Setup SAML SSO on Coldfusion 2016 Server -- 2

Need to setup SAML single sign on for a website where members will first login with their username and password and then be able to click a link, get authenticated using SAML and then be redirected to that service provider. This will be on a Windows 2016 Server with Cold Fusion 2016 Standard Edition. We were already given a Identifier (Entity ID), which points to a metadata.xml file, a Reply URL(Assertion Consumer Service URL) and the Sign on URL from the service provider.
We now have to create a PEM file, send it to them and setup the SAML single sign on.
