I need to be able to present the memberOf attribute on users on the cache servers.  The man page for slapo-memberof states that it is not compatible with syncrepl.  Because of this the cache servers are using slapo-dynlist to create the memberOf attribute.  The problem is since I am using a dynamic list I can not search using the memberOf attribute only query its value.  I need to be able to search by the memberOf attribute.

What is the recommended way generate the memberOf attribute?  Should I modify the schema for a user and somehow maintain the memberOf attribute on the masters?  I am a bit worried about this since looking at the slapo-memberOf source the memberOf attribute it is flagged as a DSAOperation.
