The Websense Citrix Installation Package solved our issue of misidentifying Citrix users, but it breaks the XenApp plugin.
We use the XenApp plugin (formerly known as pnagent or program neighborhood agent). When the package is installed it completely breaks this piece. The XenApp plugin is used to deliver the icons to the users desktops once they log in and is critical to the deployment.
The actual message that comes up is Citrix Receiver could not contact the server. Please check your network connection.
When we remove the package we no longer get errors.
