Extended Schema Active Directory Overview

Using the extended schema solution requires the Active Directory schema extension.
Active Directory Schema Extensions
The Active Directory data is a distributed database of
rules that determine the type of data that can be added or included in the database. The user class is one example of a
class that is stored in the database. Some example 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
classes for specific requirements. Dell has extended the schema to include the necessary changes to support remote
management authentication and authorization using Active Directory.
attribute or class that is added to an existing Active Directory Schema must be defined with a unique ID. To
Each
maintain unique IDs across the industry, Microsoft maintains a database of Active Directory Object Identifiers (OIDs) so
that when companies add extensions to the schema, they can be guaranteed to be unique and not to conflict with each
other. To extend the schema in Microsoft's Active Directory, Dell received unique OIDs, unique name extensions, and
uniquely linked attribute IDs for the attributes and classes that are added into the directory service:
• Extension is: dell
• Base OID is: 1.2.840.113556.1.8000.1280
• RAC LinkID range is: 12070 to 12079
Overview of iDRAC7 Schema Extensions
Dell has extended the schema to include an
used to link together the users or groups with a specific set of privileges to one or more iDRAC7 devices. This model
provides an administrator maximum flexibility over the different combinations of users, iDRAC7 privileges, and iDRAC7
devices on the network without much complexity.
For each physical iDRAC7 device on the network that you want to integrate with Active Directory for authentication and
authorization, create at least one association object and one iDRAC7 device object. You can create multiple association
objects, and each association object can be linked to as many users, groups of users, or iDRAC7 device objects as
required. The users and iDRAC7 user groups can be members of any domain in the enterprise.
However, each association object can be linked (or, may link users, groups of users, or iDRAC7 device objects) to only
one privilege object. This example allows an administrator to control each user's privileges on specific iDRAC7 devices.
iDRAC7 device object is the link to iDRAC7 firmware for querying Active Directory for authentication and authorization.
When iDRAC7 is added to the network, the administrator must configure iDRAC7 and its device object with its Active
Directory name so that users can perform authentication and authorization with Active Directory. Additionally, the
administrator must add iDRAC7 to at least one association object for users to authenticate.

authorization.
