public class UniqueAttributePlugin
extends DirectoryServerPlugin<org.forgerock.opendj.server.config.server.UniqueAttributePluginCfg>
implements org.forgerock.opendj.config.server.ConfigurationChangeListener<org.forgerock.opendj.server.config.server.UniqueAttributePluginCfg>, AlertGenerator

This class implements a Directory Server plugin that can be used to ensure that all values for a given attribute or set of attributes are unique within the server (or optionally, below a specified set of base DNs). It will examine all add, modify, and modify DN operations to determine whether any new conflicts are introduced. If a conflict is detected then the operation will be rejected, unless that operation is being applied through synchronization in which case an alert will be generated to notify administrators of the problem.
