It seems winbind is not installed, while it is root@a183f106f3ef:/# dpkg -l| grep -i "winbind" ii libwbclient0:amd64 2:4.3.11+dfsg-0ubuntu0.14.04.6 amd64 Samba winbind client library
Unfortunately I don't think I'll be able to help you, since I am not using this image anymore and thus can't really test it.
Your issue might be caused by some update that happened to Samba4, see this message thread, but that is just a guess.
