Classification: UNCLASSIFIED I'm a Mac user running OS 10.5.8 and using Safari 4.0.4. with 100% success in using a pre-DOD CAC NG issued card (issued in 2007) on a SCR 331 USB reader firmware v5.25 and ActivIdentity USB reader v2.0. I'm able to bind the CAC-Email cert to an https URL using the Keychain Access app. However, Keychain Access is unable to read the certs on my newly issued (2010) DOD CAC. Can you tell me if the CAC-NG (BETA v0.95) Leo <http://static.macosforge.org/smartcardservices/downloads/installers/CAC-NG-v 0.95-beta-leo.zip> (Jan 26, 2010) will resolve this problem? P.S. I tested Keychain Access ability to read a friends DOD CAC issued in late (Nov) 2008 and the certs were viewable and able to add Identity Preference (bind) to a CAC enabled URL with successful access after entering PIN. Also I tried the trail version of ActivClient CAC for Mac which was not able to read the certs from a pre or post DOD CAC NG. For the DOD CAC NG issued card, ActivClient displays message unable to read card message after 5 seconds of trying. For pre-DOD CAC NG issued card, ActivClient shows blue status bar in a loop as if trying to read the card but the app does not reach an end-state after a minute or more running, i.e. neither an error message for display of certs. The DOD CAC NG issued card works with problems on Win XP OS using ActivClient v6.1 via a SCR 331 or SCR 3310. V/r, LCDR Vee Courtney N-NC/J644 (719) 556-0889
