OpenID - How do I check if an OpenID user is logged in?
Posted: Mon Mar 02, 2009 11:44 am
Slightly off-topic, I guess, but I am using PHP to implement it...
Right now I have figured out how to direct a user to an OpenID provider and log him in. The thing which I do not know is how do I know beforehand if he has already logged in before he visits my site? Or that is not the intention of the OpenID at all and the user should log-in again, with his OpenID, at my site and choose whether to associate my site with his OpenID?
