[keycloak-user] Keycloak Filters and Roles

Hello, I am using a java servlet with keycloak filters, so no security constraints can be applied. I would like to know how can I block some HttpMethods for users of a certain role. I created roles in keycloak, I tried to define the auth-constraints within the security-constraints but it always returns error 403 Unauthorized. If I remove the auth constraint and security roles I am able to access the method. It seems that it is not recognizing keycloak roles or not mapping them between the servlet and keycloak. I am blocking the method as shown below in the class: @GET @Path("/get") @RolesAllowed("admin") @Produces(MediaType.TEXT_PLAIN) public String delU(@HeaderParam("user_id")) { ... } And I have the filters like the link below in the web.xml: https://keycloak.gitbooks.io/securing-client-applications-guide/content/v... Best Regards
