Symfony2 Redirection for unauthorised page with access_denied_url

Question

I'm trying to use the access_denied_url parameter in security.yml

The problem is that... it does nothing. When I access to /mon-equipement as anonymous, it keeps redirecting me to /login

Here is my security.yml file :

security:
    encoders:
        FOS\UserBundle\Model\UserInterface: sha512

    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER

    providers:
        fos_userbundle:
            id: fos_user.user_provider.username

    firewalls:
        main:
            pattern: ^/
            form_login:
                provider: fos_userbundle
                csrf_provider: form.csrf_provider


                always_use_default_target_path: false
                default_target_path:            /mon-equipement
                target_path_parameter:          _target_path
                use_referer:                    false
            logout:       true
            anonymous:    true
            access_denied_url: /

    access_control:
        - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/mon-equipement, role: ROLE_USER }
        - { path: ^/admin/, role: ROLE_ADMIN }

I'm using FOSUserBundle with Symfony2.3.16

Answer 1

I think your access_controll section should looks like this:

access_control:
    - { path: ^/$, roles: IS_AUTHENTICATED_ANONYMOUSLY }
    # ... here the other routes

Your problem: It redirects you on the / page, but you have no access to this page. Therefore it redirects you on the login page.

UPDATE:

You can also define access_denied_url for all firewalls:

# app/config/security.yml
security:
    access_denied_url: /

Answer 2

First you have to know that access_denied_url is only redirecting non anonymous users. For instance it will redirecte a user with ROLE_MEMBER if it tries to acces a page whose path is only for ROLE_ADMIN.

Here the solution:
You have to create a service ( my_entry_point ) that will be triggered at the entry-point listener (see security.yml below) and which will redirect the user to the page you want ( target_page_for_redirection )

# app/config/security.yml

security:
  firewalls:
    main:
      entry_point: my_entry_point  # listener triggered if no token is set while an authentification is needed (access_control)
      pattern:  ^/

.

#src/Acme/UserBundle/Ressources/Config/services.yml

service
  my_entry_point:
     class: Acme\UserBundle\Redirection\EntryPointRedirection
     arguments: [@router] #needed for URL redirection

.

<?php
namespace Acme\UserBundle\Redirection;

use Symfony\Component\Security\Http\EntryPoint\AuthenticationEntryPointInterface,
    Symfony\Component\HttpFoundation\Request,
    Symfony\Component\HttpFoundation\RedirectResponse;

class EntryPointRedirection implements AuthenticationEntryPointInterface
{
   protected $router;

   public function __construct($router)
   {
      $this->router = $router;
   }

   public function start(Request $request, AuthenticationException $authException = null)
   {
      return new RedirectResponse($this->router->generate('target_page_for_redirection'));
   }
}
