Please either wait for beta7 (very soon) or use GIT master.  I've
finally fixed a lot of issues here. 

It won't really matter, but you can do it in stages if you like.

Yes.

If you only have a sysvol share, then running:

samba-tool ntacl sysvolreset

after configuring it back to the default file server (s3fs) will set the
POSIX ACLs you need.

Honestly, I don't think we changed anything that this will matter for
since beta3, so don't worry too much.

That should be OK.
