Arguments
When enabled, the postoperation Referential Integrity Plug-in
performs integrity updates on the member, uniquemember,
owner, and seeAlso attributes immediately after a delete or
rename operation. You can reconfigure the plug-in to perform
integrity checks on all other attributes.
Configurable arguments are as follows:
1. Check for referential integrity.
-1 = no check for referential integrity
0 = check for referential integrity is performed immediately
positive integer = request for referential integrity is
queued and processed at a later stage. This positive integer
serves as a wake-up call for the thread to process the request, at
intervals corresponding to the integer specified.
2. Log file for storing the change; for example,
/opt/redhat-ds/servers/logs/referint
3. All the additional attribute names you want to be checked for
referential integrity.

Information
You should enable the Referential Integrity Plug-in on only one
supplier in a multi-master replication environment to avoid conflict
resolution loops. When enabling the plug-in on chained servers,
you must be sure to analyze your performance resource and time
needs as well as your integrity needs. Integrity checks can be
time-consuming and draining on memory/CPU.

Directory Server Administrator’s Guide.
