note 51138 rejected from function.soap-soapclient-construct by betz

Note Submitter: phpsurf at ifrance dot com ---- I'm trying to call a web service from behind a proxy that requires NTLM authentication. I tried the usual proxy syntax, with the 4 param keys proxy_host, proxy_port, proxy_login, proxy_password. But it doesn't work. Whereas, when I'm home with no proxy, the same code works. Any idea ? Is that a limitation of the current implementation ? or is there any way to get it work ? Thanks
