first definition as determined by the order specified above). Values for this property may be "use-first-definition" (in which case only the first applicable virtual attribute definition may contribute values to an entry), "use-only-definitions-with-the-lowest-evaluation-order-index" (in which case the first applicable definition will be used, along with all other definitions that have the same evaluation order index as that first definition), or "use-all-definitions" (in which all applicable virtual attribute definitions may contribute values to the entry).
In the event that multiple virtual attribute definitions will be applied for a given attribute in an entry, the conflict-behavior and multiple-virtual-attribute-merge-behavior values for the first applicable definition will be used for all virtual attribute definitions applied for that attribute, even if subsequent definitions have behaviors that conflict with that of the first applicable definition. Issue:DS-2483
Update the logic the server uses for address patterns to support the use of subnet masks. It was previously only possible to use CIDR notation (e.g., "1.2.3.0/24") to specify the number of significant bits, but it is now possible to use subnet masks (e.g., "1.2.3.0/255.255.255.0") to specify address masks. Issue:DS-4710
Improve the server to now report group cache stats and memory usage at startup. Issue:DS-2855
Modify the tools to recognize instances of the Sun DSEE 7 Directory Server when deployed as part of the Oracle Identity Management 11g. Issue:DS-4716
Update the server to discourage disabling schema checking since this can lead to unexpected behavior in the server and client applications, as well as introduce performance problems. A warning message is printed when dsconfig or the console is used to update the configuration to disable schema checking. The server now generates an alert when schema checking is disbled. The --skipSchemaValidation option has been removed from import-ldif. Issue:DS-4336
Improve the config definition for the idle-lockout-interval password policy property to indicate that it relies on the last login time but may fall back on the password changed time or account creation time if no last login time is available. It also recommends having last login time tracking enabled for a period of time before enabling idle account lockout. Issue:DS-4878
Update the server to record access log information about certain requests rejected very early in the life of an operation that were not previously recorded, including:
- Operations requested by a user that must change his/her password before being allowed to perform any other operation. - Operations rejected because there is a bind in progress on the connection. - Operations rejected because the server is in lockdown mode. - Operations rejected as a result of the reject-unauthenticated-requests or reject-insecure-requests configuration option. - Operations rejected because a client has exceeded the maximum number of operations per connection or maximum concurrent operations per connection. Issue:DS-4912
Make a change to the entry encoding format for attributes with attribute options. This will primarily impact data sets which use a wide variety of attibute options (and especially those other than ";binary" or ";lang-*"). In data sets with a very wide variety of attribute options, LDIF import and LDAP add performance should be dramatically improved.
Note that this may have an impact on the ability to revert to an older version if the data makes use of attribute options other than ";binary" or ";lang-*". In such cases, or in cases in which the data may use attribute types not defined in the server schema, then you should export data to LDIF before performing the revert, and then re-import data from LDIF after the revert. Issue:DS-4869
Fix a bug in the attribute value password validator that can cause it to incorrectly reject add attempts if the password attribute itself is included in the set of attributes to examine. Issue:DS-4888
Update the changelog backend to add a new include-virtual-attributes property that can be used to indicate when virtual attributes can be included in changelog entries. Virtual attributes may be included in none, some, or all of the following cases:
- The set of attributes for an add operation - The set of deleted entry attributes for a delete operation - The set of changes for a modify operation (but only when use-reversible-form is true -- when it's false, the changes are what the client sent the server) - The before and after values for updated attributes (regardless of the value of use-reversible-form) - The key entry attributes Issue:DS-4714
Update the behavior of 'use-reversible-form' on the Changelog Backend to make sure it always includes a changelog entry, even if there was no net change to the directory entry. Changing attributes to the same value they already had will now result in an ADD and a DELETE of those same values showing up in the 'changes' attribute on a changelog entry, to provide an indication of what was in the original modification. Issue:DS-4957
Add support for the IBM JDK for the GSSAPI SASL bind mechanism handler and when using GSSAPI SASL binds with tools and utilities. Due to restrictions with the IBM JDK, when using tools and utilities and the option "ticketcache" is set, the bind will always fail if the credentials are not found in the specified ticket cache, even if the option "requirecache" option is false. Issue:DS-4749
Change the default low-space-error-percent-threshold to 1. This will help to avoid costly database recovery and/or replication initialization operations when the directory server runs out of disk space on default installations. Issue:DS-4872
Address an issue with the LDAP Changelog where a modify operation that added and deleted the same value for an attribute (effectively a no-op) would show up in the changelog incorrectly. Issue:DS-5005
The LDAP change log now supports attribute indexing so that the Sync Server can request changes that target specific attributes much faster. This feature is configured by the index-include-attribute and index-exclude-attribute properties on the Changelog Backend. Issue:DS-4938
Update the LDAP Changelog Backend to separate out virtual attributes from real attributes. There are now separate attributes for storing before/after values, key attributes, and added or deleted entry attributes which are virtual. Virtual attributes are not included in changelog entries at all by default, but can be included in any or all of before/after values, key entry attrs, added entry attributes, and deleted entry attributes using the 'include-virtual-attributes' property on the changelog backend. Issue:DS-5043
Fix a bug in which the server did not always properly handle changes to an attribute with the same attribute type as used in an entry's RDN and could reject an operation with a "not allowed on RDN" result when the RDN value itself was not actually altered. Issue:DS-4950
Improve the dsframework tool to support multi-valued server propreties. Issue:DS-5040
Critical: Fix a bug where Directory Servers could potentially miss some update messages in large topologies after a restart. Issue:DS-3592
Update the Local DB Backend so that the way that individual indexes (including system indexes) are preloaded aligns with the index's cache-mode setting. If a cache-mode is set to evict-leaf-immediately, then leaf nodes will never be preloaded. If a cache-mode is set to evict-bin-immediately, then nothing will be preloaded. Issue:DS-4860
Hide the include-backend-subtree-views property in client connection policy configuration objects in the Directory Server. The only legitimate use of this configuration property is in the Directory Proxy Server, so it should not be exposed in the Directory Server. Issue:DS-5057
Change collect-support-data and a couple of other tools to enable use of a tools.properties file when present. Issue:DS-4932 SF#:1563
Fix a bug that prevented configuration changes to attribute syntaxes (e.g., to allow zero-length directory string values) from taking effect without a server restart. Issue:DS-5060
Fix a bug to prevent server registry from corruption where, in some cases, the dsreplication detach subcommand used to update the server registry of the detached servers before the replication servers disconnected from each other. Issue:DS-5058
Fix a bug that required server restart when re-enabling virtual attributes. Issue:DS-5106
Fix an issue with replication where a server might miss some changes, specifically during stress tests that included a high volume of modify traffic and repeatedly killing the server process. Issue:DS-5227
Fix a bug that prevented use of stop-ds command on a remote server. Issue:DS-5279
These issues were resolved with version 3.1.0.0 of the Directory Server:
The dsreplication tool now requires specification of the --ignoreWarnings option when performing a pre-external-initialization operation using the --no-prompt option. Issue:3019
The dsreplication status output has been updated to include a table that lists replication servers and their important properties. Issue:3019
The dsreplication tool now disallows specification of an empty password for the global admin user account. Issue:3019
The dsreplication tool now prohibits enabling replication between two servers for base DNs of empty subtrees. Before enabling replication, at least one servers must have been initialized with data. Issue:3019
The dsreplication tool's interactive menu system has been overhauled to provide better organization and contextual help for its operations. Issue:3019
Add new global configuration attribute that allows specifying a SMTP timeout to use for all configured SMTP servers. Issue:2283
Change dsreplication command line interface to detect an invalid hostname provided during an interactive session, instead of failing at the end. Issue:2763
Update the server so that access log messages for operations the server tried to interrupt (e.g., as the result of an abandon or cancel request, because the client connection was being closed, because the server was shutting down, etc.) will include an additionalInfo element with more information about the reason for the cancel attempt. Issue:2971
Limit collect-support-data to only run against the local server it is ran from. All supported versions of the products have collect-support-data available, and should use that version to do any needed data collection. Issue:2827
Enhance timeout for SMTP External Servers to be used for socket I/O and connection based timeouts. Previously the timeout value applied only to socket I/O. Issue:2939
Fix an issue with export-ldif command that resulted in object classes always being included in the output. Issue:2482
Heartbeat messages on replication server connections used to be ignored. Issue:3016
The update and revert-update tools now respect that -Q/--quiet option which when specified, suppresses console output of messages that are not warnings or errors. In addition, the tools will not solicit input if the -n/--no-prompt option is specified. Issue:3056 SF#:00001432
Add an option for configuration group change failures to force configuration changes when one or more servers in the group are unable to process the operation. Forcing the change is optional and the user is given a chance to modify the configuration change and retry if they decline. The --applyChangeTo argument now allows a value of "server-group-force" to provide the same functionality non-interactively. Issue:789
Fix an issue where the Web Console provides a dsconfig command to modify root dn user aliases that does not work in dsconfig. Dsconfig will now accept those commands. Issue:1692 SF#:1238
Improves our port checking code for local ports to be more accurate. Issue:2621 SF#:1399
The dsconfig tool has been fixed to that it does not exit in an error when the root DSE entry is not available. Issue:3122
Add a new type of access logger which can be used to obtain very detailed information about requests and responses and the contexts in which the associated operations have been processed. This is primarily intended for troubleshooting purposes rather than general use, and the content is meant to be human-readable rather than machine-parsable. Further, because the output can be quite verbose, it is recommended that it only be enabled when attempting to diagnose a problem, and that it be used in conjunction with the filtered logging framework so that only potential messages of interest will be captured. Issue:3064
Update tools, such as searchrate, that use --ratePerSecond to not use 100% of one CPU when running at a low rate. The cutoff for this rate depends on the minimum amount of time that a process can sleep, which is operating system dependent.
Enable the UseLargePages JVM flag during setup for Linux systems when the aggressive tuning option is used. Issue:2804
Update the Server SDK to add support for creating file-based access and error loggers. The new APIs are similar to the existing access and error logger APIs, but they take advantage of the server's existing high-performance and high scale log writer and provide support for advanced features like log file rotation and retention policies. Issue:3115
Add the ability to cancel an index rebuild task in the server. Previously, this was not possible and it could prevent an administrator from aborting an index rebuild, or even prevent the server from shutting down if a rebuild was in progress. Note that if an index rebuild is interrupted, then the index will remain untrusted and the rebuild must be re-invoked in order to allow that index to be properly generated before it will be used again. Issue:2955
The replication code has been updated to avoid a race condition when updates may not be delivered to a replica that was just added to the topology for a short period of time. Issues:2222,3159
Fix an issue where a disabled backend in the directory server could cause sync server endpoints to become out of sync when synchronizing through the proxy server. By default, a disabled backend now causes the directory server to set a degraded alert and to reject operations in the backend with the UNAVAILABLE result code. This allows the proxy server to route around the degraded directory server. Two new configuration properties on the backend control this behavior: set-degraded-alert-when-disabled and return-unavailable-when-disabled. Issue:3143
Update the way that the rebuild-index tool works in offline mode so that it can use multiple threads to provide better performance and scalability, and to reduce the amount of disk space consumed during the rebuild process. Also, update the way that the verify-index tool works when examining entries so that it can provide better performance and scalability, particularly when used to validate multiple indexes at the same time.
Update the rebuild-index tool so that it will monitor available disk space on volumes containing the database files and the temporary index files. If disk space gets too while rebuild-index processing is in progress, then it will log warning messages and may abort processing if available disk space becomes critically low. Issue:3251
Add the close-connections-on-explicit-gc option to the LDAP Connection Handler to allow connections to be closed gracefully when an explicit garbage collection is triggered by the Periodic GC Plugin or the Force GC Task. This allows hardware load balancers to more easily fail over to other instances. Outstanding operations will be given a chance to complete before connections are closed. Issue:2931
Update the Directory Server's support for interactive transactions so that it properly honors the writeLock flag in the interactive transaction specification request control. Issue:3263
Add a validate-acis tool that can be used to read access control definitions from an LDIF file or an LDAP directory in order to determine whether they will be accepted in an UnboundID Directory Server. Issue:3062
Update the move-entry tool so that it provides the ability to move multiple entries rather than just one. The --entryDN argument can be provided multiple times to specify the target entry DNs, or the new --entryDNFile argument may be used to specify the path to a file containing the DNs of the entries to move. If multiple entries are to be moved, then a separate transaction will be used for each. Issue:3111
An issue in the public key management process could cause replication to fail with certificate errors. Issue:3268
Fix an issue where a failed rebuild-index task did not release the lock it had acquired on the backend. Issue:3282
Make the download instructions for BDB JE more accurate. Issue:2980
Update collect-support-data to collect more system level information (especially on Linux) and validate that any value specified with the --pid option does not match the servers PID, since information about the server process is always collected. Issues:2920,2930,3152,3171,3206
The replication code has been updated to fix a rare race condition found when reinitializing a very small database immediately after starting the Directory Server. Issue:3302
Hide the subtree-view option in the Client Connection Policy configuration in DS and Sync. There is currently no way to create manual subtree views for these products, but this option may be add back for future features as needed. Issue:3125
Fix an issue where a valid ACI was rejected because the ACI name included a parenthesis. Issue:3145
Update the LDIF parser to reject entries with illegal trailing spaces with a better error message that more clearly explains what the problem is. Also, update the import-ldif and ldapmodify tools so that they provide a "--stripTrailingSpaces" option that can cause the LDIF parser to strip off illegal trailing spaces rather than rejecting the associated entry or change record. Issue:3216
Two new Local DB Backend configuration properties are available to control the behavior of the directory server when the contents of one or more Local DB Indexes are untrusted. An index is untrusted if it needs to be rebuilt, or is in the process of being rebuilt. The first property, 'set-degraded-alert-for-untrusted-index', determines whether the directory server enters a degraded state when the backend has an index whose contents are untrusted. The second property, 'return-unavailable-for-untrusted-index', determines whether the directory server returns UNAVAILABLE for any LDAP search operation that would use an untrusted index of the backend. The default settings are 'true', which allows a proxy server to fail over to an alternate directory server when the contents of one or more Local DB Indexes are untrusted. Issue:3143
Add a --missingOnly option to ldap-diff to allow the tool to only report on entries that exist on only one of the servers; entries that exist on both servers but are out-of-sync are ignored. Issue:2918
Update tools which can be used to schedule tasks to add a new "--task" argument that makes it explicit that the tool is intended to run as a task rather than in offline mode. At present, this argument is optional, but we intend to make it required in the future, and if a tool is invoked as a task without this new "--task" argument, then a warning message will be displayed recommending that it be used in the future.
In addition, if the "--task" argument is provided but the tool was not given an appropriate set of other arguments to allow it to connect and/or authenticate to the server, then an error message will be displayed and the tool will exit with an error. This behavior will also be exhibited for other arguments that are only applicable for tools running as tasks, including the "--start", "--dependency", "--failedDependencyAction", "--completionNotify", and "--errorNotify" arguments. Issue:3224
Update the manage-tasks tool so that it can detect cases in which the authenticated user doesn't have permission to access information about tasks in the server and will provide a more useful error message. It would previously always report that there were no tasks in the server, which may not be true and is not very helpful. Issue:2957
Change the default access logger configuration so that intermediate response messages will be suppressed rather than logged, although logging them can be enabled if desired. However, for operations that did send one or more intermediate response messages to the client, the result access log message will now include an intermediateResponsesReturned element that provides the number of intermediate response messages that were returned. Issue:3096
Fix an issue in online rebuild-index processing that can cause incorrect counts for the total number of entries and the number of entries processed so far. Issue:3283
Update tools which create scheduled tasks to display a message indicating that killing the tool will not interrupt the task. For tasks that can be interrupted, the tool will also display a manage-tasks command line that can be used to cancel that task. Issue:2954
Fix an issue in the subtree delete implementation that could cause subordinate entries to be deleted without removing the parent, and a failure result for the operation in the case that the number of subordinate entries exactly matched the subtree delete size limit. Also, slightly modify the interpretation of the subtree delete size limit to be the maximum number of subordinate entries that can be removed so that the base entry itself is not counted as part of this limit. Issue:3335
Updated the Directory Server so that the backlog of replication changes is received from only one other server in case the instance was disconnected from the topology for a long period of time. Issues:1105,2886
Added support for the special values "*" and "+" to the LDAP changelog configuration so that all user attributes or all operational attributes can be included or excluded from changelog entries. Issue:3269
Update the LDAP changelog so that it will not create a changelog entry with an empty 'changes' attribute when all modifications within a replicated modify operation are discarded because they are stale with respect to the local entry. Issue:3349
Fix an issue in the migrate-sun-ds-config tool that could cause it to generate a configuration batch file that could not be successfully applied when it included the creation of a new backend. Issue:3129
These issues were resolved with version 3.0.3.0 of the Directory Server:
Upgrade the server to require Berkeley DB Java Edition 4.1.8, which fixes a potential deadlock issue found in version 4.1.7.
Add support to the LDAP changelog for capturing all the before/after values of a changed attribute. This can be capped at a maximum number of values to store per attribute. Also add support to the LDAP changelog for capturing the current value of any 'key' attributes on every change to an entry, regardless of whether they were the attributes that changed. Issues:3020,3060
Fix a bug in web consoles where version mismatch warning was not being displayed on initial login. Issue:3146 SF#:1459
Add an option to collect-support-data for collecting data from expensive processes. These expensive operations will not be executed by default. Issue:3176
Clarify the results of the status command when a user attempts to collect status from a remote server. Status results will always be based on the local server even if the user attempts to run the command on a remote server. Issue:3121
Fix an issue where debug messages logged by a command line tool (when using --enableDebug) might not be flushed to disk before the command exited. Issue:3218
Update the server's support for GSSAPI authentication to allow it to use a more flexible service principal. Previously, the service principal was hard-coded to be "ldap/" followed by the fully-qualified name of the system. This is still the default, but it is possible to override that in order to use a custom service principal. In addition, client tools which support GSSAPI authentication have been updated to support a "protocol" SASL option that can be used to specify the protocol for the service principal, and a "debug" SASL option that can enable GSSAPI debugging in the JVM. Issue:3262
Change replication server logic to prevent resending updates to pre-3.0 replication servers whenever they leave the replication topology, as this could temporarily lead to larger than expected backlogs. Issue:2911
These issues were resolved with version 3.0.2.0 of the Directory Server:
Modify the update tool to fix an issue where in some cases the tool would fail to migrate an older configuration, displaying errors related to duplicate LDIF change records. Issues:2942,2962,2967
The status-panel tool is no longer supported and has been removed from the server packaging. Issue:2973
Fix an issue where a Mirror Virtual Attribute Provider could cause a stack overflow in the directory server. Issue:2999
Fix in issue in the Directory Server that could cause a search result entry to be artificially delayed (and possibly returned after its subordinates) if a search spans multiple backends and is indexed in some of those backends but is unindexed in others. Issue:3008
Fix a regression with the stop-ds command where the port argument was ignored. Issue:2925
Fix a replication incompatibility issue between a version 2.1.2 server instance and a server instance updated to a later version. The updated server could not process replicated modify operations from the older version instance. Issue:2935
Fix an issue, where in rare cases, the flow control mechanism in the replication server delayed message. Issue:3027
If replication is enabled, the access logger now reports the replication change ID in the access log by default. Issue:3030
The command 'dsreplication cleanup-local-server' now removes all administrative information from the local server including any known servers and configured server groups. Any prior steps made to register the server with a replication topology or a configuration server group will need to be repeated if necessary. Issues:2792,2868
Fix an issue where the status command would warn that the port argument was ignored even though the argument was not provided. Issue:3052 SF#:1447
The command-line tools now use the full terminal width for output on Windows platforms. Issue:1019
Fix a potential issue that could cause an exception if a client tried to establish a secure connection to a server that already had the maximum number of concurrent client connections established for the associated client connection policy. Issue:3072
Add a document which describes differences in the default behavior between the UnboundID/Alcatel-Lucent 8861 Directory Server and Sun/Oracle DSEE and the reasons for those differences. With minor editing, this document may also be used as a dsconfig batch file to apply changes to the Directory Server to make it behave more like DSEE. Issue:2978
The 'dsreplication disable' command now removes the ds-sync-state attribute from the formerly replicated backend. Issue:2887
Fix an issue where a disable and enable of a local DB Backend could result in lost replication changes. Issue:3001
Fix a potential problem that could cause replication to break when merging two previously-disconnected topologies with multiple servers, or when concurrently adding multiple new servers to an existing replication topology. Issue:3114
Increase the default value for duplicate error messages (allow 2000 in 5 minutes) and alerts (allow 100 in 1 hour) before they are suppressed. Avoid duplicate suppression for certain types of alerts, such as configuration changes. Ensure that the severity of a duplicate alert summary message matches the severity of the duplicate messages being suppressed.
Fix an issue that could cause search result entries returned by a persistent search to be significantly delayed. Issue:3128
Address an issue where Server SDK extensions running within a command line tool could cause the process to run out of memory if they logged a high volume of error log messages. Issue:3173
These issues were resolved with version 3.0.1.0 of the Directory Server:
Change collect-support-data tool to prompt for missing LDAP connection arguments if needed. Issue:2461
Fix an issue where an incorrect search base DN would be written in the access log when a search operation spanned multiple backends.
Add support for a new exclude branch request control, which may be used to suppress search result entries below one or more base DNs. Issue:2845
Update the Directory Server so that when processing a search operation, it will try to consolidate the last search result entry with the search result done message so that we try to send both messages in the same packet. This improves search performance and reduces network congestion. Issue:2853
Update sensitive attribute support to utilize the intermediate client request control if present in the client request in order to determine whether all downstream clients communicated with the server over a secure connection, rather than just considering the communication with the immediate client. This can help make more intelligent determinations for operations requested through a Directory Proxy Server instance. Issue:2852
Update the server so that some of the specialized access loggers (e.g., failed operations and expensive operations) do not include messages about intermediate responses. Issue:2822
Update the attribute value password validator to provide the ability to perform substring matching on passwords. With this capability enabled, it is possible to reject passwords which are substrings of attribute values, or to reject passwords which contain substrings of attribute values. Issue:2579
The replication changelog backend (replicationChanges) is now always enabled to facilitate restoring the replication changelog database from another server before replication is enabled. Issue:2645
Fix a bug that could prevent the use of object classes which reference attribute types whose name begins with a numeric digit or contains an underscore character. Although such names are technically invalid, the server may allow based on the value of the allow-attribute-name-exceptions global configuration property. Issue:2882
Fix a bug that could cause some command-line tools (including ldapsearch and ldapmodify) to fail when parsing DNs containing attributes whose names require the attribute-name-exceptions feature in the server, even if that feature was enabled. Issue:2883
Fix a bug in the import-ldif tool that caused it to ignore the server's check-schema global configuration property and always perform schema checking unless the --skipSchemaValidation argument was provided. Issue:2891
Fix a regression that was causing replication initialization to fail if the domain name included a dot character. Issue:2894
Address an issue with collect-support-data when run on Windows where certain commands that were executed would timeout without reading the full output of the command.
Replication now issues an alert if the replica is unable to publish all updates messages to the replication server before shutting down. Issue:2720
Upgrade the server to require Berkeley DB Java Edition 4.1.7, which fixes a couple of notable bugs found in version 4.1.6.
Add a new external server type for configuring SMTP servers. This can be used to provide secure connections and authentication to outgoing mail servers. Issue:1150
Fix a bug in which one or more backend indexes could be incorrectly considered trusted if LDIF import or index rebuild processing was interrupted before completing index-related processing. Issue:1944
The SNMP Master Agent Plugin is no longer exposed as configurable because it is not a supported component. It is only used for test purposes.
During shutdown, suppress replication error log messages that are triggered by closing connections to remote replication servers. Issue:2349
Fix a bug in the web console that prevented the creation of configuration objects with a slash character in the name. Issue:2836
Add the ability to log debug statements from server components that are running within the context of a command line tool. This also enables logging from third-party extensions developed with the Server SDK to be captured when run from the context of a command line tool. Issue:2834
The dsframework tool has been modified so that whenever a server is registered or updated with port values whose corresponding protocol enablement properties (ldapEnabled, ldapsEnabled) are not present, the tool will automatically set the value of the enablement property to "true". Issue:783
The dsreplication enable subcommand in interactive mode used to fail when one of the Directory Server instances had the global administrator user defined. Issue:2843
Update replication messages and monitor attributes to use the term "Replication Backlog" instead of "Missing Changes" since "Missed Changes" refers to changes that have been lost due to purging. Issue:2736
dsreplication detach subcommand now requires that all servers in the topology to run version 3.0 or later. Issue:2844
These features were added for version 3.0.0.0 of the Directory Server:
Database Cache Compaction - With many datasets the database cache now uses 10-20% less memory to cache the same data.
Server SDK - Server-side SDK for extending the functionality of the core server.
Entry Encryption - Full entry-level encryption for Local DB backends.
Sensitive Attributes - An additional layer of protection from exposing data that is considered sensitive by allowing you to define policy that restricts how clients interact with a set of attribute types. For instance, you can define policy that will perform some of the following actions: 1) Reject add, compare, modify, or search requests that target these attributes, 2) Force clients to connect with a secure connection to interact with them, or 3) Automatically strip them out of entries before returning them to clients.
Virtualization Support - Achieved "VMware Ready Status" for all of our server products, which we now support deploying in VMware environments.
Global Replication - Support for replicating shared data between data sets in an Entry Balanced environment. This includes centrally managing and monitoring replication for all Directory Servers in an Entry Balanced environment.
These were known issues at the time of the release of version 3.0.0.0 of the Directory Server:
These issues were resolved with version 3.0.0.0 of the Directory Server:
Fix a bug that could cause a recursion loop resulting in a stack overflow when using aggregate connection criteria. Issue:2240
Expose version information for many of the libraries used by the server in both "status --fullVersion" and in the "cn=Version,cn=monitor" entry. It will always include the LDAP SDK version number, and if available may also include any or all of the Berkeley DB JE, JZlib, SNMP4J, SNMP4J Agent, and SNMP4J AgentX library versions strings.
Add a configuration option that may be used to indicate whether the server should shut down in the event that a severe error (e.g., out of memory) is raised within the JVM that indicates it may not be able to continue running properly. Issue:2265
The dsjavaproperties tool now supports options for generating, regenerating, and updating the config/java.properties file. Issue:2280
Fix a bug in the support for the simple paged results control that could cause it to fail for a search that was unindexed. Issue:2286
Fix a bug in the timestamp-naming mechanism used in log file rotation which could cause log files that were manually renamed to still get rotated and eventually deleted if their names were still parsable as the original file name. Issue:1285
Fix a bug in the implementation of the userattr access control bind rule that could cause an access control rule to fail to properly match entries. Issue:2310
Fix a bug in the server that may cause the server to incorrectly parse some extensible match search filters from their string representations. Issue:2313
Update the stop script so that the "restart" option will correctly restart the server after a successful shutdown Issue:2329 SF#:1362
Address an issue where the dsreplication command line utility in interactive mode ignored the selection from a server list and used the currently connected server to execute subcommands. This issue affected the disable, initialize, and initialize-all subcommands. Issue:2335
Issue an new admin alert when a replication operation fails to be replayed due to abnormal circumstances. Issue:2353 SF#:1368
Update dsconfig to work correctly in environments with a server-group set. This issue only affected dsconfig when run in a partially interactive mode where some of the configuration arguments were provided on the command line. The user is now prompted whether the configuration change should be applied to the current server or all servers in the group. Issue:2373 SF#:1370
Address an issue where the Unique Attribute Plugin incorrectly detected conflicts when under heavy. Issue:1873
Web Console displays a communication error alert when editing configurations objects if the server has been disconnected. Issue:2270 SF#:1239
Fix a bug in which the server and tool JVM configurations in java.properties would lack -Xms and/or -Xmx options if the amount of memory specified as the maximum heap size was not available when setup was run. Issue:890
Fix a bug in which setup fails if the 'locks' directory is missing, setup erroneously indicated that the server was running.
Fix a bug that prevented the display in dsconfig and the web console of configuration objects whose name contained a slash character. Issue:2244 SF#:1373
Update the directory server to allow attributes marked with NO-USER-MODIFICATION to be set if the Replication Repair Control (1.3.6.1.4.1.30221.1.5.2) is included in an add operation. This functionality was already available if the Ignore No User Modification Control (1.3.6.1.4.1.30221.2.5.5) was provided in addition to the Replication Repair Control. Issue:2361
Modify the update tool to disallow the update tool from being used from a package in which setup has been run. Issue:2464
Provide a custom title renderer that escapes configuration object names in the web console. This avoids a theoretical security concern with configuration object names that contain embedded JavaScript. Issue:2454
Fix a bug in the ldapmodify command-line tool that caused it to incorrectly treat a 'referral' result as success. Referrals are still not supported by this tool, but it will now treat them as a special kind of error and will provide a more useful message. Issue:1062
Update the status command to include information about the replication changelog database. Issue:2449
Update the UnboundID work queue configuration so that it is not possible to configure a value of zero for the number of write queues. Previously, if a nonzero number of write worker threads was configured with zero write queues, then the server would encounter an error and would be unable to start. Issue:2119
Update the local database backend so that if an index is found to be in a degraded state, it will now include both the backend ID and base DN in the message that is generated in addition to the name of the affected index. Previously, the message would only include the index name. Issue:2445
Online import-ldif now supports the --skipFile argument. Issue:841 SF#:00001350
Fix an issue, where in some cases, the Directory Server shutdown process was significantly delayed because of an improper shutdown of a replication related thread. Issue:2430
Generate a warning message at startup if the server is unable to determine the IP address or hostname of the local system, or if the local system's hostname resolves to a different IP address. These conditions may indicate a problem with the system configuration that could cause certain server components to break or function abnormally. Issue:2318
Creating an additional local database backend no longer generates severe warning messages in the server error log about degraded indexes. Issue:1113
Change the way that the serverUUID value is generated so that it is based on a combination of the system's primary IP address and the canonical server root path. This can be used to help detect cases in which a new server instance is created by copying the files associated with an existing server instance, which would have previously created two instances with the same serverUUID value. In the event that the stored serverUUID does not match the generated value, a log message will be generated to warn administrators of the change, and the newly-generated UUID will continue to be used. Issue:2470
Fix a NullPointerException error that could result from the use of targetscope="onelevel" in an ACI. Issue:2404
The import-ldif tool now verifies that the LDIF file argument is specified as an absolute path in case of an online import. Issue:2385
Fix a bug in the audit logger where the value of binary attributes could show up incorrectly when the audit logger was configured with use-reversible-form=true. Issue:2472
Remove support for the --append option of import-ldif since it was frequently used incorrectly, and in many situations led to situations that were difficult to recover from. Bulk adding entries to a backend that already has data can be done using the ldapmodify or parallel-update commands. Issues:1916,2427,54 SF#:00001299
Fix a bug that refused all writes to a backend when the write-ability mode was set to internal-only. Issue:949
Update the dbtest tool messages to make it clear that only backends of type local DB are supported. Issue:2436
Fix an issue where referential integrity fails when an entry referencing a deleted entry contains two attributes being managed by the referential integrity plugin. Issue:2365
Change the backend finalizers to run in parallel during shutdown to speed up the shutdown process. Issue:2110
Prevent cleaner and checkpoint threads from being interrupted before backend environment is closed. Issue:2020
Update the server to make it possible for change subscription handlers to be notified only of changes on a particular set of change subscriptions. Previously, change subscription handlers would always be notified of changes to any change subscription defined in the server. Issue:2475
Fix an issue when performing a modify operation to create an ACI that returned a result of Insufficient Access Rights instead of Invalid Attribute Syntax when the aci attribute was malformed. Issue:2477 SF#:1376
Fix a bug that could cause incorrect behavior for unindexed searches with a base DN equal to a base DN of the backend if one or more common-compact-parent-dn values were defined for entries below that base DN. In that case, only entries in the backend but not below any of the defined common compact parent DNs may be returned. Issue:2481 SF#:00001380
Improve the output of the ldapsearch tool to mention that a password has expired when the bind occurs. Issue:1981 SF#:1227
Fix a bug that prevented updating a user entry that needs a password change. Issue:2492 SF#:9999
Fix a bug where a virtual attribute rule based on group membership could cause the server to shut down. Issue:2434
Modify the updater so that the --ignoreWarnings option can be used to continue with update when there are warnings related to version compatibility issues. This allows an update to be run in a non-interactive environment, such as a script. Issue:2495
Set the autocomplete flag on the login form of the web console to be explicitly set to false. Issue:2496 SF#:1383
Update the audit logger to use the filtering criteria specified in the configuration. Issue:2443
The admin alerts list no longer includes alert types that are clearly not applicable to the product. Issue:1738
Update generated command line arguments (such as for dsconfig) to be quoted in a mechanism specific to the operating system where they are generated and to eliminate all escaping with \, which had caused problems when replaying certain commands. This is done with as much portability across systems as possible. Issue:2455
Update the server to improve its behavior when dealing with attribute types that were switched from user to operational, or vice versa. In such cases, existing entries would treat them as user or operational based on the state of those attributes at the time the entry was written and as such operations involving those attributes may behave incorrectly. Issue:2546 SF#:00001379
Fix a bug that made it possible to re-use a password in the password history using ldappasswordmodify. Issue:2497
Enabling replication between the current and prior version of the product may cause schema initialization problems. The code has been updated so that configuration schema elements are not overridden when enabling replication. When adding a Directory Server to a replication topology running a prior version of the product, it is recommended to use a server from the topology as the first server of the dsreplication command. Alternatively, schema replication may be excluded during dsreplication enable by using the --noSchemaReplication argument. Issue:2555
Improved status command output to better inform the user of how the local server status was determined, based on the arguments provided. Issue:2487
Cap db-evictor-critical-percentage configuration for backends so that the total cache percentage never goes above 90%. Issue:2285
Update cli documentation to include new commands for updating and reverting a server installation. Issue:2573 SF#:1390
Update the Directory Server to add support for sensitive attributes, which can be used provide an additional layer of protection to avoid leaking data that might be considered sensitive. It is possible to reject add, compare, modify, or search requests which target sensitive attributes, or to restrict them so that they may only be allowed over secure connections, and it is also possible to always strip those attributes out of entries returned to the client, or to allow them to only be returned to clients using secure connections. Issue:2412
Tools using a scope argument are now correctly documented in the CLI documentation. Issue:2594
Several enhancements to the Periodic Stats Logger: all columns in the output can now be turned on/off, many more built-in metrics are available to be logged, and additional custom metrics driven off of cn=monitor entries can be added by creating Custom Logged Status objects. Issue:2039
The naming of the replication domain configuration has been updated to facilitate scripted installations by removing the replication domain ID from the name. Issue:2245
Fix a bug that did not use the password policy during an add operation if it was assigned using a virtual attribute. Issue:2622 SF#:1398
Fix an issue in the Directory Server which would cause ldap-diff to miss entries from a subordinate local DB backend when the scope of the comparison includes more than one local DB backend. This could be the case for an entry-balanced Directory Server. Issue:2618
Fix a problem where import-ldif would never finish if entries were rejected with invalid attribute syntax. Issue:2514
Change the way abandon and cancel requests are run in order to prevent request handler threads from being detained while these operations wait to get back results. Issue:2631 SF#:1395
The server now issues an alert when it has begun the startup process. Issue:2642
The server now issues an alert when a JVM pause (possibly due to garbage collection) has been detected. Issue:2637
The web console now allows the specification of multiple LDAP servers to be used for authentication and discovery of topology servers. Issue:2466
The web console now supports specification of a server from its login page. Issue:2190
In case a replica is backlogged, the Directory Server is supposed to issue an alert. The Directory Server is also expected to delay completing the startup until the size of the backlog (if any) has been determined. In some cases, the Directory Server did not issue an alert before the startup had completed. Issue:2662
The entry checksum virtual attribute provider has been extended to allow excluding attributes from the checksum calculation. The provider has also been updated to ignore the insertion order of attribute values when calculating the checksum. Checksums of two identical entries used to differ if the values of at least one multi-valued attribute had been added in different order. Issue:1156
The import-ldif tool new features option --addMissingRdnAttributes which when present will silently add attribute/values from the RDN components of the DN that do not appear in the set of attribute values for the entry. When this option is not present, import-ldif will now reject such entries. Issue:2612
Update the ldappasswordmodify tool to supply the bind password as the user's current password when making a self-change. This is convenient when making a root user password change so that the current password does not have to be specified twice in the command line arguments. Issue:2525
Provide better descriptions in the MIB for SNMP trap variable bindings. Issue:2508
Fix an issue where explicitly requested attributes would not be returned when an access control rule allowing access to them contained a target filter on an attribute that was not one of those requested. Issue:2564
The file-based loggers now optionally support millisecond level precision. Issue:2603
Fix an issue where the referential integrity plugin would not perform all the appropriate actions for all kinds of ModifyDN operations. Issue:2498
Fix an issue where stop-ds on a replicated server could hang after logging an error indicating that the Replication Server db thread had exited while holding one or more read locks. Issue:2668
Added a "invoke-gc-day-of-week" property to the Periodic GC Plugin so that it can be configured to run only on certain days of the week. Issue:2660
Update the Periodic Stats Logger so that on shutdown it logs stats from the final interval. Issue:2684
Add an option, db-compact-key-prefixes, to the Local DB Backend. This exposes a new feature of BDB JE 4.1.6, which leads to a reduction in the memory needed to cache the database. It defaults to true. Issue:2693
If there are only two replicated servers in the topology, then dsreplication disable subcommand will disable replication on both servers. The disable subcommand will only target the specified server if there are more than two replicated servers in the topology. Issue:1794
Improve output when JVM errors occur in scripts used to set up environment for command line tools. Issue:2172
Fix a bug in the restore tool that could prevent it from operating in "dry-run" (used to verify a backup without restoring it) mode with the server online. Issue:2692
Update the default JVM arguments to improve garbage collection tuning.
Update dsjavaproperties to validate that all java-home properties specified in config/java.properties reference valid Java installations. Issue:2719
Fix an issue where the alerts backend could write an incomplete LDIF backing file if an error were to occur during the write. Also, if an error in the LDIF file is discovered when the server is started, the alerts backend will now read as much as it can from the file and preserve a copy of the bad file. Issue:2700
The dsreplication initialize, initialize-all subcommands have been updated to detect if the source server has active unavailable alerts. In interactive mode, these utilities will display a warning and will not allow the user to select these servers.
The dsreplication status subcommand has been updated to display a warning about any server that has either unavailable or degraded alerts. These servers may not be displayed and may affect the reported number of missing changes. Issue:2707
Add support for logging intermediate response messages that are returned to the client. Intermediate response logging will be enabled by default, but may be disabled if desired. Issue:2428
Modify the import-ldif tool to help guard against accidentally overwriting existing backend data. The new -r/--overwriteExistingEntries option must be present when performing an import into a backend with a branch that already contains entries (although the option need not be present if a branch contains just a single base entry). It should be noted that existing scripts that perform an import-ldif may need to be modified to include this option in order to function as before. Issue:2478 SF#:00001378
Fix a bug where the web-console's schema editor could write object class definitions to the server that did not include the object class's type. This occurred when no attempt to change the default value STRUCTURAL was made in the object class creation dialog. Issue:2749
The dsreplication remove-defunct-server command used to remove the defunct server from the server registry when an incorrect replication port was provided even though the displayed message suggested otherwise. The remove-defunct-server subcommand also used to refuse defunct server replication port argument values larger than 32767. Issue:2751
Address an issue with the web console where it would not allow read-only configuration properties to be set when an object was initially created. Issue:2730
These issues were resolved with version 2.2.0.0 of the Directory Server:
Add support for an LDAP join control, which can be used to provide an SQL-like join capability which can be used to request that the server return other entries which are related to entries matching the initial search criteria. Issue:1012
Modify the command-line argument parsers to generate a warning message if an argument value is the same as the short or long form for another argument. This can help prevent users from forgetting to supply a value for an argument which requires one. Issue:944
Streamline the process for sending responses to LDAP clients to use a stream-based approach and avoid the creation of a number of intermediate objects.
Add support for the permissive modify request control, which may be used to allow a modify operation to succeed even if it tries to add a value which already exists or remove a value which does not exist. Issue:131
Change the way that search result entries are prepared for return to the client to make the process more efficient and create less garbage.
Update the access log format so that result log messages for operations containing certain controls will include information about that control. For the assertion request control, the assertion filter will be provided. For the matched values request control, the matched values filter will be provided. For the pre-read, post-read, and get authorization entry request controls, the requested attributes will be provided. For the join request control, the join rule (including nested join rules) will be provided. For the server-side sort control, the sort order will be provided. For the virtual list view request control, the offset or assertion error, before count, and after count will be provided. For the simple paged results control, the page size will be provided.
Update MakeLDIF to add a "<random:timestamp>" tag that can be used to include a randomly-selected date from any time within the last ten years. It is also possible to use "<random:timestamp:min:max>" to specify the desired time range, where min and max should be given in the generalized time format. Issue:1083
Add a new configuration property for alert handlers that makes it possible to filter the types of alerts that should be processed based on the alert severity. By default, all types of alerts will be processed.
Provide a new alert handler that can be used to execute a specified command whenever an alert is generated within the server. The details of the alert notification will be provided as arguments when executing that command. The arguments will be provided in the following order: the name of the alert type, the OID for the alert type, the alert severity, the fully-qualified name of the Java class that generated the alert, the unique identifier assigned to that alert, and the text of the alert message. The alert handler will ensure that only one instance of the command may be invoked at a time to avoid problems from commands that aren't safe to run concurrently. If multiple alerts are generated concurrently, then they will be queued and the command will be executed sequentially for each of them. Issue:1146
Update the ldapsearch and ldapmodify tools so that in the event that an error response is received from the server, the diagnostic message from that error response will be displayed to the user rather than the generic error message that had previously been used.
Add a new error log alert handler, which makes it possible to control which types of alerts should be logged (based on either the alert severity or specific alert type). Further, the severity of the log message will reflect the severity of the alert notification.
Update the collect-support-data tool to archive information about the upgrade history of the server installation.
Update the LDAP changelog so that changelog entries now contain createTimestamp, modifyTimestamp, creatorsName, and modifiersName attributes. This can be optionally disabled if desired. Issue:1163
Update the LDAP changelog to add support for searches using the persistent search request control.
Generate administrative alerts for any operation which results in a change to the defined set of access control rules in the server, including global ACIs. Issue:1203
Improve the mechanism used to automatically tune the number of database lock tables. It will now be more scalable on systems with more than 100 CPUs, and will operate correctly for work queue implementations which do not have an explicit number of worker threads.
Update the cursor-across-indexes method of priming the backend so that it can use multiple threads to prime separate databases concurrently.
Modify the enter-lockdown-mode and leave-lockdown-mode tools to allow them to connect to any local address rather than requiring the request to be sent over the loopback address. Issue:1144
Fix a bug that could cause replication to be halted if the replication window size was changed in a manner that was not coordinated across all servers. Issue:1235
Provide the ability to force an explicit garbage collection on startup if the initialization of any request processor takes longer than a specified period of time. This can help improve garbage collection behavior in the Directory Proxy Server when a global index is enabled and automatically primed on startup.
Update the LDAP connection handler to disable TLS renegotiation by default, which can eliminate a vulnerability in which a man-in-the-middle could potentially inject arbitrary cleartext between TLS negotiation and initial data from the client.
Allow the Berkeley DB checkpoint interval to be altered within the server configuration. It was previously hard-coded at 60 seconds.
Avoid setting the "-XX:ParallelCMSThreads" JVM argument on systems containing a single CPU. This option has been observed to cause the JVM to fail to run properly, particularly in virtualized environments. Issue:1300
Update the active operations monitor entry to include attributes which provide the number of operations and persistent searches currently in progress within the server.
Fix a potential problem in replication that could result in the servers becoming out of sync in the event of conflicting add operations performed on different servers concurrently. Issues:655,655
Update the UnboundID work queue to change the default capacity from unlimited to 1000 operations, and to add the ability to block for a specified period of time (up to 60 seconds by default) if the work queue is full before giving up and rejecting the operation. This can help prevent clients using asynchronous requests from being able to continually enqueue requests without bound.
Update the server to provide the ability to keep track of the length of time that an operation was required to wait on the work queue before being picked up for processing by a worker thread. This can be used to identify cases in which client threads were forced to wait for a long time for a worker thread to become available, which may indicate a configuration problem or problems due to an inefficient client. It is also possible to define the maximum length of time that an operation may be allowed to wait on the work queue before being rejected with a "busy" response. If queue time monitoring is enabled, then it will appear in access log messages and in the processing time histogram monitor entry, and it may be used in simple result criteria objects.
Add support for creating a special type of equality indexes which include an optional filter such that the index will only be used for search operations whose filter contains the target filter, as well as an equality component including the target attribute.
Update the work queue monitor entry to include a num-busy-worker-threads attribute which indicates the number of worker threads that are in the process of actively processing a request rather than waiting for new work to do.
Add a new Periodic Stats Logger plugin, which can be used to write various server statistics to a file in CSV format with detailed information about processing that occurred within the Directory Server or Directory Proxy Server, as well as the JVM in which the server is running, within the interval since the last update.
Update the server so that it will return a result of "unavailable" rather than "unwilling to perform" for operations from unauthorized clients when operating in lockdown mode.
Add a number of new access loggers to the server configuration which may be used to troubleshoot problems in the server. One will log information about any operation which did not complete successfully to the logs/failed-ops log file. Another will log information about any operation which takes more than 1000 milliseconds to complete to the logs/expensive-ops file. Another will log information about search operations which did not return any entries to the logs/searches-returning-no-entries file. Of these new loggers, only the one writing to the logs/failed-ops file is enabled by default.
Update the UnboundID work queue to add support for maintaining separate pools of worker threads for read and write operations, which can help minimize the performance impact for read operations in the event that write operations are temporarily blocked by expensive processing (e.g., database contention, I/O backlog, etc.). It is also possible to split worker threads across multiple internal queues for reduced contention. This has been observed to provide significantly improved performance on systems with large numbers of CPUs.
Fix a problem which could cause a replication conflict if two modify DN operations were processed in immediate succession in such a manner that the second operation attempted to rename an entry so that it held the same DN as had previously been used by the entry targeted by the first modify DN operation.
Update the system information monitor entry to include information about the system account being used to run the server and a list of all system properties defined in the JVM.
Update the UnboundID work queue to provide the ability to select the type of queue to be used. Also, update the LDAP connection handler to provide the ability to create a separate request handler thread for each connection, rather than allowing request handlers to potentially read requests from multiple clients.
Add the ability to request that changes written to the server audit log be formatted in a reversible form, such that it will be easier to see exactly what change was made, and revert to the previous values used within the entry if desired. In some cases (e.g., modify DN and delete operations), comments may be used to provide information about the previous state of the entry. Issue:970
Add support for a number of different types of resource limits within the server, including: the maximum number of connections that may be established at any given time, the maximum number of concurrent connections from any client (based on either IP address or bind DN) or group of related clients, the maximum number of operations that may be processed over the life of a client connection, the maximum number of operations that may be processed concurrently for a single client connection, the maximum rate at which a single client or a group of related clients may request operations, the maximum length of time that a client connection may remain established, the types of request controls which may be used, the types of search filters which may be used, the minimum number of characters required in substring filters, and caps on resource consumption allowed during search operations.
Add the ability to compress replication communication between servers. Compression will be enabled by default when communicating with a nonlocal replication server. Issue:1319
Update the dbtest tool to add an option to the list-database-containers subcommand that makes it possible to list information about only a single database. This can help improve the ability to use the tool efficiently in an environment with a very large number of entries.
Add a new global configuration option which makes it possible to specify the maximum length of time that the server shutdown process may take before it attempts to interrupt threads which have not yet completed their processing. In most cases, server threads will react to a shutdown in a timely manner and no interrupt is needed.
Improve the shutdown process so that it is less likely to interrupt database threads in a way that could require a lengthy recovery process at startup. The shutdown time has been improved in the general case, and in the abnormal case the server is more patient and will wait for a longer period of time to allow for a graceful shutdown, periodically providing information about the threads that are still running. Issues:1559,1583
Make a change to the UnboundID work queue in order to provide a small performance improvement.
Update the Directory Server so that access log messages for extended operations now include human-readable names for the operation type in addition to the numeric OID when possible.
Fix a bug in the parallel-update tool that could cause operations to be retried even when the --neverRetry argument was provided. Also, when the tool is configured to retry operations, the reject file will now include the result code and diagnostic message received from the last failure after no more progress can be made, rather than providing a generic message.
Fix a bug in the collect-support-data tool that could cause it to make incorrect use of a password file when capturing the output of the status command. Issue:1593
Update the alert generated in the event of a replication backlog so that it no longer counts replicas that are in the process of being initialized. Issue:1123
Update the SNMP alert handler so that the traps it creates have a more sensible value for the uptime field. Previously, the uptime value was always zero, but it will now reflect the length of time that the Directory Server has been online.
Improve the accuracy of the update-sent and update-received attributes in replication server handler monitor entries.
Fix a problem in which percentages logged during online replica initialization were incorrect after approximately 21 million entries had been processed. Issue:1612
Fix a bug in which LDAP request handlers might not properly close the selectors used to read requests from clients. This could cause a memory leak over time, particularly in servers configured to use the request-handler-per-connection option.
Improve the access log message generated whenever a connection is terminated because of a decoding error encountered while reading data from the client. The message will now include the contents of the packet received from the client, indicating the point at which the problem was encountered.
Update the replication mechanism to improve the order in which changes are replayed, and to adjust the use of locking in the replay process to improve the mechanism for ensuring that dependencies between changes are properly upheld. Issue:900
Fix a bug in the LDAP connection handler in which the server could incorrectly handle a request in which the ASN.1 length of the LDAP message was encoded using multiple bytes that were split across separate packets.
Fix a bug in which a search operation which was part of an interactive transaction might not use the corresponding database transaction for part of its processing.
Update the Directory Server to provide the ability to re-try the process of generating the index candidate list in the event of a timeout on the first attempt. Previously, if such a timeout occurred, then the server would proceed with the search as unindexed, which could be very expensive.
Improve the process for stopping threads when the server is shutting down, and provide additional debugging information that may be useful if any threads are slow to stop running. Issue:900
Update the ldap-diff tool to take advantage of the stream directory values extended operation when it is available. This can dramatically improve the performance of the tool when attempting to identify the set of all entries in the server. Issue:794
Update the Directory Server to make replication conflict entries invisible under normal circumstances. They will now only be visible in base-level searches, if the filter contains an equality component of "(objectClass=ds-sync-conflict-entry)", or if the request includes a control with OID 1.3.6.1.4.1.30221.2.5.13. Issue:1660
Update the unique attribute plugin so that it will ignore any replication conflict entries when attempting to determine whether a particular attribute value is already in use within the server. Issue:1661
Fix a bug in the implementation of the stream directory values extended operation that could cause it to fail to work properly across subordinate backends.
Update the ldap-diff tool to provide support for reading the DNs of all the entries in one or both directories from files instead of obtaining them over LDAP. In directories which do not support the stream directory values extended operation, this may provide a significantly faster way to obtain this information if it is already available in some form.
Fix a bug in the ldap-diff tool that could cause it to report incorrect percent complete values when comparing data sets of more than 20 million entries.
Change the default access log format to log only a single line per operation containing details of both the request and response rather than separate lines for requests and responses. In the case of the Directory Proxy Server, that single line will also include information about the backend server to which the request was forwarded, although forward failure messages will still be logged as separate lines by default. Issue:1677
Fix a problem that could cause problems with replication in the event that the base entry for a backend (which contains important replication metadata) is deleted. Issue:1003
Update the Directory Server to add support for interrupting the stream directory values extended operation in the event that the client connection is terminated or the request is abandoned or canceled.
Update a number of password storage schemes using salted digests to provide support for salts of arbitrary length rather than requiring them to use a fixed length. This can be useful for encoded passwords imported from external sources.
Fixed a bug in the dsreplication tool that could prevent it from adding a replica into the all-servers group if replication had previously been enabled but was subsequently disabled on that replica. Issue:1674
Fix a bug in the upgrade tool that could cause the same warning message multiple times if the version obtained from the server was different from what was expected (e.g., because a server jar file had previously been replaced without using the upgrade tool). Issue:1640
Modify the default work queue to make use of multiple queues by default, which can improve performance and scalability on multi-CPU systems.
Update the parallel-update tool to add the ability to use the permissive modify request control, which may be used to request that the server ignore attempts to add attribute values which are already present or remove attribute values which are not present.
Update the ldap-diff tool to make it more likely that its output can be replayed without any alteration. The order of operations has been updated so that all deletes are listed first, followed by all modifies, and finally all adds. In addition, all delete operations are ordered such that subordinate entries will always be removed before their ancestors.
Update the implementation of the CRYPT password storage scheme to provide support for the 256-bit and 512-bit SHA-2 digests in the format used by the Linux and Solaris crypt tool. This may make it easier to import existing passwords from accounts in a Linux or UNIX environment.
Update the Directory Server to improve the ability to interrupt the process for priming backends if an attempt is made to abort the startup process.
Update the scripts used to stop the server to prevent them from falling through to try to stop the server over LDAP if the attempt to kill the process fails or times out, since the attempt to stop the server over LDAP would fail without at least the appropriate authentication credentials, and could potentially be dangerous in some contexts.
Change the process for selecting the salt used to encode passwords during LDIF import processing so that the salt is computed in a deterministic manner but that will be different for every entry. This makes it possible to preserve resistance to dictionary attacks while ensuring that passwords will be encoded in a consistent manner if the same LDIF file containing clear-text passwords is imported into multiple servers. Previously, this could cause problems if attempts were made to establish replication between those servers. Issue:1142
Update the system information monitor entry to include information about all environment variables defined in the server process. In addition, it will now attempt to determine and report the process ID of the JVM in which the server is running.
Update the logic for sending an e-mail message from the server so that it will always attempt to determine the fully-qualified name of the system to include in the HELO/EHLO request. In the event that the fully-qualified name cannot be determined, then the IP address of the server will be used rather than using an unqualified name. Issue:1337
Update the server to make it possible to configure the length of time that name-to-IP address mappings may be cached within the server. This may be useful in environments in which the addresses associated with a particular hostname may change frequently. Issue:941
Update the upgrade and revert-upgrade tools to ignore directories that contain backup files. Issue:1143
Update the schema backend to make it possible to replace the schema using an LDIF import, and to fix a problem that could occasionally cause multiple values to be reported for the createTimestamp and modifyTimestamp attributes. Issue:1441
Update the Directory Server to change the implementation of the show-all-attributes configuration option in the schema and root DSE backends to be more robust, particularly for clients requests explicitly requesting a specific set of attributes. Issue:1590
Updated the logic used to identify previous log files that had been rotated so that only files with names that might have been created by the rotation process will be candidates for removal by the retention policy. Issue:1285
Update the Directory Server to add a search shutdown plugin which can be used to perform a specified internal search when the server is shutting down and have the results of that search written to a specified file. This may be useful, for example, to automatically dump the contents of the monitor backend on shutdown. Issue:1334
Fix a potential bug in the access control handler to correct its behavior for access control rules with a deny action without any target attribute specification. Issue:1269
Update the server so that when creating a duplicate of an existing configuration object, some key properties may be excluded from the clone so that they must be explicitly configured by the administrator rather than automatically using the same value as the object being duplicated. This can help prevent problems in which a duplicated value was inadvertently used. Issue:1675
Add support for a new CLIENT-CERTIFICATE access log message type which can be used to log information about any certificate presented by a client when negotiating a secure communication channel. Issue:1756
Update the Directory Server to provide an option to automatically authenticate clients that have presented their own certificate during SSL or StartTLS negotiation. This option is disabled by default. Issue:1748
Update the replication mechanism to generate an administrative alert if too many outstanding changes are detected at startup. In addition, the server will place itself in a degraded operation mode until the backlog has been reduced below a configured threshold. Issue:1606
Fix a bug in the upgrade tool that could cause it to behave incorrectly if the server contained custom extensions. Issue:1469
Fix a bug that may cause intermittent failures for search operations with large result sets when SSL or StartTLS is in use. Issue:1330
Update the replication server to provide the ability to listen for communication with other replication servers only on a specific address rather than all addresses associated with the system. Issue:940
Fix a bug in replication monitor entries that could cause the server to incorrectly report that another replica was up to date if a response could not be obtained from that replica in a timely manner. The monitor will now reflect the last known state of that replica rather than always reporting that it is up to date. Issue:1607
Add a plugin which may be used to allow the server to act as an SNMP sub-agent rather than requiring it to always operate only as a master agent. Issue:1723
Update the Directory Server to fix a bug that could interfere with the ability to use compressed communication with replication servers. Issue:1708
Update the Directory Server so that the firstChangeNumber and lastChangeNumber attributes are included in the set of operational attributes which may be treated as user attributes if the show-all-attributes option is enabled. Issue:1825
Fix a bug in the server in which the namingContexts attribute of the root DSE could incorrectly contain DNs which are subordinate to other DNs already present in the list of naming contexts (e.g., if the server is configured with subordinate backends or nested subtree views).
Update the server to generate an administrative alert when starting or completing an index rebuild, and to mark that server as degraded while the rebuild is in progress. Issue:1603
Update the Directory Server to add official support for LDAP transactions as defined in RFC 5805. This implementation is identical to the existing support for batched transactions, but now uses the official OIDs for the controls and extended operations as defined in the RFC. Issue:1811
Add a tool which may be used to dump the DNs of all entries below a specified base DN in the server. This tool uses the stream directory values extended operation and may therefore operate in a very efficient manner.
Update the setup process so that the server will be configured without an LDAP connection handler if the "--no-prompt" argument is provided without an "--ldapPort" argument. This option is only available for use when using the non-interactive setup mechanism. Issue:1759
Update the server to improve logging performance under heavy load, particularly on systems with relatively slow single-threaded performance.
Update the replication mechanism to help avoid cases in which a replication server may be flooded with the same set of changes from multiple servers after being offline for an extended period of time. Issue:1815
Change the behavior of the dsconfig tool when creating a new configuration object so that the user will first be prompted about whether to create a completely new configuration object or clone an existing object. This simplifies the interface and makes it less likely that an administrator will incorrectly attempt to clone an existing object rather than creating a new one. Issue:1747
Fix a bug that could potentially cause an error message to be reported when attempting to access a database in read-only mode when that database did not contain compaction information for all base DNs associated with that backend. This could cause unexpected errors in some rare corner cases (e.g., attempting to perform an LDIF export of a backend that has never been initialized and does not contain any database files). Issue:1114
Update a number of access log retention policies to make them more robust and to fix bugs that could prevent old log files from being removed when the appropriate conditions were met. Over long periods of time, this could potentially cause available disk space to run low and necessitate the manual removal of files to avoid running out of space. Issues:1867,1867
Update the dsreplication tool so that when operating on an existing server (e.g., to initialize or disable a server), the user is allowed to choose the target server from a list rather than being prompted to enter all of the information for connecting to the server. Issues:1613,1893
Update the Directory Server to add the ability to limit the number of unindexed searches which may be in progress at any given time. This can help avoid problems in cases in which unindexed searches may be occasionally required if the client issuing those searches does so too frequently and consumes all available worker threads.
Update the Directory Server to make it possible to prioritize the way that information is stored in the database cache. It is now possible to indicate that contents of some system or attribute indexes should be considered high priority, while the contents of others should be considered low priority or perhaps not cached at all. This capability may be useful to achieve optimal performance and memory behavior on systems which do not have enough memory to fully cache all database contents.
Modify the upgrade process so that schema definitions are always migrated before the configuration. In some rare cases, attempting to migrate the configuration before the schema could lead to failures in the upgrade process. Issue:1812
Update the server to include more useful information in access log messages reporting the closure of a client connection as a result of an I/O error.
Update the changelog backend so that changelog records for deleted entries may include the values of a specified set of virtual attributes associated with an entry at the time it was removed. Issue:1897
Fix a bug in the Directory Server in which it could potentially return entries that were outside the requested search scope when processing a search across subordinate backends. Issue:1934
Fix a potential problem in the replication server that could cause attempts to communicate with other replicas to fail if any of them were in a state in which they accepted TCP connections but did not respond to any communication attempts. Issue:1434
Fix a potential bug in replication that may cause delete operations made in quick succession to be replayed in an incorrect order in a manner that could result in failures if those entries had a hierarchical relationship. Issue:1701
Update the repeated characters password validator to provide the ability to reject a password if it contains multiple consecutive characters from the same character set, rather than only rejecting passwords with the same character repeated too many times. Issue:1940
Add support for a new regular expression password validator which can be used to require that all passwords match a given pattern, or to reject any password which matches a given pattern. Issue:1941
Update the dsreplication tool to better handle scenarios in which the name provided by a user to reference a server does not match the name stored for that server in the administration data repository. Issue:1613
Modify the upgrade tool so that it will not attempt to initialize the replication subsystem during upgrade processing. Issue:1953
Update the Directory Server to fix potential problems in its support for SSL or StartTLS communication if the server was not able to access a complete block of encrypted information at once. Issue:1330
Fix a bug that could prevent a disabled access logger from being removed from the server configuration.
Update the server to prevent multiple loggers from being configured with the same target log file. Issue:1676
Update the Directory Server so that it will generate an administrative alert if an attempt to initialize a backend fails. Previously, this would have resulted in a message written to the error log but would not have caused an administrative alert. Issue:1475
Update the Directory Server to add the ability to identify that some databases within a backend should be primed in their entirety while others should have only their internal nodes primed.
Update the Directory Server to introduce a significantly more compact encoding for the index which correlates entry DNs and entry IDs.
Update the Directory Server to add the ability to prime the contents of a backend to the filesystem cache using non-sequential reads in a manner to attempt to overcome the limitation imposed by filesystems like ZFS that prevent extended sequential reads from being cached. Also, make it possible to configure multiple prime methods for a single backend.
Significantly revise the upgrade tool in an attempt to make it more robust and minimize the amount of work required for performing an upgrade. Issues:1927,1931,2031,2037
Add support for a new search-and-mod-rate command line tool which operates in a manner similar to the searchrate tool but that will also modify any entries returned from the search.
Modify the way that the Directory Server compresses entries for storage in the JE backend. The previous implementation caused the server to consume a significant amount of memory, which eliminated any potential benefit of compressing the entries.
Fixed a potential bug in the way that the search time limit is enforced that could cause a time limit exceeded result to be returned too soon in a rare corner case.
Update the Directory Server so that access log messages for replicated changes may optionally include the replication change number.
Rename the upgrade tool to be "update", and rename the revert-upgrade tool to be "revert-update".
Update the Directory Server to add support for removing replication artifacts from the server. A new "-R" option has been provided to the export-ldif tool that can cause the resulting LDIF file to exclude replication state information, and a cleanup-local-server tool has been added that can be used to remove all replication-related information from the configuration, schema, and server registry. Issue:1913
Update the dsreplication tool so that when disabling replication in a server, all replication state is removed from disabled backends and removes historical values from the server registry. Issue:1913
Update the Directory Server to fix a bug in access control evaluation that could cause evaluation to be performed incorrectly for filters containing a NOT component. This may cause the server to incorrectly prevent clients from seeing search result entries that they should be allowed to access. Issue:1757
Update the Directory Server to log information during task processing that may not have been previously captured in the task entry. This primarily impacted LDIF import and export tasks, and index rebuild and verify tasks.
Update the Directory Server to correctly handle delete operations which included the subtree delete request control. Issue:2066
Update the Directory Server to provide the option to use a dedicated evictor thread for evicting content from the database cache. This may help provide better and more consistent performance in environments which do not have enough memory to fully cache all database contents.
Update the Directory Server so that it will prefer to connect to a co-resident replication server under most conditions rather than connecting to an external replication server instance. Issue:1946
Update the Directory Server to make the lockdown-mode privilege usable by non-root users. Issue:1109
Update the server so that it includes a patch version number in addition to the existing major, minor, and point version numbers. This can help better distinguish versions with the same major, minor, and point version numbers which differ only based on patches applied.
Update the Directory Server to abort the startup process with an error message if the admin data backend includes a malformed entry. Previously, malformed entries in the admin data backend would be silently ignored. Issue:2049
Update the Directory Server to make the online replica initialization process significantly more efficient. Issue:1915
Update the dsreplication tool to warn the user if the supplied hostname is not fully qualified, which may cause problems in environments with multiple subdomains. Issue:2093
Update the Directory Server so that the schema backend uses a new 99-schema-backend-state.ldif file to store state information rather than including it in 99-user.ldif. Issue:1056
Fix a problem with the way that schema replication could be performed if the schema was modified with the server offline and those modifications included malformed schema elements. Issue:986
Update the collect-support-data tool to change the way that the jstack tool is invoked to dramatically reduce the impact that it has on the running process. Issue:2038
Update the Directory Server to add the ability to collect high-precision timing for various phases of operation processing. A new operation timing access logger is available that can be used to get access to this information.
Update the access logger so that updates to replica state information in the base entry for a replication domain are excluded by default. Issue:1804
Update the dsreplication tool so that it is less likely to incorrectly warn an administrator that the initialization process has hung. Issue:1952
Update the export-ldif and verify-index tools so that they can be used against a server whose database files are contained on a read-only filesystem, including a ZFS snapshot. Issue:71
Update the Directory Server to dramatically improve the performance exhibited when making topology changes to a large replication environment. Issue:2061
Update the Directory Server to add the ability to monitor the process of opening a Berkeley DB Java Edition environment for a backend. In the event that the open process takes a significant amount of time (e.g., because a database recovery is in progress), the server may notify the administrator that startup is still active and directs them to the JE log file for potential information on the progress for opening the environment. Issue:967
Update the alert backend to be able to handle entries with unrecognized alert types. This is unlikely to occur in normal conditions, but could cause a problem in deployments in which the server was upgraded and subsequently reverted, and an alert was generated in the upgraded server that uses an alert type not defined in the older version. Issue:2126
Change the way that the worker thread percent busy values are calculated in the work queue monitor entry to make them more accurate. Also, add new recent-average-queue-size and current-worker-thread-percent-busy monitor attributes. Issue:1982
Update the Directory Server to require Berkeley DB Java Edition version 3.3.100.
Update the Directory Server to provide the ability to detect the addition of new tools when updating from one version to another. If one or more new tools are provided, the java.properties file will be updated to provide an appropriate JVM configuration for them. Issues:2148,2150
Update the dsreplication tool so that the status subcommand includes the ability to determine if an external initialization is in progress. Issue:1309
Add a new pre-parse bind plugin that can be used to intercept a simple bind request and convert it to a SASL EXTERNAL bind under the appropriate conditions. This may be necessary to provide compatibility for some broken LDAP clients (in particular Microsoft Outlook) which expect the server to automatically authenticate the client using the provided certificate and then ignore any subsequent anonymous simple bind.
Update the Directory Server so that it will generate an administrative alert and place the server in a degraded state if a failure is encountered while initializing the replication server. Issue:2052
Modify the update process to require that the system user performing the update is the same as the system user used to run the server. This will help prevent files from being created or altered during the update process with permissions that would prevent the server from being able to access them when the server is started as the appropriate user. Issue:2158
The SNMP MIB files have been moved to resource/mib. There are now no differences in the alert MIB provided with Directory Server and Directory Proxy Server. Issue:2170
Modify the update tool to ensure that the documentation is updated for the new release if appropriate. Issue:2178
Update the dsconfig tool and the Web administration console so that they inform the administrator of any administrative action (e.g., disabling and re-enabling the specified component, or restarting the server) that may be required as a result of a configuration change to be made. Issues:211,2132
Update the subject attribute to user attribute certificate mapper to provide support for VeriSign certificates whose subject contained an emailAddress attribute with an unusual encoding. Issue:2177
Update the Directory Server support for the LDAP join control to include a new reverse DN join rule type, which can be used to perform joins in which the target entries include a specified attribute with a value that is the DN of the source entry. Issue:2218
