Referential Integrity Plugin
The Referential Integrity Plugin maintains referential integrity for DN valued attributes.
The values of these attributes can reference entries that have been deleted by a delete operation or renamed by a modify DN operation. The referential integrity plug-in either removes stale references to deleted entries or updates references to renamed entries. The plug-in allows the scope of this referential check to be limited to a set of base DNs if desired. The plug-in also can be configured to perform the referential checking in the background mode specified intervals.
