• Server Single Sign-On - Microsoft Single Sign-On (password is sent in clear text from SharePoint to
server running Presentation Server)
• After I configure the Citrix SSO, I am prompted to configure the Administration of Single Sign-On
Integration. After I complete the required information, I select apply successfully.
Here is some additional information to note. We have configured a Citrix page off of out IT Staff site. On
the Citrix page, the only thing that is included is the Citrix Web part. When a user logs in one time, the
Citrix application menu, client error, and stored credential error appears. A few minutes later, the no
resources found appears.
Here are the two errors that appear in the event logs:

the server that could be stripping cookies?
When we click on the wizard, we get the error “web page can not be found”. From the quick launch
menu, the Client Wizard is define as
We copied the client files to the following location on the server – “C:\Program Files\Common
Files\Microsoft Shared\web server extensions\12\CitrixAccessPlatform\3663fc13-d7f1-4821-b915-
