certificate-based authentication

[Dennis.Hoffman at seagate.com]

I have been using XML-RPC to get information from one of our remote
servers.  To improve security, the server now has a certificate installed,
and when I try to access it, I get an 'Unauthorized' exception.  Is there
an xmlrpclib module that supports (client-side) certificate-based
authentication?  If so, where can I get it, and what  is involved in doing
the  authentication? If not, what are my options?

thanks
