Hello Milan, yes, of course, that was also my plan, I just needed to make a final touch. Originally, I wanted to ask in libsoup mailing list if someone would take a look. But since you proposed to file it as a bug report, I did. I created a new bug report: Bug 793613 - NTLMv2 responses support https://bugzilla.gnome.org/show_bug.cgi?id=793613
