Hey everybody,

I'm having a little problem with urllib2 and Basic HTTP authentication.

I have the following code:

auth = urllib2.HTTPPasswordMgrWithDefaultRealm()
auth.add_password(None, 'https://webmail.osg-erasmus.nl/oneNet/NetStorage/',
user, password)
authhandler = urllib2.HTTPBasicAuthHandler(auth)

opener = urllib2.build_opener(auth)
opener.addheaders = [('User-agent', 'Mozilla/5.0 Something/1.0')]

try:
        return
self.opener.open('https://webmail.osg-erasmus.nl/oneNet/NetStorage/')
except urllib2.HTTPError, e:
        print e.code
        print e.headers

This however does not allow me to authenticate. I keep getting back a 401:

401
Date: Sun, 13 Apr 2008 18:11:32 GMT
Server: Apache/2.0.54 (NETWARE) mod_perl/1.99_12 Perl/v5.8.4 PHP/5.0.5

Vary: accept-language,accept-charset
Accept-Ranges: bytes
Connection: close

Using this nice class (adapted to urllib2) as a basehandler I see that no
Authentication-header is being send out:

What am I doing wrong here? I spend almost my entire free time today on this
and couldn't find any problem with my code, anyone else has a thought?
Thanks in advance.
