HP Directory Services Schema Information Booklet

Abstract

This guide provides the Directory Services schema for HP management products. This

schema works on all LDAP v3 compliant directories. The tables below contain class,

category and attribute definitions relating to remote management.

Audience Assumptions

This guide is for the person who installs, administers, and troubleshoots servers. HP assumes

you are qualified in the servicing of computer equipment and trained in recognizing hazards

in products with hazardous energy levels.

Schema Considerations

Naming Conventions and Registry

HP schema extensions follow the LDAP naming convention, which includes meaningful

names with initial lowercase and interior word initial capitialization. Names are constrained

to 30 characters to improve interoperability. All HP schema extensions associated with

directory-enabled management are prefixed with “hpq.” This prefix has been registered and

reserved for HP schema extensions with Microsoft and Novell, and follows the LDAP

convention of prefixing a short enterprise-specific moniker, such as a stock ticker symbol.

The LDAP Object IDentifiers (OIDs) used for directory-enabled management are assigned by

an HP internal authority and follow standard numbering conventions. The OIDs are assigned

from a subbranch of an ISO assigned OID tree belonging to HP, 1.3.6.1.4.1.232.

Replication

Attributes and classes used with HP directory-enabled management products do not have any

extra replication requirements. No indexes, filtered replicas, global catalog changes, or

schema replication settings are required for the products to function properly. Attributes and

objects within the directory service are only updated by administrative use of the

management snapins or other utilities. Replication of the HP directory-enabled attributes and

objects will be infrequent because the attributes and objects are not changed outside of the

use of the management snap-ins or utilities.

Schema Updates

HP schema extensions for directory-enabled management products include classes and

attributes that store information required to manage those products. Extensions are used in

favor of existing attributes so that the schema will be easier to use and understand. HP

understands that extending the schema requires caution and will offer customers new schema

extensions as infrequently as possible.
