• With the DRAC 5 web-based user interface. See "Configuring the DRAC 5
With Extended Schema Active Directory and Web-Based Interface" on
page 152.
• With the RACADM CLI tool. See "Configuring the DRAC 5 With
Extended Schema Active Directory and RACADM" on page 154.
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. 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. Companies can extend the Active Directory database by adding their own
unique Attributes and Classes to solve 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) 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 our
attributes and classes that are added into the directory service.
Dell extension is: dell
Dell base OID is: 1.2.840.113556.1.8000.1280
RAC LinkID range is:12070 to 12079
The Active Directory OID database maintained by Microsoft can be viewed
