Symfony2.1: Unable to find the controller for path “/login_check”

Question

I used the "Using a traditional login form" tutorial from symfony.com to authentificate my users. With a simple http auth it works great.

After the login was submitted I get this Exception:

Unable to find the controller for path "/login_check". Maybe you forgot to add the matching route in your routing configuration?

Well, in the tutorial I read:

You will not need to implement a controller for the /login_check URL as the firewall will automatically catch and process any form submitted to this URL.

I defined the routes and set the firewall settings:

security.yml

firewalls:
    dev:
        pattern:  ^/(_(profiler|wdt)|css|images|js)/
        security: false
    backend:
        pattern:    ^/backend
        anonymous: ~
        form_login:
            provider: entity
            login_path: /login
            check_path: /login_check
            #use_forward: true
        logout:
            path:   /logout
            target: /

routing.yml

login:
    pattern:   /login
    defaults:  { _controller: VitaSecurityBundle:Default:login }
login_check:
    pattern:   /login_check
logout:
    pattern:   /logout

Answer 1

The problem you are having is described here:

See http://symfony.com/doc/current/book/security.html , section "Avoid Common Pitfalls"

1. Be sure /login_check is behind a firewall Next, make sure that your check_path URL (eg /login_check) is behind the firewall you're using for your form login (in this example, the single firewall matches all URLs, including /login_check). If /login_check doesn't match any firewall, you'll receive a Unable to find the controller for path "/login_check" exception.

In this example, your pattern specifies a prefix of /backend for secured paths. To work, your login check should be behind this same firewall.

So, to match the pattern which you have specified in your firewall, put login_check on a url path like this: /backend/login_check

I found the solution to my problem

I added the /backend prefix to my paths, removed the 'anonymous: ~' line and commented out the ACL for backend.

security.yml

    firewalls:
    dev:
        pattern:  ^/(_(profiler|wdt)|css|images|js)/
        security: false
    login_firewall:
        pattern:    ^/backend/login$
        anonymous:  ~
    backend:
        pattern:    ^/backend
        form_login:
            provider: entity
            login_path: /backend/login
            check_path: /backend/login_check
            #use_forward: true
        logout:
            path:   /backend/logout
            target: /

access_control:
    #- { path: ^/backend, roles: ROLE_USER }

routing.yml

login:
    pattern:   /backend/login
    defaults:  { _controller: VitaSecurityBundle:Default:login }
login_check:
    pattern:   /backend/login_check
logout:
    pattern:   /backend/logout

Answer 3

The problem also tends to happen when you have two firewall with the same pattern. For example:

....
 backend:
            pattern:        ^/*
....
 frontend:
            pattern:        ^/*

You must change one of the two as follows:

....
 backend:
            pattern:        ^/(administrador|backend)/*
....
frontend:
            pattern:        ^/*

Here is a sample code I used in a real-life project:

firewalls:
    dev:
        pattern:  ^/(_(profiler|wdt)|css|images|js)/
        security: false

    secured_area:
        pattern:    ^/cmd
        anonymous: ~
        form_login:
            check_path: /cmd/login_check
            login_path: /cmd/login
        remember_me:
            always_remember_me: true
            key:      "%secret%"
            path:     /cmd
            domain:   ~ # Defaults to the current domain from $_SERVER
        logout:
            path:   /cmd/logout
            target: /

    admin:
        pattern: ^/admin
        http_basic:
            realm: "Administration"

    free_area:
        pattern: ^/
        anonymous: ~

In my case, only the /cmd/ part is secured, the /admin/ part is also secured, but with HTTP security.

Maybe you should try: security.yml

firewalls:
    dev:
        pattern:  ^/(_(profiler|wdt)|css|images|js)/
        security: false
    backend:
        pattern:    ^/backend
        anonymous: ~
        form_login:
            provider: entity
            login_path: /backend/login
            check_path: /backend/login_check
            #use_forward: true
        logout:
            path:   /backend/logout
            target: /

and as of routing.yml:

login:
    pattern:   /backend/login
    defaults:  { _controller: VitaSecurityBundle:Default:login }
login_check:
    pattern:   /backend/login_check
logout:
    pattern:   /backend/logout

I think your problem might come from the fact security is not activated in your / part (the pattern of your secured area is ^/backend)

Answer 5

This was not workging for me and I try something else :

firewalls:
    dev:
        pattern:    ^/(_profiler|_wdt|css|js)
        security:   false

    login:
        pattern: ^/login$
        security: false

    secured_area:
        pattern: /(admin/.*|login_check)
        provider: in_memory
        form_login:
            check_path: /login_check
            login_path: /login
            default_target_path: /admin
            always_use_default_target_path: true
        logout:
            path:   /logout
            target: /

access_control:
    - { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/, roles: ROLE_ADMIN }

With the following explanation, simpler than the explanation from zabojad. The important thing is to put the login_check route inside a firewall and to let the login outside. With a or pattern you can succeed.
