Is anyone using Novell's single sign-on feature? I am in a k-12 environment and some computers are shared by several teachers. The student computers are Zen'd so I have no problem there. The teacher computers do not use Zen (for reasons I don't want to explain now). They complain about having to logon to Novell and then into Windows. How involved is it to set up Single sign-on? Any info/feedback is appreciated.
