I'm running a Policy Server and I'd like to know where the FederationCertificate Store is located.
At first glance, from Policy Server 12.x, the certificates are locatedwithin the Policy Store in a specific section called CDS (CertificateData Store). You can access them with the AdminUI and also get somedetails running XPSExplorer command.
Synchronize Key Database Instances for r6.x
"Previous versions of the Policy Server used a local smkeydatabase tostore certificate data. Each Policy Server required its ownsmkeydatabase. For versions 12.5x and later, a centralizedcertificate data store (CDS) replaced the smkeydatabase."
