Multiple Master Domain

The multiple master domain model provides centralized administration for large companies organized by groups, departments, or locations. Because this model can be expanded easily, it is useful for organizations that anticipate substantial growth.

With the multiple master domain model, two or more single master domains are connected by a two-way trust relationship. The master domains serve as account domains, with every user account created and maintained on one of the master domains. The resource domains don't store or manage user accounts, but do provide resources such as shared file servers and printers. Each resource domain trusts all master domains in a one-way trust relationship. A resource domain can trust other resource domains but is not required to do so.
