Hi Levi, I plan to put it on the Wiki but I've been holding off because of
a few glitches, for example I'd like pam_mount to only create a mount for
shares that a user has any business using. RIght now pam_mount creates
shares for the teacher and the student for every domain user logging on.
So the log on process is delayed slightly. But logons are still only <10
seconds, which is about 10-20 seconds faster than my XP machines (with
Roaming Profiles and Deep Freeze...) usually!
Also, my script seems a little primitive. Maybe others have a better
solution?
