Symfony2 admin token in public area - php

Question

I'm having trouble getting security to work the way I want it.
I want administration part to be protected so only people with ROLE_ADMIN can access it. And that works just fine. However, I want my unprotected/public area to be able to differentiate between ROLE_ADMIN and IS_AUTHENTICATED_ANONYMOUSLY.
I can't make it work though. After I log in into admin section. I can see in toolbar that I'm authenticated and have ROLE_ADMIN, but as soon as I go back to public section of the website it turns into anonymously authenticated.
Here is security setup I currently have:
jms_security_extra:
secure_all_services: false
expressions: true
security:
encoders:
Symfony\Component\Security\Core\User\User: plaintext
role_hierarchy:
ROLE_ADMIN: ROLE_USER
ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]
providers:
in_memory:
memory:
users:
myusername: { password: mypassword, roles: [ 'ROLE_ADMIN' ] }
firewalls:
dev:
pattern: ^/(_(profiler|wdt)|css|images|js)/
security: false
login_area:
pattern: ^/login$
anonymous: ~
secured_area:
pattern: ^/admin|^/login_check$|^/logout$
form_login: ~
logout: ~
public_area:
pattern: ^/
anonymous: ~
access_control:
- { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/admin, roles: ROLE_ADMIN }
- { path: ^/, roles: [ROLE_ADMIN, IS_AUTHENTICATED_ANONYMOUSLY] }
As you can see I tried adding both ROLE_ADMIN and IS_AUTHENTICATED_ANONYMOUSLY roles to '^/' path in access control, but it doesn't change anything.
I searched both Symfony2 book and Cookbook entries but didn't find anything that would help me regarding this problem.

Ok, and just 20 minutes later, after digging the Symfony2 book for the third time I found this:
Multiple firewalls don't share security context
If you're using multiple firewalls and you authenticate against one firewall, you will not be authenticated against any other firewalls automatically.
It was enough to just use one firewall on '^/' pattern and set access_control to this:
- { path: ^/admin, roles: ROLE_ADMIN }
- { path: ^/, roles: IS_AUTHENTICATED_ANONYMOUSLY }
