The SAP NetWeaver Application Server (AS) Java delivers Java EE security roles with some of its applications. You manage JEE security roles by assigning them to a user management engine (UME) role. You can then assign users to the UME roles. Developers can assign JEE security roles to UME role by mapping the roles in deployment descriptors. For backward compatibility security roles mapped to the server roles administrators, guests, and all are mapped to the UME roles Administrator, Guest, and Everyone, respectively.
Refer to the security guide of the relevant usage type or application. Any roles you require for a given application should be listed in the documentation for that application.
