[keycloak-user] Keycloak policies eval

Hi there, I'm implementing keycloak for authentication in a server with spring boot. I'm doing something like "@RequestMapping("/login") " in java but the policies aren't taken into account, because I can login with every user in the client. I want something like this https://github.com/keycloak/keycloak-quickstarts/blob/latest/app-authz-je..., that tells me if the user can or not access the specific client in a resource. What should I do? Best regards, Simão Silva
