Accessing Back-End Systems with a Different User ID 

Use

You want users to log onto back-end systems with a different user ID from the user ID they used to log onto the SAP NetWeaver Application Server (AS) Java. Possible reasons for doing this include:

·        The user has a different user name in the back-end system

●      You want all users of an application to use a specific user when accessing a specific system

User Mapping enables you to map AS Java users to back-end users. User mapping is a form of Single Sign-On. Users do not need to authenticate themselves again when applications connect them to a back-end system.

When applications connect to a back-end system, they rely on a specific infrastructure to provide them with the connection or the connection information. When you configure user mapping for an application, you must know what infrastructure the application requires. The user management engine (UME) supports the following infrastructures for user mapping:

●      User Mapping and the AS Java

To determine which infrastructure your application requires, refer to the documentation for that application.
