To be able to establish connection between the server on which the SDIC is located and the server(s) on which the SLD and the NWDI are located, you must establish a secured Single Sign-On (SSO) connection between the two systems. Once the user is authenticated on the SDIC server, an authentication ticket is generated and is used for further authentication with any of the targeted servers. Therefore you have to establish a trust relationship between the AS Java running the SDIC service and the AS Java running the NWDI
