Ah, I think you are mixing up Unix permissions and windows permissions.
You will only get 'Administrator' to show up with getent if you give the
Administrator user a uidNumber and use the 'ad' backend. As you are
mapping 'Administrator' to root it will get the UID of '0' which is also
the UID of 'root'. From windows you will set the permissions of
'Administrator' , but on the unix side using getfacl it will show as 'root'
