SNC Authentication

This page shows how to use encrypted communication via Secure Network Communication (SNC) between yunIO and SAP.

Prerequisites

  • SNC must be configured in your SAP system. For more information about SNC configuration in SAP, see SAP Help: Configuring the Application Server.
  • Check the SAP profile parameter snc/gssapi_lib in SAP (transaction RZ10) to determine, which library is used for encryption in your SAP system. Your SAP Basis has to import and configure the same library on the application server and on the machine that runs yunIO, e.g., sapcrypto.dll.

For information on how to set up SNC via X.509 certificate, refer to the Knowledge Base Article: Enable Secure Network Communication (SNC) via X.509 certificate.
