Citrix XenApp 5 FR2 - Web Interface Pass-Through prompting for U/P

I have created a WI site for our users to access the company apps via a browser and set this site authentication as Pass-Through.
I connect to the site and the I am able to see that the authentication is PT > click OK > see my apps > click on an app > and the Windows RDP login comes up.
Resuming, the WI is not passing through the login details to the server.
Thank you for your help in advance.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I am using CitrixOnlinePluginFull 12.0
When lauching the website I am able to see the published desktops apps right away. The problem is when I launch them, I get prompted to login on the windows GINA... (same one as the RDP login box).
On the workstation, if you go to task manager do you see SSONSVR.EXE loaded?

There is a bug with the 12.0 client that causes this. Citrix posted a work-around.
Citrix will be releasing the new Client soon to address SSOn (Pass-thru) issue with 12.0 client... In the meantime, you could use 11.2 client, which should work without any issue.

Thanks guys, I think this is a mix of Kerberos not being set for the Citrix servers on AD, the client version and XA version.
