Research direction

Start by locating the sshd configuration option parser and comparing its supported options with the GSSAPIAuthentication handling in upstream OpenSSH. The report provides a reproduction using sshd.exe and a minimal expected behavior, but does not name source files or tests. Done means sshd.exe accepts GSSAPIAuthentication yes in its configuration without the reported error.
