Users can be assigned DCUI access privileges explicitly via the DCUI Access advanced configuration option. The option has DCUI.Access as the key, and a comma-separated list of ESXi users as the value. Users in the list which can access the DCUI at any time, even if these users are not administrators (Admin role), and even when the host is in lockdown mode.
