[Samba] samba4 alpha 21 kerberos problems

[em.tie at gmx.de]

Dear Samba Team,

I have just installed Samba4 from git on Ubuntu 12.04 according to http://wiki.samba.org/index.php/Samba4/HOWTO but I'm stuck at testing Kerberos. kinit always returns:

kinit: Preauthentication failed while getting initial credentials

what can I do?
