Authenticate against Admin Session

If you want to authenticate against an existing admin session, you can use the provided pimcore_admin_pre_auth authenticator. The authenticator does not handle authentication, but just returns a pre authenticated token if there's an existing admin session. To use the authenticator, just enable it on your firewall configuration:

security:
    firewalls:
        demo_cms_fw:
            pimcore_admin_pre_auth: ~
