HTTP authentication error on git clone doesn't list LDAP/OAuth as potential causes
When authentication fails on the git CLI, when cloning via HTTPS, the authentication error shown lists 2FA as the reason why the request is rejected and that the user should use an access token instead. It doesn't however provide a clear example of how to do this.
I believe this error is also triggered when users are authenticated via LDAP on the installation. This error should more clearly explain that external auth services can also cause this error, if that is the case.
