Symfony2: Unable to find the controller for path "/login_check"

Question

I use FOSUserBundle and FOSFacebookBundle together. I set them abiding by official documentation:

FOSUserBundle and FOSFacebookBundle

When I log in using the facebook button I see:

Unable to find the controller for path "/login_check". Maybe you forgot to add the matching route in your routing configuration?<br />
404 Not Found - NotFoundHttpException</p>

Answer 1

In your app/config/routing you have the /login_check without a controller assigned. You have to configure a controller like this:

_security_check:
    pattern: /login_check
    defaults: { _controller: ACMEBundle:Controller:action }

You can find more information at http://symfony.com/doc/current/book/routing.html

Now The routing system finds first instead the one configured in "@FOSUserBundle/Resources/config/routing/security.xml". If you want that FOSUserBundle handles the login process you have to delete the _security_check and _security_logout routes.
