OK, so in Kerberos your usernames don't have @domain, but in passwd- 
file they do. There are only two possible solutions:

a) Remove @domain from passwd-file (or maybe create with and without  
@domain)

b) Add @domain to kerberos usernames.

I don't know much about Kerberos, so I've no idea what would be the  
proper way to solve this.
