class. The structural class is important to
the system administrator in that it is the only type from which new
Active Directory objects are created. Structural classes are developed
from either the modification of an existing structural type or the use of
one or more abstract classes.
class. Abstract classes are so named because
they take the form of templates that actually create other templates
(abstracts) and structural and auxiliary classes. Think of abstract
classes as frameworks for the defining objects.
class. The auxiliary class is a list of
attributes. Rather than apply numerous attributes when creating a
structural class, it provides a streamlined alternative by applying a
combination of attributes with a single include action.
88 class. The 88 class includes
object classes defined prior to 1993, when the 1988 X.500 specification
was adopted. This type does not use the structural, abstract, and auxiliary
definitions, nor is it in common use for the development of objects in
Windows Server 2003 environments.
