ARTICLE:
An Active Directory Structure is
an arrangement of information about Objects
The objects fall into two broad categories: resources (e.g., printers) and security principals (user or computer accounts and
groups). Security principals are assigned unique security identifiers (SIDs).
Each object represents a single
entity—whether a user, a computer, a printer, or a group—and its attributes.
Certain objects can contain other objects. An object is uniquely identified by
its name and has a set of attributes—the characteristics and information that
the object represents— defined by a schema,
which also determines the kinds of objects that can be stored in Active Directory.
The schema
object lets administrators
extend or modify the schema when necessary. However, because each schema object
is integral to the definition of Active Directory objects,
deactivating or changing these objects can fundamentally change or disrupt a
deployment. Schema changes automatically propagate throughout the system. Once
created, an object can only be deactivated—not deleted. Changing the schema
usually requires planning.
