Idle time forced logout

[Jan Henkins <jan henkins za net>]

Hello all,

Is there a module where one can force a user to log out after a certain amount 
of idle time? I tried a number of "traditional" methods (idled and a few 
other methods), but none works properly in an environment where display 
managers like GDM/XDM is used as the login method.

Any ideas?
