providers:
    fos_userbundle:
        id: fos_user.user_provider.username

firewalls:
    main:
        pattern: ^/
        form_login:
            provider: fos_userbundle
            csrf_provider: form.csrf_provider
            login_path:                     /login
            use_forward:                    false
            check_path:                     /login_check
            post_only:                      true

            csrf_parameter:                 _csrf_token
            intention:                      authenticate
        logout:       true
        anonymous:    true
access_control:
    - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/, role: ROLE_ADMIN }

Answer 1

After you authenticate you are being set another role then ROLE_ADMIN. Please use the app_dev.php version of the site and at bottom it will tell you your role after you access the access denied page.
