sec.userSetRoles( user-name as String, role-names as String[] ) as null
  Assigns the user with name $user-name to have the roles identified by
  $role-names.  Removes previously assigned roles.
  If a user with name equal to $user-name is not found, an error is 
  returned.
  If a role name in $role-names does not correspond to an existing role,
  an error is returned.
  If $role-names is the empty sequence, all existing roles for the user are 
  removed.
  If the current user is limited to granting only his/her roles,
  and $role-names is not a subset of the current user's roles or one
  of the removed roles is not a subset of the current user's roles,
  then an error is returned.
