[Fedora-directory-users] new user entry starts with uid=

Hi, 
 
Fedora-ds 1.0.4.
 
New User entry in the directory will have a RDN starting with uid= .  I would like to
change that to cn=
Know that in de advanced properties one can change the Naming Attribute, but I want it to
be cn= on creation of  a new entry.  Where can I change those default setting(s).
 
Thnx
