•
When adding new schema elements, all attributes need to be defined before
they can be used in an object class. You can define attributes and object classes
in the same schema file.
•
Each custom attribute or object class you create should be defined in only one
schema file. This prevents the server from overriding any previous definitions
when it loads the most recently created schema (as the server loads the schema
in numerical order first, then alphabetical order).
Maintaining Consistent Schema
A consistent schema within Directory Server aids LDAP client applications in
locating directory entries. If you use an inconsistent schema, then it becomes very
difficult to locate information in your directory tree efficiently.
Inconsistent schema use different attributes or formats to store the same
information. You can maintain schema consistency in the following ways:
•
Use schema checking to ensure attributes and object classes conform to the
schema rules.
•
Select and apply a consistent data format.
