Hi LPH & David,

Im also interested in using kerberos authentication and tried your
hints. Im using Ubuntu 14.04.3 Server on this machine.

@LPH: krb5-ssh doesnt exist in Ubuntu:

# apt-get install krb5-ssh
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package krb5-ssh

But maybe you mean libpam-krb5?

I didnt found "kerberos" in the selection-list. But with "libpam-krb5"
installed it is shown.

@David: Did you enable Kerberos authentication in /etc/ssh/sshd_config?
I see to select:

# Kerberos options
#KerberosAuthentication no
#KerberosGetAFSToken no
#KerberosOrLocalPasswd yes
#KerberosTicketCleanup yes

What should I enable from these?

$ LANG=POSIX id oliver
uid=1000(oliver) gid=1000(oliver)

Where should I see shell and homedir here?
