openid-provider

I love StackExhchange / StackOverflow's approach to integrating OpenID. As I understand it, the process goes something like this: If a user signs up with an OpenID provider (i.e. Google), StackOverflow (or similar site) creates an account for the user and associates the OpenID with that account. An existing user can associate multiple OpenID accounts with his/her StackExchange account. I would love to emulate this behavior because I haven't seen it nearly as user-friendly on other sites. I know StackExchange is built on ASP.NET MVC, but am not sure whether it uses the standard ASP.NET

For example: We're running a two community sites on two domains (call them example.com and example.net ). We want to be able to expand that to more domains later. We want to allow multiple types of login (OpenID, Facebook, Twitter, standard username/password). We want someone who's logged into one site to automatically be logged into the other(s). In other words, it's a bit similar to the StackExchange network. In this case, would this plan work? Set up example.com and example.net (and any later additions) as OpenID relying parties, which accept OpenID login from id.example.org only. Set up

I have searched high, low, far and wide but can not find anything on the Internet that lists the available attributes for these schemas. Does anyone know where the documentation is for these? so far I know of: http://axschema.org/namePerson/first http://axschema.org/namePerson/last http://axschema.org/contact/email http://schemas.openid.net/ax/api/user_id Well I cannot see axschema.org online anymore. But based on http://groups.google.com/group/axschema/browse_thread/thread/49312a23a7d5ecce# I think [ http://openid.net/schema] superseeds [ http://axschema.org] . Here is the list, also on http:

I'm confused about facebook and whether or not facebook is an openid provider like google. According to this link: http://developers.facebook.com/blog/post/246/ , facebook is an openid relying party. What does that mean, and is that different from an openid provider like google. Basically, I am currently using lightopenid to allow users to use their openid's to log into my site, but can't seem to find a url for facebook's openid authentication to do this. I have seen a question similar to this which confuses me because in that question, the questioner was told that facebook is not an openid

Is Facebook an OpenID provider? I know they are an OpenID supporter but do they allow people to authenticate with other sites via OpenID with their Facebook credentials? Adam Albrecht No, they're not an OpenId provider. They use their own OpenID-like system called Facebook connect, which you can use to authenticate users on your site, among other features. You can check it out here: https://developers.facebook.com/docs/facebook-login There is an unofficial Facebook OpenID Provider available at: http://facebook-openid.appspot.com/ You can eaisly use it to log in any OpenID site with Facebook
