Sometimes coincidence is spooky. I just had an exchange of emails with Tom
Zeller about this issue earlier today, and it was the first time I had
thought about it in a long time.

We could revive that draft, which is still on the shelf, though a little
dusty. There are counter-arguments having to do with the need to support both
eduIsMemberOf and isMemberOf, and distinguish them with different OIDs. I'd
like to see a little discussion on the Grouper and MACE-Dir mailing lists
before going ahead.

One perhaps naive starter question from me: Since the isMemberOf attribute
has a unique OID,, does it really matter what name
you associate with it in your LDAP schema? I believe that you could give it a
custom name in your directory, and as long as the OID is as above, nothing
bad happens. If you are expressing group memberships in federated contexts,
then there is a SAML profile for how to do this. Again, no impact on your
internal directory schema. Am I missing something?
