The Unique Attribute Plugin enforces constraints on the value of an attribute within a portion of the directory.
The values for each attribute must be unique within each base DN specified in the plugin's base-dn property or within all of the server's public naming contexts if no base DNs were specified.
The Unique Attribute Plugin component inherits from the Plugin
A description of each property follows.
Basic Properties: | Advanced Properties: |
