UnboundID Synchronization Server Release Notes
|Return to Documentation Index|
Following are notes for version 18.104.22.168 of the UnboundID Synchronization Server. Notes for the following versions of the Synchronization Server are also available in this document:
The following issues have been resolved with this release of the Synchronization Server:
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
Fix an issue where dsconfig could apply changes to multiple servers in a failure situation even though it claimed that no changes were applied. Issue:DS-8677
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
These features were added for version 22.214.171.124 of the Synchronization Server:
IPv6 is now a supported deployment option.
64-bit JDK 7 is now a supported deployment option, but 32-bit JDKs are no longer supported.
These were known issues at the time of the release of version 126.96.36.199 of the Synchronization Server:
These issues were resolved with version 188.8.131.52 of the Synchronization Server:
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 problem where the Synchronization Server could log an error message saying "Could not register a JMX bean", which was due to a race condition in the JMX processing code. Issue:DS-6722
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
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 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, when using a JDBC Sync Source, the Synchronization Server would search for the destination entry using the "identifiableInfo" from the database change record instead of the constructed source entry DN. Issue:DS-6946
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
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
Increase the maximum heap size to 4GB from 1GB for Synchronization Server. Issue:DS-7230
These features were added for version 184.108.40.206 of the Synchronization Server:
The Metrics Engine is a core server product that collects and aggregates key diagnostic, capacity, and usage information from an UnboundID server topology consisting of instrumented Directory Server, Directory Proxy Server, and Synchronization Servers running release 220.127.116.11 and above. Metrics data can be explored and graphed using the included query-metric tool, and the Metrics Engine REST API makes this information available to custom applications and third-party systems. To learn more about the Metrics Engine, please refer to the UnboundID Metrics Engine Administration Guide.
These were known issues at the time of the release of version 18.104.22.168 of the Synchronization Server:
These issues were resolved with version 22.214.171.124 of the Synchronization Server:
Add help text to web console deployment descriptor with JBoss compatibility tips. Issue:DS-6976 SF#:1749
These features were added for version 126.96.36.199 of the Synchronization Server:
The Synchronization Server now supports a generic Sync Source API in the Server SDK, which allows the Synchronization Server to detect changes from different types of endpoints such as the Force.com platform, Google Apps, a flat file, or virtually any other kind of data source. For more information and an example, please refer to the UnboundID Server SDK documentation.
The Synchronization Server now supports a SCIM Sync Destination, which enables the synchronization of user and group entries to the cloud via the SCIM protocol.
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.
These were known issues at the time of the release of version 188.8.131.52 of the Synchronization Server:
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
In failover scenarios, the SCIM Sync Destination may report that HTTP status code 500 was received and was the cause of a failover, even if no response was actually received from the server at all. Currently the SCIM-SDK does not have a mechanism to report local errors such as this. Issue:SCIM-287
These issues were resolved with version 184.108.40.206 of the Synchronization Server:
Fix an issue where multiple server configuration changes would fail if any of the servers were configured with an LDAPS (SSL) connection handler. Issue:DS-5100
Update the Synchronization Server to not look at the deletedEntryAttrs on changelog entries when determining whether to ignore a change based on the modifiersName attribute. Issue:DS-4171
Update the collect-support-data tool to include the equivalent of jstack output for IBM VMs on non-AIX platforms. Issue:MON-5027
Update the Synchronization Server to utilize the destination schema when synchronizing with an LDAP directory. This ensures that the sync engine will treat DN attributes and other types correctly when performing its diff. Issue:DS-3447
Update the Password Sync Agent for Active Directory to support 64-bit Windows operating systems. Separate binaries for x64 and x86 are now provided.
Fix a Validator error which could occur in the SyncPipe if the modification set to apply was empty (which can only happen in notification mode) and there was a failure at the destination endpoint. Issue:DS-5320
Update the Sync Server to use the original source DN when correlating entries at the destination for modify operations. Previously, if the entry had been renamed at the source immediately after the modify, the Sync Server would use the new entry DN to try and locate the destination entry. Issue:DS-5403 SF#:00001603
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
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 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
Change informational message when changelog indexing is not used on a sync pipe to be a debug trace instead. Issue:DS-5604
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
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 peer installs were updating servers of the wrong type from the master server's ADS. Issue:DS-5552
Change prepare-external-server to allow not supplying a trust store password in non-interactive mode, which will force the script to only trust the servers that are already present. Issue:DS-5872
Add additional checking to prepare-endpoint-server to ensure that the Sync User on a DSEE server has the appropriate attributes to prevent usage limitations. Issue:DS-5367 SF#:1598
Fix an unqualified static method invocation in the example ComplexJDBCSyncDestination Groovy script that is shipped with the Synchronization Server. Issue:DS-5299
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
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
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
Update the Synchronization Server to use location-based failover for LDAP and SCIM endpoints. It will prefer to fail over to external servers which are in the same location as itself whenever possible, followed by servers in the preferred failover locations as defined in the configuration. Issues:DS-5016,DS-5412,DS-5413
Fix an issue where the Generic Sync Source and Destination extensions did not properly handle the ABORT_OPERATION result when it was specified in an EndpointException thrown by the extension. Issue:DS-5270
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
Update the create-sync-pipe-config tool so that it will fail immediately and display an error message if there is a problem creating the configuration objects in the Synchronization Server. Issues:DS-4208,DS-5019
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
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
Add changelog-reset detection to the Synchronization Server so that it will issue a purge alert if it detects that the source changelog has been deleted or reset. Issue:DS-5280
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
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
Improve detection of active sync servers in a failover group to ensure that low priority master servers will stop syncing if more than one is ever made master at the same time due to network partition or other system wide failures. Issue:DS-6395 SF#:1710
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
Added support for two-legged OAuth 2 authentication method for SCIM external servers. Both the "Bearer" and "OAuth" token types are supported. Issue:SCIM-302
Add the ability to constrain a Sync Log Publisher to one or more specific sync pipes. This allows you to create a sync logger that will show only the output for the sync pipe(s) you are interested in. Issue:DS-5344
Updated the server to support hosting of standard web applications using the HTTP Connection Handler. Issue:MON-754
Fix a bug that could result in a standby Sync Server starting a Sync Pipe when it comes online. Issue:DS-6486 SF#:1727
Add lock down mode detection for the sync server that will force the sync engine to stop when entering lock down and start up again when leaving lock down mode. Issue:DS-6573 SF#:1734
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
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 resync tool did not adequately report the lack of endpoint preparation when the sync pipe was set up against the Directory Proxy Server. Issue:DS-3426
Fix an issue where a Sync Pipe would stop updating its monitor statistics for the source endpoint if it became severely backlogged and was waiting for some in-flight operations to finish before bringing in new changes. Issue:DS-6666 SF#:1740
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
Fix the prepare-endpoint-server tool to handle the case where ACI values for the Sync User already exist on the synchronization base DN. Issue:DS-6552
Fix a bug in the SCIM Sync Destination where it might try to connect to the SCIM endpoint when the sync pipe is stopped, and also might log a NullPointerException. Issue:DS-6728
Fix an inconsistency in the Sync Pipe statistics where the 'ops-completed-failed-at-resource' stat could be incremented when it shouldn't be. Issue:DS-6464
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 problem where the Synchronization Server could log an error message saying "Could not register a JMX bean", which was due to a race condition in the JMX processing code. Issue:DS-6722
These features were added for version 220.127.116.11 of the Synchronization Server:
AIX is now a supported deployment operating system.
These were known issues at the time of the release of version 18.104.22.168 of the Synchronization Server:
These issues were resolved with version 22.214.171.124 of the Synchronization Server:
Fix an issue where, for an UnboundID Sync Source, the Sync Server could lose some changes during fail over to another sync server if the persistent state had not yet been saved for the first time. This is unlikely to affect a production environment. Issue:3400
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
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
Add a new stat to the Sync Pipe Monitor to expose the current throughput rate, in operations processed per second. This stat is available using the status command on the Synchronization Server as well. Issue:3556
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
Fixed an issue with the JDBC Sync Source where after a failure it could potentially re-fetch changes that had already been processed. Issue:3276
Fix an issue in the Synchronization Server where alerts were not always generated when an endpoint server transitioned from unavailable to back to available (i.e. came back online). Limit changelog purge alerts from the Synchronization Server to once every ten seconds rather than once per poll of the changelog, and add the name of the Sync Pipe to the alert. Issue:3626
Fix an issue where the Synchronization Server memory usage could spike when a Directory Server goes down behind a Proxy. Issue:3628
Improve error message when extension class can not be loaded. Issue:3245
Fix an issue in the Synchronization Server where JDBC Sync Source and Destination extensions would not correctly initialize their ArgumentParser when running within the resync command. Issue:DS-4169
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
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:
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
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
Change the default behavior of the Synchronization Server to not lock entries across all Sync Pipes when processing changes.
The Sync Server has a specialized mutex that ensures that changes to the same entry are processed serially. The primary reason for this mutex is to ensure that the server can safely process changes in parallel to achieve high throughput. However, we also use this mutex to ensure that two Sync Pipes don't process the same entry at the same time for deployments that synchronize changes bi-directionally. A consequence of this locking is that if one Sync Pipe is failing (because the destination is unavailable) then it retains the lock on an entry, and when other Sync Pipes try to process changes to that entry they will block that change and all changes that follow it while they wait on the lock.
This change turns off using a shared mutex by default, but adds a new advanced configuration option on the Sync Pipe, shared-mutex-name, that specifies the name of a mutex that is shared by other Sync Pipes. This gives greater control over the locking so that two Sync Pipes that share end points can ensure that two changes to the same logical user are not processed concurrently, while not impacting other Sync Pipes.
See the shared-mutex-name property for more information.
This property is subject to change in a future release. Issue:DS-4202 SF#:1527
Enhance sync setup, when adding to an existing topology with JDBC nodes configured, to check if needed library files are in place before warning that manual copying may be needed. Issue:DS-3194 SF#:1471
Update dsconfig to remove a redundant prompt when a user chose to "Change the value" of an existing property. Issue:DS-2140
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
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 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
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
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 an issue in which setting the changelog-max-before-after-values property to unlimited causes sync server to indicate all attributes as exceeeding the maximum value. Issue:DS-4549
Update the Periodic Stats Logger to include additional information in the "SyncPipeInfo" category. The new output columns are "Source Is Connected", "Source Connected Server", "Destination Is Connected", "Destination Connected Server", "Source Unretrieved Changes", "Completed Aborted by Plugin", "Completed Failed in Plugin", and "Synchronized Out of Date Changes". Issue:DS-3575
Fix an issue where the Synchronization Server would report null pointer exceptions in the error log if all external servers for a given endpoint became unavailable. Issue:DS-4415
Update the SyncPipe with the ability to specify a "filter-changes-by-user", which allows it to perform access control filtering on the source data before synchronizing. Modified the sync engine to send alerts only if the unavailable source attributes (due to ACI filtering or exceeding the max values) were ones that the Sync Pipe was interested in. Added new stats to track how many sync operations have been filtered by ACIs and how many have exceeded the max before/after values. Updated the create-sync-pipe-config tool to support the new ACI filtering features and enable them on the Sync Pipe if desired. Updated the prepare-endpoint-server tool to support the new ACI filtering features and enable them on the directory server changelog if desired. Issue:DS-4564
Add a new listAllEntries() method to the JDBCSyncSourceAPI which allows resync from a file to include the entryType argument. Note that this breaks compatibility with the previous listAllEntries() which did not include the entryType parameter. Existing code will continue to compile, but the old method will no longer be used by the server and you will be forced to implement the new version when resyncing a database using a source input file. Issue:DS-3542
Update the create-sync-pipe-config tool to check that the source endpoint has the minimum required version before configuring ACI filtering for notifications. Issue:DS-4564
Fix an issue with database synchronization where a null pointer exception could be thrown if the username or password were left blank on the JDBCExternalServer configuration.
Fix an issue where old configuration data may get left in a topology of Sync or Proxy servers after a server is uninstalled or removed from the topology. Issue:DS-4712
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 Synchronization Server, so that within a polling interval, multiple batches of changes can be retrieved from the source server. This increases throughput without having to specify a small polling interval. Issue:DS-4859
Fix an issue with the "realtime-sync" tool where it would not print specific error data to the screen if a problem occurred while stopping a sync pipe. Issue:DS-4521
Add a new configuration property to the SyncPipe called "include-changes-for-unchanged-attributes". This can be used to override the default behavior of only applying the minimum set of changes to bring the destination entry into sync and instead cause Sync to include modifications for attributes that were changed to the same value they already have. Issue:DS-4963
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
Update the Synchronization Server to take advantage of changelog indexing on the source endpoint if it is available. This can provide significant performance gains when synchronizing from UnboundID servers, especially if the data is entry-balanced. Issue:DS-4955
Improve the dsframework tool to support multi-valued server propreties. Issue:DS-5040
Fix an issue in the Synchronization Server where a sync pipe in notification mode would not take advantage of virtual attribute information in changelog entries. Issues:DS-5069,DS-5071
These features were added for version 126.96.36.199 of the Synchronization Server:
Update the Synchronization Server to support arbitrary Sync Destination end points via a Server SDK extension. Sync Destination implementations can be written in Java or Groovy.
Add a new "notification" mode to the Synchronization Server. When a Sync Pipe is configured in this mode, it skips fetching the full entry from the source and instead immediately notifies the destination with the contents of the change. The details of the change are completely derived from the source changelog entry. This enables a destination to go through the same sequence of changes as the source.
The Synchronization Server can now be monitored over SNMP.
These were known issues at the time of the release of version 188.8.131.52 of the Synchronization Server:
These issues were resolved with version 184.108.40.206 of the Synchronization Server:
Add new global configuration attribute that allows specifying a SMTP timeout to use for all configured SMTP servers. Issue:2283
Exposed the SyncOperation class where appropriate in the JDBC Sync Source and Destination interfaces for the Server SDK. This is consistent with the other types of sync plugins that have access to the SyncOperation. Issue:2934
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
Added support for Java-based JDBC Sync Source and Destination extensions. Previously these were only available in Groovy. Issue:3003
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
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.
Fix an issue where status output failed to complete due to stale JDBC connection. Issue:3170
Updated the create-sync-pipe-config tool to support setting up a Sync Pipe in notification mode. It now also supports using pre-existing Sync Sources discovered from the existing configuration. Issue:3024
Changed the --sourceDNsFile argument for the Resync command to be --sourceInputFile. It now supports DNs for resync from LDAP as well as a user-defined format for resync from a database. Issue:2734
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
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
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
Added support for SNMP monitoring to the Synchronization Server via the SNMP Subagent Plugin. A Sync Pipe MIB has been supplied. Issue:3229
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
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
These issues were resolved with version 220.127.116.11 of the Synchronization Server:
Fix an issue in the Synchronization Server where "the next batch of changes" could not be retrieved. This occurred when synchronizing through a proxy server after a backend directory server had been restarted. Issue:3205 SF#:1472
Add an option to collect-support-data for collecting data from expensive processes. These expensive operations will not be executed by default. Issue:3176
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
Add a configurable sync backlog threshold to the Sync Server so that alerts will be generated when a sync pipe becomes severely backlogged with unprocessed changes. Another alert will be generated when the backlog goes back below the configured threshold. Add alerting when the Sync Server detects that changes have been missed because they were purged from the source changelog before the sync pipe had a chance to process them. Issue:3199
Add a configuration option to allow the Synchronization Server to synchronize delete and moddn operations even if they are out-of-date with the source server. Issues:3181,3230 SF#:1460,1461
Add a configuration option (allow-destination-renames) to the Sync Class to control whether a rename of an entry (e.g. moddn in LDAP) should be allowed at the destination in the process of synchronizing a modify operation. Issue:3225 SF#:1475
Fix an issue where the sync server could attempt to process source changes it had already seen when an UnboundID or Sun DS sync source failed over from one source server to another. This would happen when the only changes being made on the source servers were ones that did not need to be synchronized (for example if bi-directional sync was configured and the changes in question had been made by the sync server). Issue:3100
Fix a bug that could cause resync from an UnboundID sync source to fail with a null pointer exception. Issue:3275
Fix an issue where in rare circumstances if all endpoint servers were unavailable, the Synchronization Server might not reconnect to them when they become available. Issue:3278
These issues were resolved with version 18.104.22.168 of the Synchronization Server:
Modify the update tool to fix an issue where in some cases the tool would fail to migrate an older configuration, displaying errors related to duplicate LDIF change records. Issues:2942,2962,2967
Add support for Java-based JDBC Sync Source and Destination extensions. Previously these were only available in Groovy. Issue:3003
Fix an issue in the Synchronization Server where the attribute-synchronization-mode 'all-attributes' would handle deleted attributes incorrectly. Issue:3026
Fix a regression with the stop-sync-server command where the port argument was ignored. Issue:2925
The create-sync-pipe-config tool now correctly handles connecting to the SSL port of an LDAP server when specified as part of an endpoint. Issue:2952
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
Expose destination-create-only-attr as a Sync Class property to allow certain attributes (such as objectclass) to only be set when an entry is created and not when it is modified. Issue:2947
The command-line tools now use the full terminal width for output on Windows platforms. Issue:1019
Fix a regression where the Synchronization Server could not synchronize with Sun DSEE 5.2p4 instances because this version of DSEE did not allow the filter "(&)" to match any entry contrary to the LDAP specification. Issue:3069 SF#:00001449
The setup tool has been modified to correct an issue in which the presence of the --rootUserDN option, when specified with any of the "Set Up From Peer/Master Server Options", would cause setup to exit with an error. Issue:3084
Increase the recommended default for LDAP changelog retention to be 2 days instead of 2 hours to match real world deployment expectations. Issue:3105
Fix an issue where the Groovy "assert" statement was not handled correctly in Server SDK extensions used to synchronize with a database. Issue:3137
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.
Address an issue where Server SDK extensions running within a command line tool could cause the process to run out of memory if they logged a high volume of error log messages. Issue:3173
These issues were resolved with version 22.214.171.124 of the Synchronization Server:
Change collect-support-data tool to prompt for missing LDAP connection arguments if needed. Issue:2461
Fix an issue where the Synchronization Server could occasionally report a severe initialization error on startup leaving the Sync Pipes disabled. Issue:2835
The script file for stopping the server on non-Windows operating systems have been modified so that when it is invoked with no arguments, the server is killed using the operating system's kill command, ensuring that the server will have stopped when the script returns. Issue:2821
The remove-defunct-server tool has been enhanced to allow the user to choose to continue processing of topology servers even if one of the servers is down. In non-interactive mode this is accomplished using the --continueOnError option. Issue:2856
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
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.
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
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.
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
Expose the SyncOperation class where appropriate in the JDBC Sync Source and Destination interfaces for the Server SDK. This is consistent with the other types of sync plugins that have access to the SyncOperation. Issue:2934
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
These features were added for version 126.96.36.199 of the Synchronization Server:
Database Synchronization - Support for high-scale, highly-available data synchronization from one endpoint consisting of one of our supported Directory Servers with the other endpoint consisting of a relational database management system (RDBMS). UnboundID officially supports synchronization with Oracle Database 10g and 11g as well as Microsoft SQL Server 2005 and 2008. The architecture, however, does not make any assumptions about the type of database or schema being managed; any database with a Type 4 JDBC driver can be used.
Server SDK - Server-side SDK for extending the functionality of the core server.
Synchronization Through Proxy - Support for Synchronizing to or from an load-balanced or entry-balanced proxy server deployment.
Virtualization Support - Achieved "VMware Ready Status" for all of our server products, which we now support deploying in VMware environments.
These were known issues at the time of the release of version 188.8.131.52 of the Synchronization Server:
These issues were resolved with version 184.108.40.206 of the Synchronization Server:
Update the Synchronization Server installer so that all servers within a topology will use the same IntraSync-User password. Issue:1970
Add a background retry mechanism to the Synchronization Server so that failed operations can be optionally retried after a specified delay. Issue:2040
Add the ability to specify separate destination correlation rules for deleted entries, so that deletes can use a more relaxed set of rules if need be. This can be useful in scenarios where applications delete and then re-add the same entries (with different attributes), for example. Issue:2072
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 potential memory leak in the Synchronization Server which could occur during Sync Source failover if there were a large number of pending changes in the queue at the time of failover. Issue:2169
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
Added a safeguard to the LDAP Sync Source so that it will not wait forever for responses to asynchronous changelog searches (particularly with DSEE).
Update the stop script so that the "restart" option will correctly restart the server after a successful shutdown Issue:2329 SF#:1362
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
Reduce the maximum timeout value from 10 minutes to 5 minutes for Synchronization Server changelog searches against DSEE, and add some extra checks for connection health. The configured response timeout on the Sync Source is still preferred, but if none is set, then this value will be used as a ceiling. Issue:2383
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
Modify the update tool to disallow the update tool from being used from a package in which setup has been run. Issue:2464
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 resync tool to fail immediately if no destination servers are available. Issue:1181
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
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
Remove forced min utilization configuration setting for replication and LDAP change logs. These settings had led to excessive database growth in some circumstance. Issue:2294 SF#:1352
Improve the output of the ldapsearch tool to mention that a password has expired when the bind occurs. Issue:1981 SF#:1227
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
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 Synchronization Server to connect immediately to the destination server of a Sync Pipe rather than waiting for a change to come through. This enables the server to show in its status that the destination server is connected. Issues:2005,2389,2547
Update the Synchronization Server to send an admin alert when a Sync Pipe fails to start up (because of a configuration error or scripting error) and continue starting other pipes. A new alert type has been added for this condition, called sync-pipe-initialization-error. In the case of such an error, a Sync Pipe may be restarted with the server online via the realtime-sync tool. Issue:2547
Update the realtime-sync tool to read arguments from the config/tools.properties file if present. Issue:2513
Improved status command output to better inform the user of how the local server status was determined, based on the arguments provided. Issue:2487
Update cli documentation to include new commands for updating and reverting a server installation. Issue:2573 SF#:1390
Tools using a scope argument are now correctly documented in the CLI documentation. Issue:2594
Added a new configuration property to the Sync Class which allows you to control as part of a sync operation whether all attributes should be brought into sync on the destination or only those that were affected by the originally modified attributes at the source. The property is called 'attribute-synchronization-mode'.
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
Add extension points for the Synchronization Server. This includes Sync Pipe Plugins, LDAP Sync Source Plugins, and LDAP Sync Destination Plugin. Issue:2410
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
Add an option to display the status for just a specific Sync Pipe in the status command output. This makes the output a lot easier to read if there are multiple Sync Pipes configured. Issue:2606
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
The file-based loggers now optionally support millisecond level precision. Issue:2603
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
Improve output when JVM errors occur in scripts used to set up environment for command line tools. Issue:2172
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
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
Address an issue with the web console where it would not allow read-only configuration properties to be set when an object was initially created. Issue:2730
These issues were resolved with version 220.127.116.11 of the Synchronization Server:
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
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.
Modify the prepare-external-server tool so that it will look for trust store and password files in the default locations when using SSL or StartTLS and the locations of those files are not explicitly provided.
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.
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
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.
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 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.
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.
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 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 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 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.
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
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 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.
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 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
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
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
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
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
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 prevent multiple loggers from being configured with the same target log file. Issue:1676
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.
Rename the upgrade tool to be "update", and rename the revert-upgrade tool to be "revert-update".
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 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 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 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
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
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
