    We also had problems working around this in our Java code, so possibly not all product related.

     

    Right now we have two options.

     

    1)  Run a Burp instance as a local proxy, this intercepts the request from the client and takes responsibility for managing the connection/authentication to our internal web proxy.

     

    2) Configure an exception rule in the web proxy to non authenticate traffic bound for the target url for the relevant source node.

     

    Both worked, option 1 good enough for dev, option 2 will be taken forward in to environments.

Can you just attach full stacktrace of exception that you see?

Ok so if I put in my authentication details for the local web proxy (Preferences->Proxy Settings)

Do not authenticate preemptively (Prefrences->HTTP Settings )

Add my authentication details for the webservice endpoint (Auth (Basic) username+password).

      Hi thanks for the response.

       

      Its like this.

       

      SOAP UI | ---> | Web Proxy | ---> | WS Endpoint |

      ====================================

       

      To get past the Web Proxy I need to pass some credentials ( I think the proxy should work with either NTLM or Basic Auth)

       

      To access the WS Endpoint I need to pass some further credentials via HTTP Basic Auth. 

       

      I am specifying the credentials for the web proxy in Preferences -> Proxy Settings.  I have no option to specify the mechansim by which they are communicated.

       

      I am specifying the credential for the WS Endpoint in the Auth on the auth panel properties on the request, but I am choosing Basic not NTLM here - as this is (I assume) for the endpoint, not the proxy.

       

      I'm sorry if I'm not being clear / giving the right answers!

        Thank you for the details. Unfortunately, do not have such environment to try that out.
