Hi
That could be it. The OP's ldif for adding the uidNumber is fine, but
the schema wants none of it. The schema that ships with Samba4 works
fine _if that is the first DC in the domain_. As Rowland says, this is
likely caused by the Samba4 DC being joined to an existing domain based
on 2003 or before. The only difference between our (working) ldif is
that we are adding to CN=Users, not an OU.
