Creating accounts for the Administration Server services on a failover cluster
By default, the installer automatically creates non-privileged accounts for services of Administration Server. This behavior is the most convenient for Administration Server installation on an ordinary device.
However, installation of Administration Server on a failover cluster requires a different scenario:
Create non-privileged domain accounts for services of Administration Server and make them members of a global domain security group named KLAdmins.
In the Administration Server Installer, specify the domain accounts that have been created for the services.
