> The ShellUserGroupProvider can produce a Set<String> user identifiers with a
> null entry when there are no members of a group.
> Also, the front end component displays users and groups in the same grid and
> requires each entity have a unique id, so the user and group UUIDs should be
> seeded with some kind of differentiator like "-user" or "-group" to handle
> the case where a user and group with the same name exist.
