TYPO3.Flow

FLOW3 already comes with an Authentication Controller that even supports redirection to the intercepted request after successful authentication (if a WebRedirect EntryPoint was configured).

We should provide an abstract base class that developers can extend from in their own packages.
The API could be s.th. like

 1 abstract class AbstractAuthenticationController extends \TYPO3\FLOW3\Mvc\Controller\ActionController {
 2 
 3 public function indexAction();
 4 
 5 final public function authenticateAction();
 6 
 7 public function logoutAction();
 8 
 9 abstract protected function onSuccessfulAuthentication(\TYPO3\FLOW3\Mvc\ActionRequest $interceptedRequest);
10 
11 abstract protected function onErroneousAuthentication();
12 
13 }
