AFAIR does urlopen() expect the password to be Base64-encoded, not 
urlencoded.

You might also need to add an AUTH-Line. But this all does not matter, 
as there is more than one AUTH-Method you'd have to implement them all, 
but fortunately urllib2.HTTPBasicAuthHandler and 
urllib2.HTTPBasicAuthHandler exist.

So use them:

import urllib2
passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, theurl, username, password)
authhandler = urllib2.HTTPBasicAuthHandler(passman)
opener = urllib2.build_opener(authhandler)
urllib2.install_opener(opener)
pagehandle = urllib2.urlopen(theurl)
