ownCloud OpenID user authentication

Don't expect the login screen to change.

After configuring my OwnCloud local user with a identity at my OpenID provider, the browser is redirected to my auth server right after submitting my OpenID identifier to the OwnCloud login page, so this part of the process works fine.

Unfortunately, the login process does not succeeded because finally I'm redirected to the OwnCloud login page again (it does not show any error, by the way)

Update (Apr 24, 2013):

I've started to look into the code and I've found that OwnCloud uses class.openid.v3.php wich does not seem to support OpenID v2.0 (see https://stackoverflow.com/questions/6724729/has-any-one-got-class-openid-php-working-with-google-openid)

(Please note that this is very preliminary information. Maybe the file class.openid.v3.php supplied with OwnCloud have been upgraded to suport the latest release of OpenID. In fact, http://openid.net/developers/libraries/ says that "Simple OpenID PHP Class" is 2.0 compatible)
