Thanks for the tips; I'll take a look at Nimel schema for a starting point (I'm currently using the one that came with Phamm, and I'm not yet sure how it'll measure up). I also wasn't aware of Apache Directory Studio; I'll give it a whirl. Though I think LDAP Administrator's templates will likely be the primary way of dealing with routine LDAP updates at this point. Something self-cooked for an interface for the users to update their updatable details is likely in the future.
