urllib2 and HTTPBasicAuthHandler

Hi all,
I started to use urllib2 library and HTTPBasicAuthHandler class in order to authenticate with a http server (Zope in this case).
I don't know why but it doesn't work, while authenticating with direct headers manipulation works fine!
WinXP Sp2
Python 2.4.4
Thanks in advance for your help/comments
# TestAuthHandler.py
import base64, httplib, urllib2
httplib.HTTPConnection.debuglevel = 1
#
def TestAuth(method):
data = {'prot':'http','user':'admin','pass':'xxxxxx','host':'localhost','port':'8080','path':'manage','realm':'Zope'}
url = '%(prot)s://%(host)s:%(port)s/%(path)s' % data
req = urllib2.Request(url)
#
if (method == 'headers'):
base64string = base64.encodestring('%s:%s' % (data['user'], data['pass']))[:-1]
req.add_header("Authorization", "Basic %s" % base64string)
elif (method == 'handler'):
auth_url = '%(host)s:%(port)s/%(path)s' % data
auth_handler = urllib2.HTTPBasicAuthHandler()
auth_handler.add_password(data['realm'], auth_url, data['user'], data['pass'])
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)
#
f = urllib2.urlopen(req)
data = f.read()
print data
#
TestAuth('headers')
TestAuth('handler')
