I don't plan to use embedded apps, I just tested it and I really can't imagine anyone who can possible like it....I don't plan to use it in production.

As to the re-authentication, I just want to make sure we're talking about the same thing:
I provide my credentials on the nfuse web page and then I see the application list with 3 applications. When I open the forst one it comes up with novell login window, I provide my credentials and I'm in. When I open the second app I see again the novell login window, and so happens with the tird....so you say it's not supposed to be happening?

In my case I don't see any consistency here...some apps (like user manager for domains) don't prompt me for password, application manager does prompt me, groupwise client does, application that runs on w2k but has data on novell sevrer prompts me, notepad doesn't prompt....hell of a mess frankly.
Is the common thread Novell? Try launching anything that requires NT authentication, then try launching anything that requires Novell authentication. I'm not a much of a Novell man, so I don't know much about a Novell/NT enviornment, but my guess would be that it has something to do with Novell. Are you one a AD Doman or a NDS domain? DO you authenticate to a Win2k or NT PDC or to a Novel server? Perhaps the ica passthrough cannot pass log in credentials to a novel server. I'm stumped too, but I do know that Citrix is really NT/Unix app and has little Novell support.
