Error: "Authentication failure" when trying to log into Symantec Endpoint Protection Manager console with an additional Admin account
When you login to the Symantec Endpoint Protection Manager console using the Default Administrator you can login successfully However if you create a new Admin and try to login you get an error "Authentication failure"
Reseting the password for the additional Admin account also does not help.
In the SEPM Console go to the Admin tab
Check if more than one Domain is present, if Yes then add the admin account to all the Domains
Also while logging in to SEPM, you may select the correct Domain by clicking on the button "Options"
You should be able to login successfully.
