Im using Janrains OpenId-Enabled libs to handle OpenID authentication as a consumer.
Authorization works fine so far. The problem is: I couldn´t find out how I can confirm if a user allready authorized me without beginning the whole process ($consumer->beginn(), $consumer->complete()) anew (thus redirecting the user or using a popup).
Zend-Frameworks openid implementation has a so called 'immediate check' function for this ($consumer->check()). I have found nothing alike in the janrain libs.
On successful authorization I get a lot of interesting GET parameters like 'openid_sig', 'openid_identity' or 'openid_assoc_handle'. Maybe I could use one of those for later authorization confirmation... But how?
Any help is appreciated! thx!
