Set a Service Communications Certificate
Federation servers in Active Directory Federation Services (AD FS) use the service communications certificate to secure Web services traffic for Secure Sockets Layer (SSL) communication with Web clients or with federation server proxies.
The Service Communications Certificate is not the same as an SSL Certificate. To change the AD FS SSL certificate, you will need to use Powershell. Follow the guidance in this article.
You can use the following procedure to change the service communications certificate with the AD FS Management snap-in.
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 (http://go.microsoft.com/fwlink/?LinkId=83477).
