I have installed ERP2005, EP and LS business package on a single server.
I have created custom role and user ID for accessing Learning iView.
When I login with custom user ID and click on Learning iView, I am prompted to provide user ID and password second time. After entering user ID and password I can access Learning iView.
I can login to portal using other user ID (e,g, j2ee_admin) that does not have access to Learning iView without any issue.
