To briefly answer your question, you can't programatically set User.Identity.IsAuthenticated because that property is a function of whether or not the user is authenticated. That would be a bit like allowing a cook to mark orders as "complete" with no regard to where in the cooking process they are. You wouldn't let a cook say an order is "done" when he or she hasn't even taken the ingredients out of the refrigerator, nor would you allow the maitre'd to mark an order as incomplete after the customer has already eaten it.

It seems like you need to find yourself a good tutorial about ASP.NET authentication, and maybe the ASP.NET membership provider (which will be good enough for you until you know enough to make your own).
