When logging on through an HTTP or FTP client, standard user/password authentication is used. The user is mapped to an Integration Server session, and a service calling an SAP system is executed. This service uses the logon parameters associated with an RFC connection that likely does not reflect the identity of the original HTTP client. The user configured for the RFC Connection is usually a pool user shared among several physical users. This pooling allows for optimal performance.

If your RFC connection is configured to use SNC, a secure connection to the SAP system will be established. You need to install and configure the correct *sapcrypto.* library for your platform. This library supports SAP's Secure Network Communication (SNC) Standard. SNC works on top of the RFC protocol.
