Unable to load shared Lib "git2-106a5f2" or one of its dependencies & "Negotiate" authentication is not supported

Reproduction steps

Our .net 6 app uses LibGit2Sharp 0.26.2 version . Our git is in Bitbucket which accepts Kerberos via SPNEGO. It all works fine in our windows environment. when we do dotnet publish ...... -r linux-x64 , I see that the 'git2-106a5f2' is also copied. A container is created with Linux/ubi7 to run the app, where we get the Unable to load shared Lib "git2-106a5f2" or one of its dependencies

Later I upgraded it to 0.27.0-preview-0182 which fixed Unable to load shared Lib "git2-106a5f2". However, it start throwing "Negotiate" authentication is not supported when Repo.Clone is called with CloneOptions.

CloneOptions is given a new DefaultCredentials() call back , to work with SPNEGO.

Version of LibGit2Sharp (release number or SHA1)

LibGit2Sharp 0.26.2 - Unable to load shared Lib "git2-106a5f2"

0.27.0-preview-0182 - "Negotiate" authentication is not supported

Operating system(s) tested; .NET runtime tested

.net 6

Start with the reproduction steps using LibGit2Sharp 0.26.2 and 0.27.0-preview-0182 in the described .NET 6 Linux container. Inspect the CloneOptions callback using DefaultCredentials and compare the native library-loading and Negotiate failures across those versions. Done means the relevant failure is reproducible and its supported resolution or limitation is documented.
