Hello, all. A bunch of tired googling hasn't quite given us what we need so I thought I'd ask the list. Is there a way to store email distribution lists in DS?

We are in the midst of integrating DS and Zimbra. We elected to not use DS as the LDAP store for Zimbra despite the excellent community contributions to make it possible. We did this in case a future upgrade to Zimbra makes major schema changes which could potentially break our setup.

Instead, we opted to use DS as an external LDAP authentication source and GAL for Zimbra. This is working very nicely but we've hit a bit of a wall with distribution lists. We don't want to store them in Zimbra because they do not show up in our exclusively external GAL but we do not know how to store them in DS. The groupofmailenhanceduniquenames looks interesting but is apparently reserved for future use. mailgroup looks useful but we are not sure how to use it. It looks like an object class which is added to a user object and not a group object. Can anyone point us in the right direction? Thanks - John
