A smart card is a small plastic card that is embedded with a computer chip. Many government agencies and large enterprises use smart cards to authenticate users who access their computer networks. One type of smart card used by the United States Department of Defense is called a Common Access Card (CAC).

Administrators can enable individual Horizon Connection Server instances for smart card authentication. Enabling a Connection Server instance to use smart card authentication typically involves adding your root certificate to a truststore file and then modifying Connection Server settings.

All client connections, including client connections that use smart card authentication, are SSL enabled.

To use smart cards, client machines must have smart card middleware and a smart card reader. To install certificates on smart cards, you must set up a computer to act as an enrollment station. For information about whether a particular type of Horizon Client supports smart cards, see the Horizon Client documentation at https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
