[Pkg-samba-maint] Bug#739768: Confirm

[Jason Gunthorpe]

I am seeing this bug too, and I can confirm it is fixed in Ubuntu's
version. They have been shipping with this fix in trusty which works
in my environment. The latest patch from the upstream bug might be
better, but I haven't tried it.

For whatever reason upstream remains typically silent on the bug
report and proposed patch..

Here is the fix ubuntu is shipping:
