Definition of object classes

You can define object classes by the characteristics of type, inheritance, and attributes.

Object class type
An object class can be one of three types, structural, abstract, and auxiliary.
Object class inheritance
IBM® Security Directory Server supports object inheritance for object class and attribute definitions. A new object class can be defined with parent classes (multiple inheritance) and the additional or changed attributes.
Attributes
Every object class includes a number of required attributes and optional attributes. Required attributes are the attributes that must be present in entries by using the object class. Optional attributes are the attributes that might be present in entries by using the object class.
