[krbdev.mit.edu #2577] [Russ Allbery] Bug#250966: /usr/sbin/klogind: Authorization behavior not fully documented

[Public Submitter via RT]

Here's a patch to the klogind and kshd man pages that documents the
authorization behavior when .k5login isn't present and that removes the
last vestiges of references to .rhosts support (which was ripped out of
the code a while back).
