Hi - We have been having some issues with our customer's E2K7 / W2K8 calendaring integration with CUPS 7.0.4. It looks as though E2K7 installs a self signed cert in it's store as part of the install for client email access. This cert CN, however, is based on the DNS name (e.g. E2K7) and not IP and we do not have DNS client enabled on our CUPS server (all UC comms is usig IP addresses). My question is, what is the best way to get CUPS to resolve the E2K7 fqdn (e.g. E2K7.CISCO.COM) ? Can we run the "utils network host" command and specifiy the fqdn, or do we need to use the "set network dns" as the internal nameservers and "set network domain" as the suffix (e.g CISCO.COM). Also - would these commands have any impact on the CUCM connectivity / SIP Domain etc?
thanks in advance
You need DNS for this integration. It is because CUPS can only talks with Exchange via SSL. And SSL requires the request URL match with the CN in the certificate.
As an (unusual) workaround, you may regnerate the Exchange certificate with IP address in subject name.
