You're using the wrong tools for the job.  pam_krb5 does NOT provide 
passwordless access to remote Kerberized servers; it only verifies 
provided passwords against a KDC by requesting a TGT on the user's 

If you want passwordless, Kerberized SSH, you should look at Simon 
Wilkinson's external-keyx patches to OpenSSH.  There are several 
different Kerberos options for SSH, but I understand this one is
considered the cleanest.  You will have to change both your ssh client
and your ssh server (as Kerberos must be supported on both sides).
