OWA (Outlook Web Access) with urllib2

[Pascal]

Hello,

I want to acces my OWA (Outlook Web Acces - http Exchange interface)
server with urllib2 but, when I try, I've always a 401 http error.
Can someone help me (and us)?

Thanks.


here's my pyscript:
( Python 2.3.3 (#1, Apr  6 2004, 01:47:39) - [GCC 3.3.3 (SuSE Linux)]
on linux2 )
************************************************************************
#! /usr/bin/python


import urllib2


# set authentification
auth = urllib2.HTTPBasicAuthHandler()
auth.add_password('owa.mydomain', 'http://owa.mydomain/',
'**USERNAME**', '**PASSWORD**')


# don't use proxy
prox = urllib2.ProxyHandler({})


# installation
opener = urllib2.build_opener(prox, auth)
urllib2.install_opener(opener)


# start
url = urllib2.urlopen('http://owa.mydomain/exchange/')
print url.readlines()

here's the traceback:
