Extending Server Schema

Extending Server Schema
The Directory Server schema includes hundreds of object classes and attributes that
can be used to meet most of your requirements. This schema can be extended with
new object classes and attributes that meet evolving requirements for the directory
service in the enterprise.
When adding new attributes to the schema, a new object class should be created to
contain them (adding a new attribute to an existing object class can compromise
the Directory Server's compatibility with existing LDAP clients that rely on the
standard LDAP schema and may cause difficulties when upgrading the server).
For more information about extending server schema, refer to the Netscape
Directory Server Deployment Guide.

Schema Checking

You should run Directory Server with schema checking turned on.
The schema checking capability of Directory Server checks entries when you add
them to the directory or when you modify them, to verify that:
• Object classes and attributes used in the entry are defined in the directory
schema
• Attributes required for an object class are contained in the entry
• Only attributes allowed by the object class are contained in the entry
Schema checking also occurs when importing a database using LDIF. For more
information, refer to the Netscape Directory Server Administrator's Guide.
