[Samba] Issues with mounting Samba shares after update

Actually it isn't part of AD at all.   We are using FreeIPA and Samba.  We
just finally figured this out with the help of some folks at Red Hat.  It
turned out there was a bug in one of the libraries that came along with
sssd (sssd-libwbclient I believe).  Their suggestion to use winbind and the
version of the same library that came with it seems to have solved our
problem instantly.  It appears that Red Hat is recommending not upgrading
to RHEL 7.4 until this bug is resolved.

However, a new file server we are setting up that appears to have the same
issue is not fixed by doing those same things making it a bit confusing.
We have compared config files between them, and they appear to be the same,
which makes it even more confusing.
