[keycloak-user] role-ldap-mapper oddities

Anyone notice the following oddities with the role-ldap-mapper (Keycloak 5.0.0): 1. It has fewer options than group-ldap-mapper despite doing essentially same thing. * "Drop non-existing groups during sync" is missing (label would be "Drop non-existing roles during sync") * "Ignore Missing Groups" is missing (label would be "Ignore Missing Roles") * Preserve Group Inheritance is missing (label would be "Preserve Role Inheritance") * Mapped Group Attributes is missing? Maybe Roles don't have attributes? This one may not matter 2. Looking up members of a role shows empty set, but looking up the roles of a specific user works (bug?) * Using web admin console "Role" page select a role and see it has empty membership * Using web admin console "User" page select a user and see it has multiple roles including one that was "empty" from the "Role" page
