Appendix B -- Base Schema Class Objects

Schema class objects describe the possible Active Directory objects that can be created, functioning as a template for creating new Active Directory objects. The base schema class objects are the basic set of schema class objects shipped with Windows 2000 Server. If the base schema doesn't meet the needs of your organization, you must consider modifying the schema or creating additional schema class and/or attribute objects; this process is called extending the schema. To determine whether the base schema objects meet the needs of your organization, you must familiarize yourself with the base schema class objects listed in this appendix and the base schema attribute objects listed in Appendix C. If you know the types of data that Active Directory will hold, you can more effectively determine whether you need to change the base schema and whom the changes will impact.
