We use our own version of crypt() which is different from the one is libc.
This thwarts on-line (and offline) attempts at "guessing" someones
password.

Login checks for dumb passwords and forces you to change them.  Dumb passwords
are your login name forward, backward, capital, lower.  Other nice things
to add someday would be words in the dictionary.  Someday.  It's coming,
it's coming.... So is Christmas!

This stuff uses hashed password file: /etc/hpasswd_nm  It also uses
the account status field in the descriptor field of the password entry.
(As well as the number of tty's logged in at the current moment.)
