Before starting, I'd like to thank all contribs to this module, as it is a rich add-on to every wordpress installation :)
That being said, I'm finding some trouble trying to log in into another target site (in fact, another wordpress site) using my author URL as an OpenID. I am able to post comments into the same target site identifying myself with the same author url, but I can't neither create an account/log in with the url nor add the URL to «my openid sites» using the dashboard interface.
I'm using both the latest versions of WordPress and the plugin. The original site has the OpenID provider activated to the role of my user (that's why I can post comments using the author url as openid).
