Michael,
All Smart Card related questions should be communicated on Apple's SmartCardServices Project Lists over at MacOSForge.org.
A brief debunking of misinformation previously shared on this thread...
There are three methods for associating a Smart Card to a given user account in either the local or remote DS.
PubKey Hash - Default method used by OS X and requires sc_auth
Attribute Matching - requires /etc/cacloginconfig.plist
PKINIT - requires /etc/cacloginconfig.plist and Mac bound to a KDC
All methods require that the smartcard-sniffer line be present in /etc/authorization for catching the Smart Card and gathering the PIN for the associated Challenge Response with the card for use of the Private Key on the card.
Tokend modules no longer ship with OS X (as of OS X Lion), but are freely available for 10.7, 10.8 from Apple's SmartCardServices project at MacOSForge. This is why nothing happens when you insert a reader / card on a vanilla install of OS X Lion or higher. ALL other components of SmartCard Services are present and have even been updated in released versions of OS X since OS X Lion v10.7.0.
Project Site: http://smartcardservices.macosforge.org/
Installers: http://smartcardservices.macosforge.org/trac/wiki/installers
There are also third-party commercially supported solutions from, for example, Centrify, charismathics and Thursby.
".....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...."
No, "smartcard-sniffer" is NOT a name change for PKINITMechanism.
"smartcard-sniffer" performs a swap of the login window (dynamically) and captures PIN
"PKINITMechanism" performs the Apple provided PKINIT services for Login Authentication.
"...Unfortunately Apple dropped support and now it is a requirement in many places, all places that supply Windows-software for this but if you use OS X you have to find your own solution..."
You have the SAME functionality still offered via my installers from Apple's MacOSForge Project
You have multiple commercial solutions as well as noted above: Centrify, charismathics and Thursby.
Please register and redirect ALL Smart Card related questions to one of the appropriate Mailing list on MacOSForge.
