The following is a very basic, contrived example which assumes the following

1. That you have already enabled Active Directory authentication ( see KB https://knowledge.broadcom.com/external/article?articleId=171932 )
2. A domain with the following configuration:

• • Domain Name: yeti.local
  • Users physically reside within a Container object at:
    • CN=Users,DC=yeti,DC=local
  • Security Group "DLP Admins" created in AD at the following path:
    • CN=DLP Admins,OU=DLP Groups,OU=User Groups,DC=yeti,DC=local

1. Add a Directory Connection under System -> Settings -> Directory Connections and click Test Connection, as shown below (be sure to use the correct port for your AD):
2. Navigate to System -> Users ->  Data Sources
3. Click Add -> AD Logins Source, named "AD User Logins" as shown below and click Submit
   
4. Navigate to System -> Users -> User Groups
5. Click Create New Group, name it "DLP Admins", and configure the highlighted fields as shown below and click Save
   
   
6. Navigate to System -> Login Management -> Roles
7. Click Add Role, name it DLP Admins and select Server Administration under the User Privileges section
8. Move to the Users & Groups tab and select User Groups -> DLP Admins and click Save
9. Navigate to System -> Users -> Data Sources
10. Select the checkbox next to the AD User Logins data source and click the Import button in the toolbar
11. In the manager logs under C:\ProgramData\Symantec\DataLossPrevention\EnforceServer\<ver>\logs\tomcat\ directory, in the current "localhost.<currentdate>.log" file, with FINE level logging enabled, you should see entries similar to the following:

The imported users will now be added to the DLP Users (in the ProtectUser table in the database). You can view them from the console at System -> Login Management -> DLP Users. At this point you can log into the console as either of these users, with Server Management privileges.
