facebook with openid

Referencing Is Facebook an OpenID provider? here. This is kind of an additional question based on it.

I have also read the article at : What is the "openid" url of facebook? - but I am still pretty confused on the whole开发者_StackOverflow ordeal. The goal is for people who use facebook to easily login to our website, not to neccessarily integrate with facebook and add things to it (yet). I have read the documentation on facebook connect and am still having trouble grasping exactly what we need to do to accomplish this.

I notice that it says that facebook accepts openid logins - so in theory someone with a facebook account could login to a site that took other openid logins, correct? Or do I have to code a separate 'facebookconnect' system just to accept logins from facebook accounts?

There is a difference between an OpenID provider (who gives you a URL you can log into other sites with) and an OpenID consumer (who lets you log into their site using an OpenID URL).

Someone who "accepts openid logins" sounds like a consumer, but your description "someone with a facebook account could login to a site that took other openid logins" is describing a provider.

There's nothing stopping a site being both a consumer and a provider, but as far as I know, Facebook isn't one.

You have to code a separate "Facebook Connect" system just to accept logins from Facebook accounts, they do not use the OpenID standard.

RPX is a commercial service that offers a way to cut down on some of the confusion.
