am trying to implement SSO from Non SAP system (CAS - Central authentication system) to SAP Portal. I have configured the HTTP Header Login module in the Login Module stack as per the below link.
I have developed a Test JSP which set's the Header Variable IV_HTTP_USER with Portal login ID and re-directs to SAP Portal. When we test now, the HTTP Header Login module doesnt succeed and Login page comes up.
I have generated trace from NWA-Troubleshooting->Security troubleshooting wizard for authentication type and below the error i see. IV_HTTP_USER variable always show's as null.
Few Questions I have:
1. Do we have to change Authschemes file inculde authschem "Header" as mentioned in the below thread.
2. In case yes - I did change the authscheme's file as per above discussion and checked. But when i navigate to NWA->Configuration Management Security Authentication and Single Sign-On, I get and information saying Authscheme file is invalid.
Portal Version: NW7.3 SP08
