OpenDJ Fixes, Limitations, and Known Issues

OpenDJ issues are tracked at This chapter covers the status of key issues at release 2.4.5.

Fixes since last release

The following issues were fixed since release 2.4.4.

  • OPENDJ-349: manage-account returns Seconds Until Idle Account Lockout: 0 (zero) if the last log on date is more than 24 days before the idle lock out interval.
  • OPENDJ-387: dsreplication initialize-all reports negative percentage of completion
  • OPENDJ-400: ControlPanel issue with values containing \n (such as sunxmlkeyvalue)
  • OPENDJ-401: Replication fails with Java 7.
  • OPENDJ-410: Frequent corruption in ds-sync-hist ordering index.
  • OPENDJ-413: verify-index with "-c" option doesn't work for certain indexes
  • OPENDJ-420: Rare SSLExceptions while handling LDAPS connections and big LDAP searches


Release 2.4.5 has the following limitations, none of which are new since 2.4.0.

  • OpenDJ directory server provides full LDAP v3 support, except for alias dereferencing, and limited support for LDAPv2.
  • When you configure account lockout as part of password policy, OpenDJ locks an account after the specified number of consecutive authentication failures. Account lockout is not transactional across a replication topology, however.
  • OpenDJ is not fully integrated with Microsoft Windows, yet OpenDJ directory server can be run as a service, and thus displayed in the Windows Services Control Panel.
  • OpenDJ replication is designed to permit an unlimited number of replication servers in your topology. Project testing has, however, focused only on topologies of up to eight replication servers.

Known issues

The following issues remained open at the time release 2.4.5 became available.

  • OPENDJ-68: On T2000 systems, hardware SSL crypto acceleration is slower than software. To work around this issue: 1) add more request handlers to LDAP (for TLS) and LDAPS (for SSL) connection handlers; 2) disable hardware acceleration for server's JVM by removing the SunPKCS11 security provider from jre/lib/security/
  • OPENDJ-88: Online backup of cn=config does not work
  • OPENDJ-98: Searches on cn=monitor take a long time
  • OPENDJ-109: jar files that are put into $OPENDJ_ROOT/lib/extensions are not visible in classpath
  • OPENDJ-136: On Windows, upgrade fails with NPE during Verify phase
  • OPENDJ-137: Registering OpenDJ as a Windows Service is not recommended.
  • OPENDJ-145: Upgrade hangs if the OpenDJ is running and properties files is used.
  • OPENDJ-169: Modifying ObjectClass in Control-Panel requires restart
  • OPENDJ-208: Schema changes over LDAP allow duplicate attributes depending if the attribute is defined as single-valued or not
  • OPENDJ-249: dsreplication disable --disableAll error removing contents of "cn=admin data"
  • OPENDJ-270: dsreplication disable takes a long time
  • OPENDJ-301: Unauthenticated rebuild indexes only shuts down the backend
  • OPENDJ-312: Control Panel Restore Verify Backup fails with a NPE if no base DN
  • OPENDJ-314: OpenDJ as Windows Service can not be stopped using control-panel
  • OPENDJ-315: OpenDJ not restart when enable as automatic windows service after reboot
  • OPENDJ-318: QuickSetup upgrade does not start server if upgrade completed checked
  • OPENDJ-320: log-file-permissions ignores group permissions
  • OPENDJ-322: Binary encoding option causing problems in replace operations
  • OPENDJ-323: If you attempt to rebuild an index that doesn't exist while OpenDJ is running then the backend is left offline
  • OPENDJ-332: In Replication server Replication Server 9989 15435: replication servers and have the same ServerId : 12360
  • OPENDJ-334: PermissiveModifyRequestControl not replicated which may cause divergence
  • OPENDJ-340: dsreplication disable takes --bindDN, but --adminPassword instead of --bindPassword
  • OPENDJ-344: Upgrade fails when there's an extension with additional JAR dependency.
  • OPENDJ-347: Misleading error when running setup
  • OPENDJ-365: Potential deadlock in JE backend while performing a mix of update operations
  • OPENDJ-390: ConcurrentModificationException during backup all
  • OPENDJ-398: Misleading replication messages: "Replication server XXXX was attempting to connect to replication server YYYY but has disconnected in handshake phase"
  • OPENDJ-399: DirectoryException thrown processing of virtual static groups during backend initialization
  • OPENDJ-405: Upgrade fails in many cases when configuration modified in the server to upgrade.
  • OPENDJ-412: Blocked persistent searches may block all worker threads

Furthermore when deploying for production, make sure that you follow the installation instructions on allowing OpenDJ to use at least 64K (65536) file descriptors, tuning the JVM appropriately, and increasing database cache size from the default of 10%.
