Re: [Fed-Talk] CAC-enabled login OS X10.7 & 10.8

I'm well aware of the sc_auth command and on previous versions of OS X I had CAC login enabled.  However, in testing an OS X Lion and an OS X Mt. Lion system, inserting the CAC card has no effect.  Both systems otherwise have full CAC functionality and I used the Identity Private Key.

I have not yet tried this on a clean system with no security configuration (disabling suid's binaries, etc.) so it is possible that both systems have been broken with regards to CAC login.

I was hoping someone could actually confirm what setup works on OS X 10.7 & 10.8 because at present the discussed information has not worked for me.

Looking at /etc/authorization under system.login I see:

                                builtin:policy-banner
                                loginwindow:login
                                builtin:reset-password,privileged
                                builtin:forward-login,privileged
                                builtin:auto-login,privileged
                                builtin:authenticate,privileged
                                PKINITMechanism:auth,privileged
                                loginwindow:success
                                HomeDirMechanism:login,privileged
                                HomeDirMechanism:status
                                MCXMechanism:login
                                loginwindow:done

and under authenticate I see:

                                builtin:authenticate
                                builtin:reset-password,privileged
                                builtin:authenticate,privileged
                                PKINITMechanism:auth,privileged

Comparing against 10.4 references these seem to indicate that smart card login is already enabled, besides the name change from smartcard-sniffer to PKINITMechanism.
