Correct. Squid would need a domain to verify the NTLM hash against.

All the proxy does is send an "Authorization Required" message to the
browser telling it what authentication methods (basic, digest, and/or NTLM)
are supported. How the browser gets the authentication credentials to send
back is entirely up to the browser - the proxy has no control over this.
