Downgrading everything which was 2:4.3.11+dfsg-0ubuntu0.16.04.26 to 2:4.3.8+dfsg-0ubuntu1 worked for us. Here is the command we used:
apt-get install samba=2:4.3.8+dfsg-0ubuntu1 samba-common=2:4.3.8+dfsg-0ubuntu1 samba-common-bin=2:4.3.8+dfsg-0ubuntu1 libwbclient0=2:4.3.8+dfsg-0ubuntu1 samba-libs=2:4.3.8+dfsg-0ubuntu1 python-samba=2:4.3.8+dfsg-0ubuntu1 samba-dsdb-modules=2:4.3.8+dfsg-0ubuntu1 winbind=2:4.3.8+dfsg-0ubuntu1 samba-vfs-modules=2:4.3.8+dfsg-0ubuntu1 libsmbclient=2:4.3.8+dfsg-0ubuntu1
apt-mark hold samba
If you have other packages installed, you can list all in need of a downgrade with:
apt list | grep 2:4.3.11+dfsg-0ubuntu0.16.04.26 | grep installed
Looking forward to a new version of the security fix which does not disable LDAP.
