Description |

When adding ESXi hosts to Active Directory, all user/group accounts assigned to the Active Directory group "ESX Admins" will have full administrative access to the host. If this group is not controlled or known to the system administrators, it may be used for inappropriate access to the host. Therefore, the default group must be changed to a site-specific Active Directory group and membership must be severely restricted. |
