Active Directory Object Schemas

You may have noticed a property of the IADs object interface called Schema. This property is the Active Directory path to an object that contains a description of the class of each and every object in the Active Directory tree. The schema can be examined to determine what each of the properties in any class are and what their data types are.

The IADsClass Object Interface

If you use the GetObject function to retrieve the schema of an Active Directory class, the object you'll receive will implement the IADsClass object interface. This object interface has the properties in Table 12.8.
