Sounds good. Pretty sure that AD uses UUID references everywhere too, for 
similar reasons.

I've suggested a few times in the past that LDAP needs a 
UUIDAndProvisionalName syntax. The UUID would always be present; the DN may be 
present but may or may not be correct/up to date. (Of course, it may seem 
senseless to carry a DN around if it isn't always going to be correct, but the 
point is to reserve a space to put it for when you do know the correct name, 
that's all.)
