Currently I have a Web Service client on ruby using the soap4r gem and it is working fine(see script attached). But if the server uses NTLM authentication for the service i don't event get to execute the following line. @wsdl.create_rpc_driver() and it makes sense since it's waiting for the authentication hash on the request headers. I tried using wireshark to check my service using firefox and i could see the NTLM authentication hash on the request. Does anyone have used NTLM authentication for consuming secured web services. A little help will be appreciated. Attachments: http://www.ruby-forum.com/attachment/6175/ws_client.rb -- Posted via http://www.ruby-forum.com/.
