[keycloak-user] Keycloak and AEM

Hi there! I have AEM publish instance behind dispatcher (www.someaddress.com) and keycloak instance (localhost:8080). I would like to perform a GET to /auth/realms/my-realm/protocol/saml/clients/dialogo-samlIDP in order to fetch kc-form-login markup however I'm getting: Failed to load http://localhost:8080/auth/realms/my-realm/protocol/saml/clients/dialogo-...: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.someaddress.com' is therefore not allowed access. How can I setup this on keycloak side?
