CAC (Common Access Card) help for your personal computer

LINUX SUPPORT PAGE

I received an email letting me know that a Soldier got the CAC working on:

Linux Debian "Etch" using GemPlus USB Information

Ubuntu 8.04 (Hardy Heron) with Mozilla's Thunderbird for email, and got the CAC reader to work with Thunderbird.  He used Coolkey to get the CAC reader working in Firefox, then loaded Coolkeys pkcs module into Thunderbird, and that did the trick.

Ubuntu forums for CAC support

Another Ubuntu forums website where you can read about configuration / utilization of your CAC.
