This chapter covers the status of key issues and limitations for OpenDJ and OpenDJ SDK . For details and information on other issues, see the OpenDJ issue tracker.

OpenDJ 2.6.0 includes important improvements to replication. Replication remains fully compatible with earlier versions. However, some operations that work fine with OpenDJ 2.6.0, such as replicating large groups and replicating high volumes of adds and deletes, can cause issues for earlier versions. Make sure you upgrade all servers to 2.6.0 before allowing clients to take advantage of write operations that could cause trouble for older servers. The following important bugs were fixed in this release. TODO

Release has the following limitations. 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. Global account lockout occurs as soon as the authentication failure times have been replicated. 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. OpenDJ plugin extensions must follow the guidelines set forth in the README file delivered in opendj/example-plugin.zip. When developing your extension, aim to remain loosely coupled with any particular version of OpenDJ. Libraries used must be installed in opendj/lib/extensions/ (or bundle them in your .jar). Keep your configuration separate from the server configuration. Also, unless you are reusing standard schema definitions, keep your schema definitions separate as well. This can affect how your extension works after upgrade. In particular opendj-accountchange-handler-1.0.0 does not work with OpenDJ 2.6.0 after upgrade (OPENDJ-991). See that issue for notes on how make that version of the extension work with OpenDJ 2.6.0.

When deploying for production, make sure that you follow the installation instructions on allowing OpenDJ to use at least 64K (65536) file descriptors, and on tuning the JVM appropriately. The following important issues remained open at the time this release became available. TODO
