We are using nw 6.5 sp7

The problem we have run into, thank you auditors, a persons password is set
to expire on say 9-1-2008, they never log their work station off and re-log
in, so it never asks them to change their password.

I could set an inactivity timeout that would log them off in the middle of
the night, but we have some people who have to be logged on for extended
periods over night to run automated jobs and timing them out would not be a
good thing.

Is their any other way to force a logoff or password change when a users
password expires but they haven't logged off?
