A client has recently deployed a Document Management System (called MFiles) in an SBS 2011 environment. The application has the facility for Web Based Access (by creating a New Site under IIS). We have set this up in a test environment (to test access and functionality). When the new site was set up under IIS we assigned it the Port Number 82 (HTTP). We have added Port Number 444 for HTTPS. External access has been set up using an A Record (mfiles.domain.com) and the port number (:82 or: 444) (http://mfiles.domain.com:82 or https://mfiles.domain.com:444).
Because we already use Port 443 for OWA and have a third party SSL for this I was wondering if I can set up another SSL certificate used for accessing the document management web interface on the HTTPS (444 Port) externally. The existing SSL is for a single domain only. Can I just create a new SSL (using mfiles.domain.com)?
The main reason for this is to add additional security for external users accessing the document system.
Any advice would be great.
