Dell iDRAC 8 User Manual page 137

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 iDRAC Device Object for each iDRAC device on the network that you want to integrate with Active Directory
for Authentication and Authorization with iDRAC.
The Association Object allows for as many or as few users and/or groups as well as iDRAC Device Objects. However, the
Association Object only includes one Privilege Object per Association Object. The Association Object connects the Users who have
Privileges on iDRAC devices.
The Dell extension to the ADUC MMC Snap-in only allows associating the Privilege Object and iDRAC Objects from the same
domain with the Association Object. The Dell extension does not allow a group or an iDRAC object from other domains to be added
as a product member of the Association Object.
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.
Users, user groups, or nested user groups from any domain can be added into the Association Object. Extended Schema solutions
support any user group type and any user group nesting across multiple domains allowed by Microsoft Active Directory.
Accumulating privileges using Extended Schema
The Extended Schema Authentication mechanism supports Privilege Accumulation from different privilege objects associated with
the same user through different Association Objects. In other words, Extended Schema Authentication accumulates privileges to
allow the user the super set of all assigned privileges corresponding to the different privilege objects associated with the same user.
The following figure provides an example of accumulating privileges using Extended Schema.
Figure 3. Privilege accumulation for a user
The figure shows two Association Objects—A01 and A02. User1 is associated to iDRAC2 through both association objects.
Extended Schema Authentication accumulates privileges to allow the user the maximum set of privileges possible considering the
assigned privileges of the different privilege objects associated to the same user.
In this example, User1 has both Priv1 and Priv2 privileges on iDRAC2. User1 has Priv1 privileges on iDRAC1 only. User2 has Priv1
privileges on both iDRAC1 and iDRAC2. In addition, this figure shows that User1 can be in a different domain and can be a member
of a group.
