Problem connecting to https using ZSI (openssl problem) - python2.3

[Adil Hasan]

 Hello,
       I'm having problems trying to use ZSI to connect to a https url.
 I give the command and I get prompted for my X509 cert pass-phrase, but
 the program dies with an openssl error.

 Here's my code:

 from ZSI import *
 u=''
 n='https://shahzad.fnal.gov/edg-voms-admin/uscms/services/VOMSAdmin'
 b = Binding(url=u,ns=n, ssl=1, \
             host='shahzad.fnal.gov',port=8080, \
             cert_file='/home/hasan/.globus/usercert.pem', \
             key_file='/home/hasan/.globus/userkey.pem')
 b.listCAs()

The traceback I get is:
Enter PEM pass phrase:
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/local/python2.3/lib/python2.3/site-packages/ZSI/client.py",

  File "/usr/local/python2.3/lib/python2.3/site-packages/ZSI/client.py",

    self.h.connect()
  File "/usr/local/python2.3/lib/python2.3/httplib.py", line 961, in
connect
    ssl = socket.ssl(sock, self.key_file, self.cert_file)
  File "/usr/local/python2.3/lib/python2.3/socket.py", line 73, in ssl
    return _realssl(sock, keyfile, certfile)
socket.sslerror: (1, 'error:140770FC:SSL
routines:SSL23_GET_SERVER_HELLO:unknown protocol')

Any ideas about this? Does anyone know how to solve this problem? I have
seen one post here with a similar problem, but haven't seen any
resolution.

Help!

thanks, adil
