I've not tried cURL, but I have managed to get PHP to talk through an
NTLM proxy.
See my user note on
http://docs.php.net/manual/en/function.stream-context-get-default.php
Unfortunately, the link to an old site I had is dead.
But it was just some long windedness about http://ntlmaps.sourceforge.net/
Though you can use the Way Back When Machine (please make sure your ad
blockers are working - sorry!!!!) :
http://web.archive.org/web/20080427012158/http://rquadling.php1h.com/php_ntlm.php
If you go down this route, then also take a look at
http://web.archive.org/web/20080501043118/rquadling.php1h.com/python_ntlm.php
which is more on the same.
What this all means that you use the NTLMAPS proxy to do the NTLM
authentication for you.
But, hopefully, all of this isn't needed and that PHP now supports
NTLM authentication within cURL. Ideally, it should also be available
for regular stream contexts.
