This release of SAP NetWeaver Application Server (AS) Java replaces the previous SPNego configuration application with a version based on a proprietary API instead of the GSS API delivered with the Java Development Kit (JDK). For backward compatibility, the AS Java delivery includes the legacy application for SPNego configuration.
We recommend using the new configuration application. It has the following advantages:
Different resolution modes per realm
Support of additional encryption types
Ease of use
