You must specify Group settings in the AD module before you can import groups from the AD server. See AD Group Settings.
After making a change to imported groups or users, you must synchronize the AD user groups you changed so that the imported groups are mapped to the appropriate groups on AD and synchronize all AD modules to synchronize all groups and users in all modules. See Synchronize All User Groups with AD and Synchronize All AD Modules.
You can import nested groups from AD.
Note: Make sure that you have configured the CC-SG DNS and Domain Suffix in Configuration Manager before attempting to import AD user groups. See Advanced Administration.
To import AD user groups:
Tip: To check that the group imported properly and to view the privileges of the group just imported, click the Users tab, then select the imported group to open the User Group Profile screen. Verify the information in the Privileges and Device/Node Policies tab. Click the Active Directory Associations tab to view information on the AD module associated with the user group.
