Automatically assign authentication token in .NET

Question

I have implemented forms authentication with a .NET Membership Provider but I also want users to be able to login with Facebook. Once authenticated with Facebook, I want to automatically assign a .NET authentication token to the user. I have a HttpModule that is detecting the FB authentication but all my attempts to manually generate an authentication token have come up short.

I tried

• FormsAuthentication.SetAuthCookie
• FormsAuthentication.GetAuthCookie + Response.Cookies.Add
• new FormsAuthenticationTicket(...) a la MSDN
• In an HttpModule vs Page

Plus a few other desperate attempts. Nothing seems to work. How is this done?

Answer 1

It turns out someone else had registered another module in the solution that was interfering with HttpRequest and the authentication pieces. After I got rid of that, FormsAuthentication.SetAuthCookie(...) worked fine.

Thanks everyone for the help.
