I know its what's being asked here.
but a tip to newbie sysadmins.
If you want to keep those pesky users off your system,
for example if you have a BIG PROBLEM you need to solve, or you
are scheduling a shutdown, look at the man pages for nologin.
If the file /etc/nologin exists the system won't allow fresh non-root
logins.
