So you can change username/password and login will still work. - If login using session ID fails and cookie file exists, it will be deleted and a login with username and password is tried the next time the plugin is executed If you start the script with -vvv you can see if login is down with auth session or with username/password... I didn't test it with oVirt 3.2 (yet), but works fine in RHEV 3.1.
