This question has now been 'moved' to the Exchange 2013 forum.
Can you please help me with certificate choices?
We currently have an Exchange 2013 server publishing OWA, EAS, etc. externally with ISA server and a DigiCert certificate on both servers. The certificate has multiple SANs. Everything is good.
We now want to ditch ISA server and use Microsoft’s Web Application Proxy with ADFS services and I’m looking to simplify the certificate requirements.
I read in the ADFS/WAP certificate requirements that the Subject name (CN) and one SAN entry need to be the same. If I changed the current certificate, I'm not sure whether it would break the Exchange certificate requirements.
So, can you tell me if I can switch to a single wildcard certificate and use it for all these services, i.e. Exchange, WAP and ADFS servers?
Thank you in anticipation,
Andy.
