Customizing the Schema
You can extend the standard schema if it proves to be too limited for your
directory needs. To help you extend your schema, the Directory Server includes a
schema management tool. For more information, see Red Hat Directory Server
Administrator's Guide.
Keep the following rules in mind when customizing your schema:
• Reuse existing schema elements whenever possible.
• Minimize the number of mandatory attributes you define for each object class.
• Do not define more than one object class or attribute for the same purpose.
• Keep the schema as simple as possible.
• Do not modify any existing definitions of attributes or object classes.

Your custom object classes and attributes are defined in the following file:
