Multiple domains (for managed services partners only)
If you are a Managed Services Partner, you need the capability of managing multiple, independent hierarchies--one for each of your client companies. As an MSP, you will define a unique domain for each of your customers. When you add or delete attributes, you can do so for all domains or you can select specific domains to apply changes.
A domain is associated with a host group hierarchy and all newly discovered hosts are added to the root host group associated with the domain. Each MSP customer will have a separate domain with its own hierarchy.
A host group can only serve as the root for one domain. For example, you could have a host group defined for Acme Corp and then create an Acme Domain that uses the host group as the root of its host group hierarchy. Once a domain is associated with a host group, this host group cannot become the root of any other domain.
