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.

Overview of Schema Extensions
Dell has extended the schema to include an Association, Device, and Privilege property. The Association property is used to link
together the users or groups with a specic set of privileges to one or more RAC devices. This model provides an administrator
maximum exibility over the dierent combinations of users, RAC privileges, and RAC devices on the network without much
complexity.
When there are two CMCs on the network that you want to integrate with Active Directory for authentication and authorization,
create at least one association object and one RAC device object for each CMC. You can create multiple association objects, and
each association object can be linked to as many users, groups of users, or RAC device objects as required. The users and RAC
device objects can be members of any domain in the enterprise.
However, each association object can be linked (or, may link users, groups of users, or RAC device objects) to only one privilege
object. This example allows an administrator to control each user’s privileges on specic CMCs.
The RAC device object is the link to RAC rmware for querying Active Directory for authentication and authorization. When a RAC is
added to the network, the administrator must congure the RAC 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 the RAC to at least one
association object for users to authenticate.
The following gure shows that the association object provides the connection that is needed for the authentication and
authorization.
NOTE: The RAC privilege object applies to DRAC 4, DRAC 5, and CMC.
You can create as many or as few association objects as required. However, you must create at least one Association Object, and you
must have one RAC device object for each RAC (CMC) on the network that you want to integrate with Active Directory.
Figure 8. Typical Setup for Active Directory Objects
The Association Object allows as many or as few users and/or groups and RAC Device Objects. However, the Association Object
only includes one Privilege Object per Association Object. The Association Object connects the Users who have Privileges on RACs
(CMCs).
Additionally, you can congure Active Directory objects in a single domain or in multiple domains. For example, you have two CMCs
(RAC1 and RAC2) and three existing Active Directory users (user1, user2, and user3). You want to give user1 and user2 an
