How to get the authenticated user

Hi all,

I have a pickle of a problem, which I am trying to solve.

The portal we need to implement this on, has Companies implemented, which means something changes in the security model - and makes an authenticated user unreachable for me.

The usual way of getting the user:

com.sap.security.api.IUser sapUser = com.sap.security.api.UMFactory.getAuthenticator().getLoggedInUser();
IUser ep5User = WPUMFactory.getUserFactory().getEP5User(sapUser);

... means that if I subsequently check for ep5User.isAuthenticated(), it always returns false (this is a webdynpro application, so there's no "request" object available to me).

What do I do next? I need the authenticated user, so I can connect to KM, and overwrite files - anonymous write/delete permissions is not allowed on this system.

Points will be awarded for any help 😊
