The Citrix XenDesktop connector requires Sun Ray Software 5.2 or later.
The Citrix XenDesktop connector supports Citrix XenDesktop 4.0 with Citrix Web Interface 5.4.
An issue has been identified preventing full interoperability with Citrix XenDesktop 5.x platforms. Therefore, use of the Citrix XenDesktop connector is now limited to Citrix XenDesktop 4.0.
