Yes, 4.5.x is still supported, but, when 4.7.0 comes out, it will move
to security fixes only. I would factor in upgrading Samba on a
regular basis, there have been reports of problems if you go a long
time between upgrades.

You have to use Windows ACLs on a DC, so things like 'write list' and
'valid users' don't work, see here:


I think that 20 shares is a bit over the top for a DC, it sort of
points at you having a lot of users and computers, you will probably be
better of using a separate fileserver instead.
