I am not new to symfony by any means, but I\'ve always used FOSUserBundle which by default prevents one from having 2 different login forms for authenticating t
The problem is that after logging into the "secured_area" firewall you get redirect to "/" which is behind the "members_area" firewall. You can't access "members_area" with your credentials from "secured_area" (at least not by default). Read the details on http://symfony.com/doc/current/reference/configuration/security.html#reference-security-firewall-context .
If you have a look at the security configuration (http://symfony.com/doc/current/reference/configuration/security.html) you can see that the default_target_path for form_login is "/". Just change this to /admin:
security:
...
firewalls:
...
secured_area:
pattern: ^/admin
...
form_login:
check_path: /admin/login_check
login_path: /admin/login
default_target_path: /admin
logout:
...
The alternative is to share the context as described in the first link (http://symfony.com/doc/current/reference/configuration/security.html#reference-security-firewall-context).
