so that it is the DSA itself, or rather an embedded client, that maintains
that type of consistency; that project hung on the lack of some design
issues and on the lack of atomicity in multiple write operations that
characterized slapd at that time. I guess LDAP transactions under
development for HEAD should solve those isues. You may try to implement

Thank you for the reply.
I see what you're saying... I found some past discussions on this topic:
I'm just trying to support one standard mechanism, but it appears that
there is none...
Active Directory does support 'dynamic' memberOf attribute which made me
assume that it's some kind of a standard (I said that I'm very new to LDAP).
It looks like I'll have to implement two JAAS Login Modules for LDAP:
one with and the other without dynamic memberOf support.
