ADFS 2016 Not Returning XML Unless Localhost

  • 772

I have recently set up an ADFS 2016 server and restored an export from a previous ADFS 2.0 on Windows 2008 R2. Passed the new configuration through MS' analyzer with no issues (except for using a wildcard cert which seems to confuse it).

Using Chrome on the ADFS server, when I surf to the service: (fqdn = adfs.corp.mydomain.com = federation service name)

  1. http://fqdn --> default IIS page
  2. https://fqdn --> cannot be reached
  3. http://localhost/adfs/fs/federationserverservice.asmx --> 503
  4. https://localhost/adfs/fs/federationserverservice.asmx --> XML
  5. http://fqdn/adfs/fs/federationserverservice.asmx --> 503
  6. https://fqdn/adfs/fs/federationserverservice.asmx --> cannot be reached

So, according to the first and fourth responses, I can viably reach the service and it responds with XML. But, I'm not sure why I can't get the response when using the full domain name and path in the last URL? How do I diagnose this?

  1. What about the normal metadata endpoint:

    https://myserver.domain.com/FederationMetadata/2007-06/FederationMetadata.xml

    ADFS only answers to https and in 2016 does not use IIS.
