Title: AuthorizeAttribute integration with existing MVC authentication

We discussed this briefly in google group.
Looks at HttpContext.Current and did the same authorization asp.net does. Looks at IsAuthenticated and checks the roles the user is in. This is great for those of us with existing authorization/authentication already built that we cannot do a wholesale switchover to ss things [yet].
