Samba4 initially used the bind9 flat files way of running, but it didn't
and couldn't be made to work as an AD DC expects. This is why Samba4
moved to dlz, a lot needed to be done to get this to work, but it does
work as expected, ok there are a few minor problems, but I am sure these
will be fixed in time. I am not saying that the OP cannot use
flat-files, just that he is on his own there.

That is (in my opinion) a stupid way of doing things, every user with
the UID of 0 raises the potential for an attack, if you want to do this,
use sudo instead and yes sssd, AD and sudo will play nicely together.
Just because you think something is a good idea doesn't mean it is, but
nobody is stopping *you* doing things your way, just don't expect
sympathy if things go wrong.
