I am completely new to dot net nuke. I want to create a module that will hook in to the dot net nuke authentication system and essentially log a user in based on an outside push that the module will be listening for. I don't want to create an authentication system that uses external databases or anything, I want to hook in to the existing dot net nuke authentication provider.

There are some pages that hint at this, but they are for dotnetnuke 5 and things seem to have changed since then.

I don't want to necessarily create a new authentication system, I want to ideally hook in to the existing system from my module. Where on earth do I even start?
