389 Directory Server is an LDAPv3 compliant server. The base package includes
the LDAP server and command line utilities for server administration.

Fixed bugs:

* When multiple replica update vector (RUV) updates were skipped in fractional replication, RUV was not updated at the end of the session. The next session then restarted evaluating the same skipped updates. To fix the problem, a system subentry has been added, which is occasionally updated even when no applicable changes can be replicated at the time of the update. This prevents the unnecessary replays.
* Previously, Directory Server did not correctly handle requesting searches for simple paged results asynchronously in a persistent connection. If one of the requests was abandoned, the ns-slapd service sometimes terminated unexpectedly. A patch has been applied to fix the problem, and ns-slapd no longer crashes in the described situation.
* Directory Server previously did not properly handle freeing search result objects. A delay occurred between freeing an object and providing the freed information to the paged results handle. If the handle was released because of a timeout during the delay, a double free error occurred, which caused the ns-slapd service to terminate unexpectedly. This update eliminates the mentioned delay, thus preventing the double free error. As a result, ns-slapd no longer crashes in this situation.
