It's a best practice to enable this option with service accounts and to use strong passwords. The practice of using domain Administrator accounts to run services and tasks on workstations creates a significant risk of credential theft attacks and, therefore, should be replaced with alternative means to run scheduled tasks or services. An organization suspecting domain compromise of the KRBTGT account should consider the use of professional incident response services. Then stage the deployment in a manner that allows for a rollback of the change if technical issues occur. Use accounts that have been granted sensitive administrator rights only to administer domain data and domain controllers. User identities can be added to Tableau Server in the server UI, using tabcmd Commands, or using the REST API. The SIDs that are related to each of the default local accounts in Active Directory are described in the next sections. The Windows Biometric Framework feature is installed using Server Manager.
