Import a Server Authentication Certificate to the Default Web Site
Applies To: Windows Server 2012
After you obtain a server authentication certificate from a certification authority (CA), you must manually install that certificate on the Default Web Site for each federation server or federation server proxy in a server farm.
For Web servers, you must manually install the server authentication certificate on the appropriate Web site or virtual directory where your federated application resides.
If you are setting up a farm, be sure to perform this procedure identically—using the exact same settings—on each of the servers in your farm.
Note
The AD FS Management snap-in refers to server authentication certificates for federation servers as service communication certificates.
Membership in Administrators, or equivalent, on the local computer is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).
