I'm working with IBM on this, trying to convince them to debug their
bindsock binary. The initial hurdle, which I may or may not be able to
overcome, is the boilerplate "Ubuntu is not a supported OS." I've
offered to send them a virtual machine with the problem already present,
we'll see how this goes.

If this re-appears again in a new kernel line (and you've come here from a google search from the future in your DeLorean, complete with Flux Capacitor), I also want to share another workaround I've found: build & install the vanilla kernel. I've tried it and it works. Here's a tutorial:

Bug description:
  Starting  with kernels  3.2.0-64 and 3.13.0-29  Something has changed
  to once again that prevents IBM Domino's
  "/opt/ibm/domino/notes/latest/linux/bindsock" binary that runs as root
  (setuid) to get ports lower than 1024 for it's LDAP, SMTP, IMAP, POP3,
  and HTTP processes.

  The Domino server reports  the following: :
    "Listener failure: 'bindsock' is missing, not executable, not owned by root, not setuid root or user needs net_privaddr privilege."

  This is the same behaviour that was reported and subsequently
  corrected in Bug # 1269053
