Definition of Sub-Host

An Identity Management System may manipulate user accounts on Managed Systems that are implemented as aggregates of smaller systems. Examples of aggregate systems include:

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.
