So We have noticed a weird issue happening in our (soon to be production) network.
We have 3 IIS Servers, using shared configuration and using Centralized Certificates. Each site has up to 6 bindings (3 for non www for each of the hosts, 3 for www for each of the hosts) Sample IIS Binding Each of the SSL Binding's are configured like this IIS Binding
When we go to the non www version of the site the SSL certificate is picked up fine, however when we go to the www version a mismatch is thrown and it tries to use the hosts wildcard certificate. If I disable centralized certificates, install the cert on the host and set it in the IIS binding for the WWW entries everything works..
Kind of stumped on this one
