Looks like I need todo more search than to develop solutions. ^^ The 8th patch version from charlieio@outlook.com looks better than my implementation. Thanks and bye, Silvio

Please note that this has been addressed for NTLM in https://github.com/curl/curl/pull/3345 and the gssapi problem is probably worked around by https://github.com/curl/curl/pull/3349. Both patches were backported to the cURL version included in Git for Windows v2.20.0. > > Signed-off-by: Silvio Fricke <silvio.fricke@gmail.com> > > This looks very similar to [1] which is already in Junio's "next" > branch (although not yet in a released version of Git). Small correction: it is in Git *for Windows* v2.20.0, so in a manner of speaking it *is* in a released version of Git. The reason: even if we included the NTLM/Kerberos patches in Git for Windows, there might be other scenarios where neither of those patches catch.

HTTP has several protocol versions. By default, libcurl is using HTTP/2 today and check if the remote can use this protocol variant and fall back to a previous version if not. Under rare conditions it is needed to switch the used protocol version to fight again wrongly implemented authorization mechanism like ntlm with gssapi on remote side. Signed-off-by: Silvio Fricke <silvio.fricke@gmail.com> --- Notes: I hit a problem with a libcurl (Namely [this bug]). This bug looks like never get fixed and to just-use-git from my commandline I don't want compile a own libcurl with disabled gssapi or/and http/2.
