I have a Sharepoint 2013 Farm, with a webapp on it that I have configured to authorize users using A trusted idp, in this case I use AD FS WS-Fed so that I can use claims. I want to change from using http (port 80) to https (port 443).
If I go to sts.contoso.com/adfs/ls/idpinitiatedsignon I can sign on as a user from my AD, so ADFS is set up correctly. However, I think my problem is that I cannot get https to work, and the relying party needs an https connection when accessing the _trust endpoint during sign in. I am basing this on the fact that I am getting a 403 you must be signed in when I try to access my webapp using my http url.
I have followed this guide for setting up https, and several others. But for some reason I get a "Website not found" every time I try to access it using https, even when all the mapping have been done and IIS configured. It is a simple config and I get no real errors, so can't figure out what is wrong, is there a step missing from this guide, or some common mistake people make?
Are mapping not enough? Do I need to extend to another zone?
