https connections fails under intel MAC OS X 10.6.6 and 10.6.7 using httplib and/or urllib2 connecting to an IIS web server  requesting basic authentication and a client certificate.

This is an issue with MAC OS X 10.6.x, because I tried these very same  scripts under RHES 5 x64 with python 2.6.5 and python 2.7.1 and they both run just fine.


----------------------------

Sample code with urllib2:

import urllib2
response = urllib2.urlopen('https://www.finratrace.org/')

------------------
Sample code with httplib

import httplib,base64

key,cert=('/tmp/cert_nopwd.pem',)*2
HOSTNAME = 'www.finratrace.org'

username,password='myuser','mypass'

base64string = base64.encodestring('%s:%s' % (username, password))[:-1]


conn = httplib.HTTPSConnection(HOSTNAME,key_file = key,cert_file = cert)
conn.putrequest('GET', '/')
conn.putheader("Authorization", "Basic %s" % base64string)

conn.endheaders()
response = conn.getresponse()

-----------------------

Both samples send the following error:

I also compiled py 2.7 getting the same error message.

I tried patches from Issue7291, but did not work.
