It's rather a normal thing to do on Unix, but if you have reason to prevent
it, then in /etc/profile or /etc/cshrc, grep for that users's name in the
output of 'w', and do what you decide.

You'd have to have some code which checks at login time to see if
someone is already logged on using that account. If the user has no
write access to their .profile or .login, that would be the best place for
it; otherwise, you could put it in /etc/profile or /etc/cshrc, and be
careful to make it apply only to the user account(s) which are to be
protected in this way.

I think this is a little dirty ,but as first idea.
You can change access rights to pseudo Terminals.
For every user only one pseudo terminal.
But this prevents only in tcp environments.
When you have both network terminals / serial terminals
the user can still connect more times to the system.

That sounds complicated. Just write some tests in /etc/profile or
/etc/cshrc.
