Python Digest authentication against MS MapPoint

[trapeze.jsg at gmail.com]

Hi.

Is there anybody who have tried to use python to access Microsofts
MapPoint soap services? I am trying hard but I have run into a big
thick wall called md5 digest authentication. The MapPoint service uses
rfc2617 to authenticate the user. I have a working account for this
which works using C# dotnet and Borland Delphi 6.0. When I try to
authenticate using python it fail.

Here is what I do to provoke the rfc2617 challenge:
import urllib2
r=urllib2.Request('http://findv3.staging.mappoint.net/Find-30/FindService.asmx')
auth_handler = urllib2.HTTPDigestAuthHandler()
auth_handler.add_password('MapPoint','findv3.staging.mappoint.net','user','passwd')
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)
urllib2.urlopen(r)

I can see using ethereal to monitor the network trafic, that urllib2
resonds to the challenge in a way that seems reasenable, but
authorization is not granted:
