You can't, and even if you could the user could just run a second copy
of bash to get around it.

How do you want to define an idle user? Someone who hasn't typed any
shell commands, or someone who hasn't interacted with any program at
all?

If you're looking for security and you don't want unattended screens
and you're running under X, the best way is with one of the
screensavers/lockers. You can configure how long to wait after *any
keystroke or mouse movement* to activate screen lock.

If you actually want to log them out, I'm not sure if there is a
program to do that. It would be pretty easy to grab the code from a
screen saver and instead of activating screen save on an idle
terminal, do a "ps -aux | grep username | xargs kill ; sleep 20 ; ps
-aux | grep username | xargs kill -9"
