Pretty much the same (CentOS7), including using sssd to join linux domain
members, as I don't have many and it was easier for me to understand (and
find documentation for) than winbind at the time.
As noted, the key to it is either building Samba4 from sources, or finding
somebody to do it for us (Thanks to the Tranquil.IT team) -- in both cases,
using Heimdal instead of MIT Kerberos.
And lastly, the Wing repo is down permanently. I found a note from the
site maintainer that he was discontinuing it a while back (it's in Japanese
and the link is in the archives somewhere).
