Implementing OpenID in ASP.net “Properly” - Membership or Authentication Provider?

Question

There are several ways to use OpenID on ASP.net sites, but none of them seem to use the existing mechanism of Membership and Authentication Providers.

I wonder what

Answer 1

The Membership API that ASP.NET defines doesn't fit well at all with OpenID, which is probably why you don't see many systems using it. I haven't seen a need to use the Membership provider with OpenID yet, so it hasn't really become an issue. One project that attempted to make the Membership provider model fit with OpenID is http://code.google.com/p/dotnet-membership-provider/, but it doesn't look like it's been maintained recently.

As womp said, you don't need to redo the FormsAuthenticationModule. It works perfectly well with OpenID.

Check out the project templates that come with DotNetOpenAuth to see how things can work without the membership provider.
