title: Which PHP OpenID server/provider library do you recommend?
body: <p>I am just wondering what PHP OpenID server (some here <a href="http://wiki.openid.net/w/page/12995226/Run-your-own-identity-server" rel="nofollow">http://wiki.openid.net/w/page/12995226/Run-your-own-identity-server</a>) you all would recommend from your experiences? Any that I should definitely avoid etc?</p>
  
  <p>Im using a XAMPP setup, and looking for something fairly easy to implement, it doesn't have to be extremely robust or anything, just something fairly simple that will support multiple user registrations (with passwords - I think the Janrain php openID server implementation doesnt support passwords as far as I know)</p>
  
  <p>Many thanks!</p>
