Server Plug-in Issues

iPlanet Directory Server 5.1 provides the UID Uniqueness plug-in. By default the plug-in is not activated. To ensure attribute uniqueness for specific attributes, create a new instance of the Attribute Uniqueness plug-in for each attribute. For more information on the Attribute Uniqueness plug-in, refer to the iPlanet Directory Server 5.1 Administrator's Guide.

The Referential Integrity plug-in is now off by default. The Referential Integrity plug-in should only be enabled on one master replica in a multi-master replication environment to avoid conflict resolution loops. Before enabling the Referential Integrity plug-in on servers issuing chaining requests, analyze your performance resource, time, and integrity needs. Integrity checks can consume significant memory and CPU resources.
