title: keycloak remove default roles that are added automatically
body: <p>I am using keycloak 12.0.4 and I want new local or synced federated users to not have default roles. when we create the realm from the JSON file... it still always add &quot;uma_authentication&quot; and &quot;offline_access&quot; why?
  Even if I put an empty list and if I add a list with other roles.
  it adds the role and this two roles also.</p>
  <p>Is there a way to remove those? without the need to update the realm?</p>
