I still can do this web service right so I ask for some help please. I got the wsdl and make a client with wsdl2ruby.rb. When I run ruby -d client I got the following output: = Request ! CONNECT TO XXX.XXX.XXX.XXX:80 ! CONNECTION ESTABLISHED POST /DataFeed/DataFeed.asmx HTTP/1.1 SOAPAction: “[Bing](http://tempuri.org/ReturnLastPriceList)” Content-Type: text/xml; charset=utf-8 User-Agent: SOAP4R/1.5.5 (http-access2.rb/1.1.1.1, ruby 1.8.5 (2006-12-25) [i386 -mswin32]) Date: Mon Feb 19 20:41:00 +0100 2007 Content-Length: 339 Host: XXX.XXX.XXX.XXX \ \ env:Body ZVDPR\ \ \ = Response HTTP/1.1 401 Access Denied Server: Microsoft-IIS/5.0 Date: Mon, 19 Feb 2007 19:40:40 GMT WWW-Authenticate: Negotiate WWW-Authenticate: NTLM Connection: close Content-Length: 4431 Content-Type: text/html … I have this web service client in C# but I would like to make it on ruby. I ask you for some help, example or a hint. Thanks in advance. dima ---

Somewhere (ruby’s tracker? svn?) there’s a patch that adds ntlm auth support for net/http. Perhaps you could try that. (see ruby-core:10341) ---

If your client will only run on Windows systems, you could try the patch below[1], which supports NTLM authentication; otherwise, consider using client IP address, or some application-level control, for authentication, as NTLM is a proprietary Microsoft auth mechanism, and will block most client platforms from being able to access your service. -Lennon 1 - [http://rubyforge.org/tracker/index.php?func=detail&aid=5177&group\_id=426&atid=1700](http://rubyforge.org/tracker/index.php?func=detail&aid=5177&group_id=426&atid=1700) ---

Thank you for you swift response. I guessed that the problem is with authentication and with NTLM. Unfortunately I do not know what that is all about. It will be extremely helpful if you have some kind of sample code. dima ---

I had to use the 3rd party web service that will not change by mine request. The rubyntlm has a working http example, throughout socket connection, that I will explore and try to combine with soap4r. I will share the results of this quest. dima ---

My suggestion would be to talk to your server administrator, and see about turning off the NTLM auth – as I said, it’s a proprietary spec used almost exclusively Microsoft-only shops, and is going to cause you all kinds of problems when trying to access your web service from other client platforms. (Plus, anything based on NTLM auth is inherently insecure, as it’s rather easy to crack the LanMan hash format.) If you really need HTTP authentication, stick to the basics: HTTP- Digest, optionally protected by HTTPS if you need transport-level encryption, too. Take a look here for some examples of using standard HTTP authentication with a ruby SOAP client: > **[SOAP + Basic Authentication in Ruby](http://chrismcmahonsblog.blogspot.com/2006/03/soap-basic-authentication-in-ruby.html)** > > Do you need to do SOAP in Ruby? First of all, install the latest version of Ruby you can stand. (I'm using this one . What the heck. I'... Hope that helps, -rcoder
