Current situation is as follows:
EP6 SPS14 configured to use SSO with SAPLOGONTICKET to a .Net Application running on MS IIS6.
This works perfectly, as all User IDs are the same.
Now, we have a situation, where the User ID's on the Portal will be different to those used on the .Net Application.
So now I am trying to configure the User Mapping for the .Net Application, but am not having much luck.
The User Mapping has been configured, and is working correctly to our backend SAP Systems.
Any ideas, on how I can get this .Net App to work?
