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 specific set of privileges to one or more RAC devices. This model provides an administrator maximum flexibility
over the different 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 specific CMCs.
The RAC device object is the link to RAC firmware for querying Active Directory for authentication and authorization. When a RAC is
added to the network, the administrator must configure 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.
NOTE: The RAC privilege object applies to 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.
The Association Object allows as many or as few users and/or groups as well as 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 configure 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 administrator privilege
to both CMCs and give user3 a login privilege to the RAC2 card.
When adding Universal Groups from separate domains, create an Association Object with Universal Scope. The Default Association
objects created by the Dell Schema Extender Utility are Domain Local Groups and does not work with Universal Groups from other
domains.
To configure the objects for the single domain scenario:
1. Create two Association Objects.
2. Create two RAC Device Objects, RAC1 and RAC2, to represent the two CMCs.
3. Create two Privilege Objects, Priv1 and Priv2, in which Priv1 has all privileges (administrator) and Priv2 has login privilege.
4. Group user1 and user2 into Group1.
5. Add Group1 as Members in Association Object 1 (A01), Priv1 as Privilege Objects in A01, and RAC1, RAC2 as RAC Devices in A01.
6. Add User3 as Members in Association Object 2 (A02), Priv2 as Privilege Objects in A02, and RAC2 as RAC Devices in A02.
To configure the objects for the multiple domain scenario:
1. Make that the domain forest function is in Native or Windows 2003 mode.
2. Create two Association Objects, A01 (of Universal scope) and A02, in any domain. The figure Setting Up Active Directory Objects in
Multiple Domains shows the objects in Domain2.
3. Create two RAC Device Objects, RAC1 and RAC2, to represent the two CMCs.
4. Create two Privilege Objects, Priv1 and Priv2, in which Priv1 has all privileges (administrator) and Priv2 has login privilege.
5. Group user1 and user2 into Group1. The group scope of Group1 must be Universal.
6. Add Group1 as Members in Association Object 1 (A01), Priv1 as Privilege Objects in A01, and RAC1, RAC2 as RAC Devices in A01.
7. Add User3 as Members in Association Object 2 (A02), Priv2 as Privilege Objects in A02, and RAC2 as RAC Devices in A02.
Configuring Extended Schema Active Directory
To configure Active Directory to access CMC:
1. Extend the Active Directory schema.
2. Extend the Active Directory Users and Computers Snap-in.
3. Add CMC users and their privileges to Active Directory.
4. Enable SSL on each of your domain controllers.
5. Configure CMC Active Directory properties using CMC web interface or RACADM.
