GMS 2014 R2 running on SLES 11 SP 4. We have run into issues with our self signed GMS server certificate and newer devices. Consequently we want to switch to a third party certificate.

My question is what are the devices expecting to see as the Common Name in the certificate? The reason I ask is, we already have a third party cert in place for GroupWise WebAccess that uses as the common name. Requests hit our firewall and are redirected to a specific server behind the firewall based on a port number and internal ip address.

Could I use this same certificate to secure communincation between our devices and a different server behind the firewall (which directs the requests to a different server based on a different port number and ip)?
