Im new to symfony2 version 3.0 and Im trying to create a login form. But I'm stuck in security.yml configuration and I dont know whats going on. Im been searching in google for 3 hours but no luck. Hope you can help me. So far here is my code.


Every time I go to http://localhost:8000/admin it gives me this error

The check_path "user/login-check" for login method "form_login" is not matched by the firewall pattern "^/admin".

Invalid configuration for path "security.firewalls.secured_area": The check_path "user/login-check" for login method "form_login" is not matched by the firewall pattern "^/admin".

What I have tried:

security:
encoders:
AppBundle\Entity\User:
algorithm: bcrypt

providers:
db_provider:
entity:
class: AppBundle:User
property: username

firewalls:
login_area:
pattern: ^/user/login$
security: false

secured_area:
pattern: ^/admin
anonymous: ~
form_login:
login_path: user/login
check_path: user/login-check
always_use_default_target_path: true
default_target_path: /admin
provider: db_provider
