Comment:

 It appears as though our patch continues to disable NTLMv2 auth. The
 commit for the bug in question only adds packet parsing and construction
 for NTLMv2, and our patch disables it before we even get to that point.
 https://hg.mozilla.org/mozilla-central/rev/f09bfc814171

 Related, the patch to prevent info disclosures still has not landed:
 https://bugzilla.mozilla.org/show_bug.cgi?id=1046421.

 My recommendation is that we should always leave NTLM off. I am deeply
 worried about stuff like #11055 and Windows-specific leaks biting us.
 Closing this.
