NS8 as a Fileserver with external AD?

I still need to setup a NS8 with external AD (MS Active Directory) and act as a Fileserver…

ATM NS8 cannot do this job, Is this feature on the Roadmap?

Another Idea would be to establishing a trust relationship btw a NS8 with Samba-AD and a MS Domain Controller.

Example: UCS Samba/AD: How to establish trust with native Microsoft Active Directory domains

INFO: Windows Integration Guide

Does someone else have this UseCase and need a Solution?
