Research direction
Start by running the Ubuntu 22.04 Docker command and the listed PSWSMan and Install-WSMan steps to reproduce the NTLM failure. Compare the image's OpenSSL configuration with the provided script, then verify that the image supports Enter-PSSession with Negotiate without manually editing /etc/ssl/openssl.cnf or restarting PowerShell.
