A bit more detail:

Normal users can no longer login, they receive:
No supported authentication methods left to try!

I can still login with root and toor.  I've tried everything I know of, short
of rebooting it.  If you guys have any insight, it's greatly appreciated, as
I'm at a total loss.

With the normal user that is currently logged in (before this occured), here
are some examples of the odd behavior:

captkirk at hybrid:~$ /bin/ls
-bash: /bin/ls: Permission denied

root at hybrid:/etc/rc.d# /bin/ls -al /bin/ls
-r-xr-xr-x  1 root  wheel  22784 Nov  4 19:24 /bin/ls

root at hybrid:/etc/rc.d# finger captkirk; grep captkirk /etc/master.passwd
finger: captkirk: no such user
captkirk:<password hash>:1005:1005:default:0:0:Matt
Rechkemmer:/home/captkirk:/bin/tcsh

When users get the "No supported authentication methods" error, I do see valid
authentications in /var/log/auth.log.  So this behavior makes no sense, to me
anyways.

Any ideas?
