Problème après l'authentification sur Symfony 4

Bonjour @tous,

App\Entity\User: bcrypt

    ROLE_ADMIN:       [ROLE_AUTHOR, ROLE_USER, ROLE_ETUDIANT, ROLE_ALLOWED_TO_SWITCH]

# Easy way to control access for large sections of your site

access_control:
     - { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY }
     - { path: ^/register, roles: IS_AUTHENTICATED_ANONYMOUSLY }
     - { path: ^/admin, roles: ROLE_ADMIN }
