3441950 - SPNego Logon does not work as expected after Web Dispatcher Implementation in multiple systems landscape

After a Web Dispatcher is implemented in a landscape where multiple systems are accessed in parallel, SPNego does not work as expected and a logon screen asking for user credentials occurs when such systems are accessed. Refreshing the page may trigger SPNego occasionally.
