In a nutshell, it's a proxy service (yes, this is for work), and users
should not be able to share logins with their friends.  The user
accounts themselves are maintained in a chrooted environment.  There's a
cron job that checks the DB every 5 minutes, adds new accounts to
/var/chroot/etc/passwd and friends, and creates homedirs as needed.
Password authentication is provided by pam_mysql currently, but the
whole setup is being re-thought.

Right now, we're limiting it to only one login per machine, but there
will be more (mostly virtual, possibly some physical) machines added to
the mix shortly.  The MySQL DB is currently replicated to each machine,
and authentication happens locally (that whole "single point of failure"
thing being undesirable).  I'm currently trying to figure out the best
way to approach this, be it LDAP, NIS+, Hesiod, NSS-MySQL, or whatever.
