This existed before, so I'm not asking for a change, but are these standard LDAP attributes? Or are they attributes we expect when using this strategy?

Both, really. member and uniqueMember are attributes of the groupOfNames and groupOfUniqueNames object classes (and Active Directory's group category), and memberUid is for the posixGroup object class.

Hardcoding these here (and elsewhere) is a smell. Addressing that smell is a fairly large engineering undertaking that isn't possible right now. I have some ideas I'd like to run by you, though, for the future.
