Here at school we are working with a 802.1X network with certificate. On Windows laptops we work with SecureW2 which shows the student a login box where they have to fill in their credentials. Problem is that i worked it out with Lion how to connect to the 802.1X network. It works this time with a .mobileconfig, but problem is that it saves the credentials. Why? Because we use rental Macbooks. They can rent it for a few days, so it is not done to save the credentials. Is there any way to show the student a login box after each restart? So we dont have to image the MBP when it comes back?
