I am unable to use my Government CAC anymore with the Mac. The CAC is recognized in the System.log but is not accessible in Mail.app or any browser. The following is our log… notice that CAC-5FFF-7F00-62FF-00F0-B5D3 is being inserted and added to the keychain. When I remove the card it is removed from the keyhain and when I add it back it is inserted into the keychaing. But when I try and use the CAC with Mail or browsing a CAC required site the CAC doesn't work or initialize in the application. See below, it look like it is trying but getting the deny file-read-data. Help please, I've been trying to get this working since I upgraded to 10.8. I've installed the most recent update (i.e., Smart Card Services Update 2.0b2-ML-signed.pkg).
