  • You will also find that if you try to execute FsConfigWizard.exe, you will get stuck on the "Specify the Federation Service Name" step without the ability to click Next or specify another SSL certificate.

 

Cause

  • The Federation Service parses the Federation Service name (hostname) from the SSL certificate configured for the default website. The service fails to start if the certificate you have bound to the website contains a subject and/or SAN which is not a valid Federation Service name.

Resolution

  • Bind an SSL certificate to the default website which has a valid Federation Service name and then run the initial configuration again.

More Information

  • The FsConfig.exe utility has a /federationservicename parameter which you would think might get around this problem, but it will still fail if you try to use the parameter while using an SSL certificate with an invalid subject and/or SAN. It performs a check to see that the federationservicename you specified matches the subject name of the SSL certificate. It fails with the following error:

"The following error occurred: The Federation Service name specified with the paramter federationservicename and the Subject name in the SSL certificate do not match."
