Now I have checked the ubuntu repos. The patch is applied to:

samba (2:4.3.11+dfsg-0ubuntu0.14.04.14) trusty-security
samba (2:4.3.11+dfsg-0ubuntu0.16.04.13) xenial-security
samba (2:4.6.7+dfsg-1ubuntu3.2) artful-security

So you have one (easy) choice. Download the source package from artful-
security and build it on xenial. This brings you to a supported samba 
release.
