The tests cheat at filling out web forms by directly POSTing to the target. The target for authURLs has changed slightly, the base authURL now redirects the user to the login page. Additionally, the authURL cycle now checks the cookie is set correctly, so we add cookie jars where necessary to pass the cookie through.
