So, how should we handle provisioning a renamed stem to ldap via the
change log ?

Some (maybe most) ldap servers only allow non-leaf objects to be renamed.

When renaming a stem with child stems and groups, we would need to
create the new stem structure, move groups via renaming, and then
delete the old stem structure. I would categorize this as non-trivial.

My suggestion for 2.1 is that we say we do not support renaming
non-empty stems via the change log. A full-sync will create new
objects and delete old ones, rather than renaming or moving.

Thoughts ?
