[OpenAFS] Renew tokens with screensaver

[Jared Smith]

I have a handful of ubuntu users that get their tokens renewed every 
time they put there password in to remove their screensavers.  Makes it 
really nice and seemless.  Now I have a bunch of users switch to Windows 
and they have to renew after 7 days.  Wondering if there is something 
similar like that for windows 7/vista/xp?  I have done some google 
searching but not turning up anything.

Thanks,
Jared
