I don't think that is quite possible. The reason is anytime you log on another user on a machine the settings will change. You'd have to set this up for every single user account on each machine. So for example, if you have 30 users and 30 workstations, on each workstation, you'd have to setup 30 folders with 30 usernames/passwords. You'd have to do this for each user account. That's 900 accounts to setup.. Might take a while.

I think this would work fine if each user had a specific workstation. But if they are moving around to different workstations, that might throw a rod in the spokes.

But I'll wait to see if someone else can answer this, as I may be incorrect.
