Installing and Configuring SSF: Front Ends

To use secure store and forward (SSF) functions on front-end applications, install a security product on the front-end system and set the relevant parameters in either the environment variables or the SSF initialization file.

1. Install SAP Single Sign-On or an external security product on each front-end computer where SSF functions are to be used. Note the name and location of the library of the security product.
   Note For installation instructions, see the documentation for your security product.
2. Determine if you want to change the default values of the SSF parameters.

   The following table lists the SSF parameters. Specify their values either in the corresponding environment variable or in the file ssfrfc.ini.
