Dynamic Auxiliary Classes
Similar to structural and abstract object classes, auxiliary classes are defined by a classSchema object in the Active Directory schema. For more information, see Structural, Abstract, and Auxiliary Classes. This schema definition specifies various characteristics of the class, including the attributes associated with the class.
Unlike with structural classes, You cannot create an instance of an auxiliary class as you can with a structural class. Instead, you use an auxiliary class to extend the list of attributes that is associated with another structural, abstract, or auxiliary object class.
In the initial release of Windows 2000, Active Directory Domain Services provided support for statically linking auxiliary classes to the classSchema definition of another object class. When an auxiliary class is used in this way, every instance of the object class supports the attributes of the auxiliary class.
Windows 2000 Server and earlier: Active Directory Domain Services does not provide support for dynamically linking auxiliary classes to individual objects, and not just to entire classes of objects. In addition, auxiliary classes that have been attached to an object instance cannot subsequently be removed from the instance.
Windows Server 2003: Dynamic Auxiliary Classes are supported when all domain controllers in the forest are running Windows Server 2003 and the forest functional mode is Windows Server 2003.
