Thank you, Kai !
We'll surely check up on these points.
We did try using HTTPwatch, but nothing substantial came up in the trace :(
Is there something different about the way IE 11 handles security...i.e. it passes the creds. in the URL string.
Safari, Chrome & Firefox work perfectly Ok.
We have a setting in SAP that says: Deactivate login XSRF protection...after setting this, the Login page keeps popping up again n again...i.e. it refuses to move further.
The only difference is that now we don't see the "Logon with URL parameter not possible; logon cookie is missing" error...but the issue stays :(
Thanks a lot !
