title: setting username and password in the http header for a SOAP request message using zeep (python)?
body: <p>How can you set the username and password in the http header for a SOAP request message using python's zeep? I believe that is why i am getting a connection refused error but cannot figure out where the http header details can be set. I even tried just running python -mzeep on the wsdl file (vs creating a client and calling a web service method) but it still cannot connect.</p>
