	// DomainName stores the FQDN of the signing CA (its certificate will have this
	// name embedded). It is usually set to the GUID of the host the Auth service runs on
	DomainName string

	// AuthServiceName is a human-readable name of this CA. If several Auth services are running

  • invites other SSH nodes to a cluster, by issuing invite tokens
  • adds other SSH nodes to a cluster, by checking their token and signing their keys
  • same for users and their sessions
  • checks public keys to see if they're signed by it (can be trusted or not)
