EP6: SSO with User Mapping

Hi,

I'm trying to define a System for integrating an external http(s) application like the

one mentioned in the PPT slides from TechED / Basel.

On one slide a system is created based on portal archive "com.sap.teched2003.system.webapp"

which is configured to point to URL "http://localhost:50000".

I'm using "SAP J2EE Engine Version 6.20 PatchLevel 67440.20" - but in this version

I can see just system templates for EP5, JDBC, SAP, Unification and Yahoo.

Does anyone know how to define such a system? where to get more information?

Any hints are welcome!

Thanks in advance,

Rüdiger
