Using ssh-keys for kerberos authentication

[Michael Tautschnig]

Hi!

I'm wondering wether it is (at least theoretically) feasible to use a 
ssh-key to get kerberos tokens!? This is fairly important to me, since 
filesystems such as coda, afs of nfsv4 depend on kerberos-authentication 
to access the filespace.

Patches for ssh exist that pass the token before trying to acces 
.ssh/authorized_keys , but what if one doesn't even have tokens?

Thanks in advance,
Michael
