[Samba] displayName vs. cn

With 3.0.14 it was different, all our users got full names. I didn't try
3.0.20, but can do if necessary.

Because of this change I realized how poorly our displayNames are maintained
(only 5 of 150 users), in fact since 3.0.20a most users doesn't have a full
name any longer in the user list.
In user details (and for instance in Windows login information after
Ctrl+Alt+Del) they still have.
Both entries in Usrmgr claim to have the full name, but they differ.
