You can change the configuration to specify additional suffixes or subtrees, or by
specifying to only perform the check under entries that contain a specified object

any other attribute. For more information on the configuration changes you can
make, see "Configuring Attribute Uniqueness Plug-Ins," on page 485.
By default, the Uid Uniqueness plug-in is disabled because it affects the operation
of multi-master replication. For information on using the attribute uniqueness
plug-in in a replicated environment, refer to "Replication and the Attribute
Uniqueness Plug-In," on page 491.
