Ingo Schommer fbc375a282 mlanthaler:OpenID authentication works now. To use it simple create an user account without password and put your *complete* OpenID identifier in the email field, e.g. "http://markus-lanthaler.myopenid.com/".
You can get a free OpenID from http://www.myopenid.com  (merged from branches/gsoc)
