Cause
These issues are specific to the Citrix virtual channel passthrough feature of SecureLogin. With the recent version of Citrix XenApp/XenDesktop, the initial credential passthrough is taken care by Citrix itself. In other words, Citrix and Microsoft terminal server provide the same functionality as that provided by SecureLogin, resulting in conflicts.
