Consistent data assists LDAP client applications in locating directory entries. For each type of information that is stored in the directory, select the required object classes and attributes to support that information. Always use the same object classes and attributes. If you use schema objects inconsistently, it is difficult to locate information.
You can maintain schema consistency in the following ways:
Use schema checking to ensure that attributes and object classes conform to the schema rules.
For more information about schema checking, see Chapter 11, Directory Server Schema, in Sun Java System Directory Server Enterprise Edition 6.1 Administration Guide.
Select and apply a consistent data format.
The LDAP schema allows you to place any data on any attribute value. However, you should store data consistently in the DIT by selecting a format appropriate for your LDAP client applications and directory users. With the LDAP protocol and Directory Server, you must represent data using the data formats specified in RFC 4517.
