• Please can you give root CA and intermidiatory certificate for CN=Red Hat Entitlement Operations Authority. So that we can put those into our cisco WSA proxy.
  We think that we need those certs inorder to work.

CN=Red Hat Entitlement Operations Authority,OU=Red Hat Network,O="Red Hat, Inc.",ST=North Carolina,C=US

• Testing result with cdn.redhat.com:

#  openssl s_client -connect cdn.redhat.com:443 -CAfile /usr/share/rhn/RHNS-CA-CERT
CONNECTED(00000003)
depth=1 C = US, O = "Cisco IronPort Systems, Inc.", ST = California, L = San Bruno, CN = Untrusted Certificate Warning
verify error:num=19:self signed certificate in certificate chain

• Satellite.rhn.redhat.com works fine as we think that we have Root CA for CN=RHN Certificate Authority.
