UnboundID Identity Data Store Release Notes

Resolved Issues

These issues were resolved with version 4.5.1.6 of the Identity Data Store:

• Fixed the web console so that attempts to reconnect (after the console is restarted) succeed. Issue:DS-11043

• 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

Resolved Issues

These issues were resolved with version 4.5.1.5 of the Identity Data Store:

• Fixed a problem that could cause a VLV index to be improperly maintained in cases in which a large number of entries had exactly the same values for all of the attributes defined in the sort order. Issue:DS-10971 SF#:00002278

• 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

Resolved Issues

These issues were resolved with version 4.5.1.4 of the Identity Data Store:

• 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

• 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

• 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

Resolved Issues

These issues were resolved with version 4.5.1.3 of the Identity Data Store:

• 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

• 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

Resolved Issues

These issues were resolved with version 4.5.1.2 of the Identity Data Store:

• 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

• 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

• 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

• 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

Resolved Issues

These issues were resolved with version 4.5.1.11 of the Identity Data Store:

• 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

• 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

Resolved Issues

These issues were resolved with version 4.5.1.10 of the Identity Data Store:

• 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

• 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

New Features

These features were added for version 4.5.1.0 of the Identity Data Store:

• 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.

  • As required by the SCIM 1.1 REST API specification, bulk requests using the PUT, PATCH, or DELETE methods must include an operations.version value; existing client code may therefore need to be updated prior to enabling this feature.
  • Non-bulk modification requests (PUT and PATCH) must also specify the expected resource version via an If-Match header, according to the SCIM specification. However, the server does not enforce this.

Known Issues and Workarounds

These were known issues at the time of the release of version 4.5.1.0 of the Identity Data Store:

• 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

Resolved Issues

These issues were resolved with version 4.5.1.0 of the Identity Data Store:

• 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

New Features

These features were added for version 4.5.0.0 of the Identity Data Store:

• 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.

Known Issues and Workarounds

These were known issues at the time of the release of version 4.5.0.0 of the Identity Data Store:

• 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

Resolved Issues

These issues were resolved with version 4.5.0.0 of the Identity Data Store:

• 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:

  • identify-references-to-missing-entries -- This tool can help identify any entries which contain attributes whose values are DNs that reference entries that do not exist. This can be used in conjunction with server-side referential integrity support in order to ensure that there are no entries which reference nonexistent entries.

  • identify-unique-attribute-conflicts -- This tool can help identify any values for an attribute or set of attributes that appear in multiple entries when values of those attributes are expected to be unique. This can be used in conjunction with server-side unique attribute support in order to ensure that no conflicts exist.

• 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 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

New Features

These features were added for version 4.1.0.0 of the Identity Data Store:

• 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.

Known Issues and Workarounds

These were known issues at the time of the release of version 4.1.0.0 of the Identity Data Store:

Resolved Issues

These issues were resolved with version 4.1.0.0 of the Identity Data Store:

• 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 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

New Features

These features were added for version 4.0.0.0 of the Identity Data Store:

• 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 (formerly Synchronization Server)
  • Metrics Engine (name unchanged)

• Add support for uncached attributes, which can be used to indicate that certain attributes should be stored in a manner amenable for applying different cache settings. 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 includes support for a simple uncached attribute criteria that allows the administrator to specify the attribute types that should be uncached, optionally restricted to those attributes with at least a minimum number of values or total value size.

• Make it possible to configure the Identity Data Store 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 Identity Data Store 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.

• 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).

• 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.

• 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.

Known Issues and Workarounds

These were known issues at the time of the release of version 4.0.0.0 of the Identity Data Store:

• UnboundID RPMs do not support the "--relocate" option. However, the RPMs are relocatable using the "--prefix" option at install time. Issue:DS-7890

Resolved Issues

These issues were resolved with version 4.0.0.0 of the Identity Data Store:

• 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

New Features

These features were added for version 3.6.0.0 of the Identity Data Store:

• 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.

Known Issues and Workarounds

These were known issues at the time of the release of version 3.6.0.0 of the Identity Data Store:

• 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

Resolved Issues

These issues were resolved with version 3.6.0.0 of the Identity Data Store:

• 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

New Features

These features were added for version 3.5.1.0 of the Identity Data Store:

• 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.

New Features

These features were added for version 3.5.0.0 of the Identity Data Store:

• 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:

  • References and group memberships are severed as part of the soft-delete process and are not restored as part of undelete.
  • Replication support: soft-deleted entries are replicated to replication servers which support soft-deletes.
  • Proxy support: Soft-delete requests are fully supported through the UnboundID Proxy Server and with proxy servers running in entry-balanced configurations.
  • Client LDAP SDK support: The UnboundID LDAP SDK fully supports all of the soft-delete controls used to process soft-delete operations from client requests.
  • Server SDK support: Server plug-in extensions are able to inspect and make modifications to entries during the processing of soft-delete and undelete requests.
  • Audit log: Soft-delete requests will log soft-deleted entries in commented form to record the retained entry and not to indicate a permanent delete operation has occurred. Undelete requests are also commented in the log to indicate a soft-delete entry has been re-added to the directory.
  • Changelog: Soft-delete requests are logged as delete operations with additional information about the soft-deleted entry that was created. Undelete requests are logged as add operations with additional information about the soft-deleted entry that was undeleted. The changelog can be optionally configured to record modifications and permanent deletes of soft-deleted entries.
  • Monitoring: The server maintains two counters for soft-delete operations. The soft-delete-entry-operations count and the undelete-entry-operations-count counters hold the number of discrete soft-delete and undelete operations that server has processed since startup, respectively.
  • Automatic Soft Deletes: A Soft Delete Policy assigned to the soft-delete-policy property of the Global Configuration specifies a set of client connection criteria and/or client request criteria used to indicate that delete operations from these clients will be automatically processed as soft-deletes without the need for the Soft Delete Request Control to be present in the request. A delete request can bypass consideration for automatic soft deletes by adding the Hard Delete Request Control to the request.
  Limitations:
  • Upgrades to this release require an index rebuild to accommodate two new indexes which were introduced. An equality index on ds-soft-delete-from-dn and an ordering index on ds-soft-delete-timestamp were added to support the Soft Deletes feature. If indexes are not rebuilt on upgrade, the Server will log an error at startup that it is operating in a degraded state.
  • Only leaf directory entries can be soft deleted.
  • Soft-deleted users cannot bind to the Directory Server, change their passwords, or act as an alternate authorization identity.
  • The DN or RDN attributes of a soft-deleted entry cannot be modified; however, other non-operational soft-deleted entry attributes can be modified.
  • There is no process to trim or purge soft-deleted entries automatically.
  • Soft-deletes are currently supported for database backends and are not supported for file-based backends or the Large Attributes backend.
  • The Proxy Server access log does not record a soft-deleted entry DN value in the DELETE RESULT line for a soft delete operation and it does not record an undeleted-from DN value in the ADD RESULT line for an undelete operation.
  • The Proxy Server audit log does not record a soft-deleted entry DN for a soft delete operation, and it records an undelete-from DN for an undelete operation, but it does not comment out the line containing the value.

• 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.

Known Issues and Workarounds

These were known issues at the time of the release of version 3.5.0.0 of the Identity Data Store:

• 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

Resolved Issues

These issues were resolved with version 3.5.0.0 of the Identity Data Store:

• 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 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:

  • ds-auth-is-proxyable -- May be used to indicate whether the user account may or must be used as the target of proxied authorization. Allowed values are "allowed" (which indicates that operations may be proxied as this user), "prohibited" (which indicates that operations may not be proxied as this user), and "required" (which indicates that the account will not be allowed to authenticate directly but may only be accessed via some form of proxied authorization)
  • ds-auth-is-proxyable-by -- May be used to provide a list of the DNs of the users that will be allowed to proxy operations on behalf of the associated user.
  • ds-auth-is-proxyable-by-group -- May be used to provide a list of the group DNs whose members will be allowed to proxy operations on behalf of the associated user.
  • ds-auth-is-proxyable-by-url -- May be used to provide a list of the LDAP URLs that will be allowed to proxy operations on behalf of the associated user.
  • ds-auth-may-proxy-as -- May be used to provide a list of the DNs of the users that the associated user will be allowed to proxy operations as.
  • ds-auth-may-proxy-as-group -- May be used to provide a list of the group DNs whose members the associated user will be allowed to proxy operations as.
  • ds-auth-may-proxy-as-url -- May be used to provide a list of the LDAP URLs the associated user will be allowed
  Issue:DS-6101 SF#:1690

• 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

New Features

These features were added for version 3.2.0.0 of the Identity Data Store:

• 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.

Known Issues and Workarounds

These were known issues at the time of the release of version 3.2.0.0 of the Identity Data Store:

Resolved Issues

These issues were resolved with version 3.2.0.0 of the Identity Data Store:

• 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

Resolved Issues

These issues were resolved with version 3.1.0.0 of the Identity Data Store:

• 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

Resolved Issues

These issues were resolved with version 3.0.3.0 of the Identity Data Store:

• 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

Resolved Issues

These issues were resolved with version 3.0.2.0 of the Identity Data Store:

• 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

Resolved Issues

These issues were resolved with version 3.0.1.0 of the Identity Data Store:

• 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

New Features

These features were added for version 3.0.0.0 of the Identity Data Store:

• 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.

Known Issues and Workarounds

These were known issues at the time of the release of version 3.0.0.0 of the Identity Data Store:

Resolved Issues

These issues were resolved with version 3.0.0.0 of the Identity Data Store:

• 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

Resolved Issues

These issues were resolved with version 2.2.0.0 of the Identity Data Store:

• 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
