This has been repeated a few times, - do not use - but there's no conclusive reason
given (to me it looks more like "there are bugs in samba which prevent doing this" -
it's a good reason already but it's not given).

Here, I've a domain which is supposed to go into production,
replacing an old NT4-style domain. There's just one server
in that office. I created a virtual machine for new samba,
set up the DC on it, and I need to verify if it works. The
most natural thing to do - to me anyway, since I'm not concerned
yet about all the disadvantages listed on that WIKI page, -
for now it is just a test - when there are just two machines on
the domain, the Samba DC and a Win10 client - is to try to access
a file share from win on the DC. Because if I install a new
VM with a file server on it, I can screw samba on it when
joining it to this new domain already, so if win doesn't
work with this other file server, it might be due to its own
configuration issue. It is the most natural thing to do to
verify if win works with the DC first, and install new servers
only after it's done. In other words, it's quite natural to
do one thing after another, not all together at once.
Besides, for a new file server, I'll need to install yet
another VM just for testing, which is a clear and obvious
I'm not arguing here. I'm outlining the "why". And it does
not look like I'm alone there, -- it SEEMS like a very natural
thing to use the DC as a fileserver despite all the "disadvantages"
listed. Because even just one reason: a need to install a VM -
might be enough to make this idea (running a DC in a VM) to be
rejected entirely. (It is not a prob for me, but even for me
it required quite some prior research and especially completely
changing network configuration on a remote server without remote
console access - this *is* not easy).
For this reason, maybe it's a good idea to review the issues which
do pop up when one is trying to use Samba DC as a file server, and
document the list, maybe fix some of the things in there (like the
explorer crashing - it is well-known bug,
https://bugzilla.samba.org/show_bug.cgi?id=14213 ). With this understanding
it will be much easier for anyone to see which actual problems are
expected and whenever he is able to deal with them, and if it really
is worth to install a VM.
