No, Samba doesn't produce sssd, so I know very little about sssd, not
that it matters :-)

There is a problem. Before Samba 4.8.0 , the smbd daemon (the
fileserver daemon) could contact AD directly, so you could use sssd.
When Samba 4.8.0 was released, smbd now can only contact AD via
winbind. Because sssd has its own version of some of the winbind libs,
you can no longer use sssd with Samba >= 4.8.0
Depending on how you run sssd (hopefully you are using rfc2307
attributes) you can easily change to winbind, if you are using id
mapping it will be a lot harder.
