SOAPUI. Accessing a basic authentication webservice through companies web proxy

Hi.  I'm on SOAPUI v5.2.1.

 

I need to call an internet exposed service from inside my companies network.  To get out to the internet I need to go through the companies web proxy.  Windows domain\user credentials allow this.  The target WebService expects basic authentication credentials.

 

I configure Preferences->Proxy Settings (pointing at the proxies IP, on port 80, specifying by domain\user\password)

 

In the HTTP header I see a Authorization : Basic : elements added with a base64 encoded string.

 

I can hit the target endpoint - but get a noat authorised error (not suprisingly).

 

NOW:

 

I add the basic authentication details to my request -> Authorization Basic, username/password...

 

I now get an Error getting response;java.lang.NullPointerException...

 

I don't see anything in the requests http headers to do with authorization at all.

 

SO:

 

Any tips for setting up access to a basic auth protected http web service when accessing via a web proxy that also needs to be authenticated to?

 

Thanks

Jamie

    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?

      Good shout Rao.  I'll do this first thing tomorrow morning.

      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).
