# Easy way to control access for large sections of your site
# Note: Only the *first* access control that matches will be used
access_control:
    # - { path: ^/admin, roles: ROLE_ADMIN }
    # - { path: ^/profile, roles: ROLE_USER }

    # matches /admin/users/*
    - { path: ^/admin/users, roles: ROLE_SUPER_ADMIN }

    # matches /admin/* except for anything matching the above rule
    - { path: ^/admin, roles: ROLE_ADMIN }
