This file can contain a single root certificate-authority (CA) certificate, or any combination of root CA and associated intermediate CA certificates. The certificates are used to both validate the server and define a valid chain for the client certificate provided in server.tls.certificateFile.
If server.inet.tls.verify is set, this parameter must also be set.
