Since there can be many different certificates on a CAC card, you will
need to tell Cirrus LT which certificate to use to connect to the VPN.
If you are unsure which certificate to use, you can ask your system ad-
ministrator. To view a list of certificates to choose from, click on Cert,
as shown below.
Once you click on Cert, it will take you to another screen (shown
below) that lists the available certificates for you on the CAC card.
Select the Certificate as per instructions from your system administra-
tor. If you don't see the correct Certificate on the list, click the Refresh
button.
