I utilized the idea from http://www.mssqltips.com/sqlservertip/2778/how-to-add-reporting-services-to-an-existing-sql-server-clustered-instance/ to install 2008 R2 Reporting Services on a new Clustered SQL instance. In short, create the new Clustered SQL instance on Node1, installing Reporting Services with it. Then on Node2, Add a Failover Cluster Node (without choosing Reporting Services); following that up with starting the SQL setup.exe with a cmd to bypass a check so that I can then install the Reporting Services feature on Node2. It points out using the SQL Cluster Network name for connecting to Reporting Services.
I verified upon failover that I could still access the Reports and ReportServer URLs. However, when wanting to add an SSL certificate to the RS configuration, I run into the warning of "mismatched address - the security certificate presented by
this website was issued for a different website's address", where I can continue and get to the Reports or ReportManager URLs.
I played with different certs (internal CA created) and SANs and other things, but I still get this error with the cert. The Reports URL, for example, is <a href="https:///Reports">https://<SQLClusterNetworkName>/Reports, and the
cert has a CN and Friendly Name of SQLClusterNetworkName (with SAN of DNS: SQLClusterNetworkName.<domain>), but the error still happens.
What am I missing to eliminate the mismatched address warning when using the SQLClusterNetworkName as the base of the URLs?
