I have been testing our SA4000 running 7.0R3 with a test Citrix XenApp 6 server for pass though credentials. But, it keeps prompting me anyways. I did a session trace, and I can see where my username and password comes though... (see below). But Still prompts. I believe XenApp uses version 5.3 of NFuse, and only 5.1 is listed. Could that be the reason? Is there going to be an update?
