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?
