You want to use Active Directory accounts to log in to Symantec Endpoint Protection Manager (SEPM).
To configure an SEPM administrator account to use Active Directory authentication, both Step A and Step B are required.
Note: Repeat Step B for every account which needs to use Active Directory authentication.
Testing the newly created account:
Do not use the built-in SEPM System administrator account called: admin when setting up Active Directory Authentication, doing so can prevent logon access to SEPM with "Authentication Failure" error. Lockout issues can occur when changing the Active Directory account, upgrading Active Directory, changing Active Directory mode, and when removing SEPM(s) as a replication partner.
SEPM Active Directory Authentication is only supported for an administrator account that has been created in SEPM by clicking "Add an administrator."
Note: The SEPM admininistrator name you created/added is taken from SEPM database while the password is taken from Active Directory.
