Bugfix
If you use OpenID for the login, then normally no login page is displayed, but a direct forwarding to the OpenID provider takes place. After logging out of the application, however, the logout page must not redirect directly to the OpenID login or to the local login page. In the first case, it would otherwise not be possible to log out at all, as a login would take place immediately, and in the second case it would not be possible to log in again, as the local login page does not offer the option to jump to the OpenID login.
