Description of problem:
When i run:
up2date -u
i see the following output:
There was an SSL error: [('SSL 
routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')]

If i execute: 
openssl s_client -connect xmlrpc.rhn.redhat.com:443 -CAfile /usr/share/rhn/RHNS-
CA-CERT

The last line give:
Verify return code: 10 (Certificate has expired)

My system date is good but in /usr/share/rhn/RHNS-CA-CERT i see the expire date 
as follow:
Validity
Not Before: Aug 23 22:45:55 2000 GMT
Not After : Aug 28 22:45:55 2003 GMT

I think that all systems has this certificate date.

What's going on?
