I'm developing an application within DotNetNuke where a user can book an appointment online with the client firm. I have got booking working, and now I need to give the user an easy way to log in for the appointment. Has anyone tried setting up something like a kiosk in DotNetNuke? I want the user to log in using their user credentials, but then not have access to the rest of the system. They should only be able to select a link that logs them into the appointment (i.e. save a record in the database of their presence), and then log them out again and return to the kiosk. Ideas? Should I just write a module to handle this that's public, takes their credentials, and saves them in session but doesn't "really" log them in?
