Sorry I replied to quickly; it should have been =E2=80=98--disable-authentication=E2=80=99. Why? Because here you=E2=80=99re trying to travel to a commit that=E2=80= =99s not part of the =E2=80=9Cauthenticated history=E2=80=9D=E2=80=94that is, it=E2=80=99= s not a descendant of the =E2=80=9Cintroductory commit=E2=80=9D, which is the first commit in history= starting from which the =E2=80=9Cauthentication invariant=E2=80=9D holds. Hopefully this is clearer; maybe? :-) Cheers, Ludo=E2=80=99.
