I have added godaddy certificates to the CUP, CUCM and Unity Servers. All are installed correctly because TAC installed them for me. The https web pages respond properly on all servers and even the Jabber for MAC clients no longer prompt for certificates however the Jabber for PC clients still do not recognize the certficates. I have verified that the certificates are being presented to the clients and are valid in addition I have verified the host name matches and the root and intermediate certificates are installed on the servers.
Jabber for MAC version: 9.2.1 147214
Jabber for PC version: 9.2.6 12639
CUP Server Version 8.6.2 10000
All the latest versions.
