root password timeout

[Konstantin Svist <fry.kun@xxxxxxxxx>]

Where is the timeout setting for remembering the root password for 
various system-controlling applets?

For instance, if you open system-config-network, it asks you for a 
password the first time - but then it remembers it for a few minutes. 
Within that time you can close & reopen the  network config applet, and 
most other admin applets, as well. I'd like to make my computer timeout 
immediately, if possible.

Also, is there a way to manually override the timeout (force it to time 
out on command)? E.g. if I need to quickly change a setting and then let 
someone else work on the computer.


BTW, I'm using KDE - but I suspect that these applets were written for 
gnome.
