We are attempting to use the DoD Siprnet Token on Mac OS X 10.7.5 and 10.8 but are running into some issues. The token is a Safenet SC650 with a coolkey applet loaded on it and we are using Omnikey 3121 and SCM SCR3310 card readers. Since there is a coolkey applet on the card we believe we need to install coolkey to be able to read the applet. Trying to compile coolkey from source on the OS X was not working for us so we got a copy of the Red Hat ESC software for Mac, which includes coolkey, and installed it. We also have installed the latest Smart Card Services package. Now when we insert the Siprnet Token into the reader the OS X system shows some information about the token but then it reports coolkey crashed. If we attempt to look at the token in Keychain Access we see a token labeled "JPKI-card #<N>", where <N> is a number that sequentially increases every time we insert the token. So we were wondering if anyone had any thoughts on what might be going on or any ideas on how to get this working? Kebba Sallah PKE Engineering Support
