We are having a problem with configuring the Session Host certificate in our 2012 RDS environment in that the external FQDN (rds.test.com) site name does not match the internal domain name (host1.inside.com).
Using a two server config to start, Gateway/Web roles on the externally facing server and Broker/Session host roles on the internal server separated by another firewall.
If we don't put a Subject Alternate Name on the cert from our internal CA for the Broker/Session host, we get the mismatch errors but we intend to purchase a cert from a 3rd party like thawte.
Anyone else get around this?
