Configuring MMC for Active Directory Services 
Use
The MMC can be configured so that its structure and some of the information it presents are taken directly from the Windows 2000 Active Directory. The Active Directory is an extensive hierarchical inventory of all the objects available in a network. Special services make it possible to access and manipulate the information stored in the directory whenever required.
Configuring the MMC on the basis of the Active directory has the following advantages:

The MMC can be configured to access LDAP directories other than the Active Directory. In this case, additional instructions have to be observed.
Prerequisites
The R/3 System must be configured appropriately to support LDAP services.
Procedure
The Add/Remove Snap-In dialog box opens.
The General Settings dialog box opens.
For Options
Select Query LDAP Directory for R/3 Instances.
For Auto Refreshment
Enter the periods in which you want system information in the MMC to be updated automatically.
For Options
Select Expert user mode if you want to access more detailed system information later when you start working with the R/3 snap in.
Deselect Always show local R/3 instances. These are automatically displayed in the MMC when the configuration is complete.
The LDAP Directory Connection dialog box opens.
