sssd is used for authentication and until recently this was all it could
do for AD, winbind on the other hand does authentication and a lot more.
So if you do not run the winbind daemon, samba can get the
authentication from sssd.

there must be some difference between how samba does the join and how
adcli does it.

Yes it works because instead of getting authentication from winbind, it
gets it from sssd.

This is most probably a dns problem, try comparing the network files
between the two versions, though the problem is usually the opposite way
round.
