Implementing Facebook login using OpenID

开发者_如何学JAVA

Is there an OpenID endpoint that authenticates a Facebook user using OpenID? I have an implementation of an OpenID consumer that uses OpenID login, and I don't care to add yet another login scheme, nor replace it with rpxnow (which would mean transfer of all user identifiers to a third party -- and with a free, ad unsupported service, which won't be able to pay for any subscription fees third party service provider might introduce, that is not something I care to do).

So, is there an OpenID provider for Facebook?

I am looking for a possibly third party provider or an open self-hosted solution. If none exists, I'll implement OAuth.

No, Facebook doesn't support OpenID. Use Facebook OAuth authentication
