Greetings.
Finally I've set up kerberos properly but an issue still remains. 
Is it possible to delete the passwd entry from all the systems that belong to
the realm ? Right now, I'm obligated to have a passwd entry for the user in each
system. Maybe do I need another software to help me with that ?

Best regards.
