according to http://www.nabble.com/How-to-set-up-OpenID-authentication-to25571181.html there are some bugs with OpenID

Unfortunately, Zend_Openid has a few issues. I started doing some testing last week and will roll in some fixes in a while. In the meantime, I suggest reverting to something like the Janrain PHP library while this is being fixed.
