i developed a login form that allows the use of openID. Works fine for most users, but this user has a .mp address. The openID connection keeps on failing.
i tracked down the .mp domain to the provider http://chi.mp (yeah, i know).
I use the simpleOpenId php class to perform the connexion. It returns no error, just dies silently.
Anybody has idea on where this issue comes from?
UPDATE:
As suggested, i've set up the Janrain library at http://openidenabled.com/php-openid/ as that works with OpenID 2.x.
Alas, same goes here: login in using .. works, but .mp does not. It says "Authentication error; not a valid OpenID."
You can try it for yourself here.
