I take it that you only use the PDC for authentication and don't let the users login. It has been sometime since I setup and used a linux client with a PDC, but I don't actually remember having all those passwd & script lines in the client smb.conf. Do the users exist as unix users on both machines ? Rowland

Than the users can login on a joined ubuntu computer in the classroom. It does not matter which one. The long number (as their username) comes from a smartcard). I have this setup in many schools, and working ok. But on this setup, with the long numbers as usernames, i have problems. As I was debugging, i tried to su the user on a client machine, and got another user instead: root at blank005:~# su 59031614949 98121524292 at blank005:/root$ I never seen this . Is it a problem with long usernames and winbind?
