In these cases, it is sometimes appropriate for the Identity Management System to refer to a single, aggregate system, and sometimes appropriate to differentiate between its components. For example, a user may be known to exist on the system as a whole, but password updates may have to be performed on each component.
A Sub-Host is one component of such an aggregate system.
