I have a implemented a provider hosted App inside the SharePoint 2013 server (the certificates .cer & .pfx taken from the IIS of same server) and able to get the result. However I am not clear about taking the certificates in the multi server environment (SharePoint Server & IIS server for remote web app).
can anyone please suggest from which server (Sharepoint Server or IIS server) do I need to take the .cer & .pfx files to configure multi server environment ?
Thanks
