Description
Prior to NSX-T 3.1 and earlier, there are three local accounts: root, admin, and audit. These local accounts could not be disabled and no additional accounts could be created. Starting in NSX-T 3.1.1, there are two additional guest user accounts: guestuser1 and guestuser2. The local accounts for audit and guest users are disabled by default, but can be deactivated once active; however, admin and root accounts cannot be disabled. These accounts should remain disabled and unique non-local user accounts should be used instead.
