Extension Unavailability while using RBAC (1904.1)

Hi,

I have not been able to use or see extensions such as Active Directory, DHCP  and DNS while using RBAC. Is anyone else experiencing this? I can see the account is in limited access mode, but does this mean extensions can’t be used?

If I sign into WAC using a domain or local administrator account, I am able to view, add and use extensions.

Thanks
