Can't get around HTTP/401 response using SUDS

SUDS version 0.4 pn x86_64 Python 2.7

I'm having a bear of a time getting HTTP Basic Authentication to work
for a SOAP request via suds. Also using an HTTP proxy server.

In WireShark I just see a request -
GET http://...../services/services/JobService-0.0.1?wsdl HTTP/1.1
Accept-Encoding: identity
Host: .......
Connection: close
User-Agent: Python-urllib/2.7

This doesn't contain any authentication credentials so the response is
HTTP/401, and the client doesn't retry with credentials. The response
does come from the remote as I can see there is a WWW-Authenticate
header and it is from an Apache Tomcat server - so it makes it through
the proxy server.

Code
================
url = 'http://....../services/services/JobService-0.0.1?wsdl'
proxy = urllib2.ProxyHandler({'http': 'http://.....:3128'})
transport = suds.transport.http.HttpAuthenticated()
transport.urlopener = urllib2.build_opener(proxy)
client = suds.client.Client(url, transport=transport,
username='******', password='********')
.....

I've tried the above as well as the method described at
<http://blogs.oucs.ox.ac.uk/inapickle/2011/05/14/exchange-web-services-suds-and-python/> It has the same problem.
