They only work if you are using version 1 of the protocol.

- If you're going to login with username and passwd using
kerberos 4 as the authentication method you MUST have a srvtab
for rcmd on the machine you are attempting to log into. If you
want to login via the local passwd mechanism and then attempt to
get an afs token, then you should look into various afs PAM
