[keycloak-user] JAX-RS Backend Service + Angular 2 Front-End + Role Authorization

Hello everyone. I am developing a web application with Angular 2 on the front end, and jax-rs services on the backend, I also need authorization with user roles but I have the following problems: 1. The recommendation in the documentation is to establish the angular customer as public, which means that the authorization can not go here. 2. If the backend is set as the confidential customer, the service can not be consumed from angular 2 with the barer symbol. 3. If the backend is configured as a barer only client, the roles are not validated on the authorization defined in keycloak. Can you help me find a better configuration for this environment? Thank you all. Gaalvarez.
