[keycloak-user] User Attributes not added in token

Hi Community, I'm new to keycloak. And trying to federate login via external database. While federating username and password validation trough JPA I'm trying to add user attribute to the token. To achieve that all I'm doing is adding the attribute in getAtrributes method. As I'm expecting it then adds to the token. But after successful validation the token I get does not have the 'phone' attribute Is there something I'm missing ? Do I have to add this attribute any other way ? File: public class UserAdapter extends AbstractUserAdapterFederatedStorage @Override public Map<String, List<String>> getAttributes() { Map<String, List<String>> attrs = super.getAttributes(); MultivaluedHashMap<String, String> all = new MultivaluedHashMap<>(); all.putAll(attrs); all.add("phone", userEntity.getMOBILE_NO()); return all; } Kind Regards
