The DualShield SSO Server is a server application on its own. However, the DualShield installation program always installs a copy of the SSO server as a service in the platform in the same place where DualShield authentication server and management console are installed. The DualShield management console uses the SSO server as its login server. You can use this copy of SSO server or install a separate, standalone SSO server depending on your requirements and infrastructure.
