Where to Search
An object can be in one of the following naming contexts:
Domain. This contains most of the highly used objects such as users, contacts, groups, organizational units, computers, and so on. Most queries will search a domain.
Schema container. This contains the attributeSchema and classSchema objects that define the types of objects and properties that can exist in the directory.
Configuration container. This contains configuration information that is relevant to the entire forest, such as sites, display specifiers, extended rights, partitions, and so on.
Global catalog. This contains a partial replica of all objects in the directory. It includes partial replicas of all domains in the forest as well as partial replicas of the schema and configuration containers.
