Please explain the flow involved. I assume a user logs onto ABAP system first using web browser. During this logon the ABAP system is issuing an assertion ticket which you can see in fiddler. Is this correct ? What happens next ? Is user redirected to Java stack in same browser session ?
The HTTP 401 is normal when using SPNEGO on Java (or on ABAP if a product that supports this is installed). The browser is supposed to respond to the HTTP 401 with a HTTP message containing an Authorization header.
Thanks
