Build In Local ID Question

Hi guys,

My customer currently uses CyberArk to do ID management. For Nutanix clusters, I know there are two build-in local IDs: One is admin which could access from Web GUI and CLI, another is nutanix which could access from CLI.

I want to know:

1. Any references which other cases use CyberArk to do ID management for Nutanix IDs?
2. admin/nutanix could be disabled?
3. If could not be disabled, could these IDs be managed by CyberArk?

Thanks!
