redirect via webdispacther; can't get passed logon screen

Hi all,

Im trying to access our SAP ABAP system via our webdispatcher.

The redirect works, as Im getting the logon screen from our SAP abap system that I want to login to.

However, when I fill in my userID and password, nothing happens. The login screen appears again.

Our Webdispatcher doesnt have a DNS name(yet) so I am accessing it via IP :

http://<ip webdispather>:8101

As Im getting the logon screen of our ABAP system, I can assume that the redirect is working fine, and all profile parameters are correct in the webdispatcher.

The only thing I can think of, but cannot test yet, is that the webdispatcher needs to have a DNS name to able to get this working ?
Does anyone have any suggestions ?

Thanks in advance,

Menno
