146 Using the CMC With Microsoft Active Directory
Extended Schema Overview
There are two ways to enable Extended Schema Active Directory:
• Using the CMC Web interface. For instructions, see "Configuring the
CMC With Extended Schema Active Directory and the Web Interface" on
page 161.
• Using the RACADM CLI tool. For instructions, see "Configuring the
CMC With Extended Schema Active Directory and RACADM" on
page 163.
Active Directory Schema Extensions
The Active Directory data is a distributed database of Attributes and Classes.
The Active Directory schema includes the rules that determine the type of
data that can be added or included in the database.
One example of a Class that is stored in the database is the user class. User
class attributes can include the user’s first name, last name, phone number,
and so on.
You can extend the Active Directory database by adding your own unique
Attributes and Classes to address your company’s environment-specific
needs. Dell has extended the schema to include the necessary changes to
support remote management Authentication and Authorization.
Each Attribute or Class that is added to an existing Active Directory Schema
must be defined with a unique ID. To maintain unique IDs across the
industry, Microsoft maintains a database of Active Directory Object
Identifiers (OIDs). To extend the schema in Microsoft's Active Directory,
Dell established unique OIDs, unique name extensions, and uniquely linked
attribute IDs for Dell-specific Attributes and Classes:
Dell extension: dell
Dell base OID: 1.2.840.113556.1.8000.1280
RAC LinkID range: 12070–2079
Overview of the RAC Schema Extensions
Dell provides a group of properties that you can configure. The Dell-extended
schema include Association, Device, and Privilege properties.
