Show flashbag message by required user role

Question

When I secure a certain area of my Symfony2 project by the firewall, people are being redirected to the login page. How can I display a dynamic message on that login page, that tells the user about the required user role?

E.g. there are four different pages on my project

/ is not restricted,
/admin requires ROLE_ADMIN,
/user requires ROLE_USER,
/beta requires ROLE_BETA_USER.

If the user tries to access /beta, above the login page there shall be the information

This area is restricted to beta users.

... and accordingly for /admin and /user. Is there a way to set this message globally (without having to set it on each controller action separately)?

You could do it by implementing AccessDeniedHandlerInterface.

In handle method you can check request path and add appropriate flash message.

You will have to register your AccessDeniedHandler service in security.yml:

security:
    firewalls:
        main:
            access_denied_handler: my.access_denied_handler_service_name

This sounds promising. I'll have a look on that! – Gottlieb Notschnabel Jan 12 '15 at 16:26
Can you provide examples of the service definition and the handler class? I'm at a loss here... – Gottlieb Notschnabel Jan 12 '15 at 16:38
This is what I tried: https://gist.github.com/anonymous/536e142c5bc49d3927c8 but I simply get redirected to login without any handling by my service. – Gottlieb Notschnabel Jan 12 '15 at 18:37

That's the example I applied, just taking out the service arguments and modified the return. But will this break the result? – Gottlieb Notschnabel Jan 12 '15 at 19:21
