Viewing The Default Directory Schema; Matching Data To Schema Elements - Red Hat DIRECTORY SERVER 8.1 - DEPLOYMENT Deployment Manual

3.3.1. Viewing the Default Directory Schema

The default directory schema is stored in /etc/dirsrv/schema/.
This directory contains all of the common schema for the Directory Server. The LDAPv3 standard user
and organization schema can be found in the 00core.ldif file. The configuration schema used by
earlier versions of the directory can be found in the 50ns-directory.ldif file.
WARNING
Do not modify the default directory schema.
For more information about each object class and attribute found in directory, see the Directory
Server Schema Reference. For more information about the schema files and directory configuration
attributes, see the Directory Server Configuration, Command, and File Reference.

3.3.2. Matching Data to Schema Elements

The data identified in the site survey now needs to be mapped to the existing directory schema. This
process involves the following steps:
1. Identify the type of object the data describes.
Select an object that best matches the data described in the site survey. Sometimes, a piece of
data can describe multiple objects. Determine if the difference needs to be noted in the directory
schema.
For example, a telephone number can describe an employee's telephone number and a
conference room's telephone number. Determine if these different sorts of data need to be
considered different objects in the directory schema.
2. Select a similar object class from the default schema.
It is best to use the common object classes, such as groups, people, and organizations.
3. Select a similar attribute from the matching object class.
Select an attribute from within the matching object class that best matches the piece of data
identified in the site survey.
4. Identify the unmatched data from the site survey.
If there are some pieces of data that do not match the object classes and attributes defined by the
default directory schema, customize the schema. See
more information.
