--- Comment #9 from Zhenya Zenitur@yandex.ru --- Hans, I see you're disable KRB5 1.6 totally. Hovewer KRB5 1.6 is working with Wine. The only one thing that doesn't working is authorization support added in Wine 3.1.
Tale a look on this fix of an old GnuTLS: https://bugs.winehq.org/show_bug.cgi?id=43971. A developer didn't disable all GnuTLS, but only bcrypt authorization was disabled.
