Note – If you connect to a Windows Server and receive the following message:
The card supplied requires drivers that are not on the system. Please try another card.
then you do not have a supported smart card for Windows and need middleware to
support your smart card in a Windows environment; however, this message
indicates that the smart card channel is operating correctly.
You have now successfully enabled and tested the smart card channel from the Sun
Ray DTU to the Citrix Server.
