Extended Schema Overview
There are two ways to enable Extended Schema in Active Directory:
• Using the CMC Web interface. For instructions, see "Configuring CMC
With Extended Schema Active Directory and the Web Interface" on
page 264.
• Using the RACADM CLI tool. For instructions, see "Configuring CMC
With Extended Schema Active Directory and RACADM" on page 267.
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.
One example of a Class that is stored in the database is the user class.
User class attributes can include the user’s first name, last name,
phone number, and so on.
