You may be getting a bogus error message.

rlogin calls kcmd which calls krb_sendauth.  krb_sendauth sometimes
returns "errno" instead of a Kerberos error code (e.g., lines 206, 214
of the file lib/krb/sendauth.c).  The "errno" value gets passed back
to rlogin, which re-interprets it as a Kerberos error code, so the
problem may have nothing to do with the error code rlogin is giving
you.  (In any case, this is a bug in krb_sendauth.)
