Setting Up Your Smart Card
Follow the instructions in this chapter to learn how to enable
smart card services and configure your computer to use
smart cards.
Smart card services are preinstalled with Mac OS X v10.4 Tiger or later, but smart card
login and system administration are not enabled. You can enable smart card login on
any system with or without a smart card reader attached.
When the smart card services are enabled, your computer checks whether a smart card
reader is attached. Enabling smart card login does not affect performance even if a
card reader is not attached. If a card reader is not attached, you can continue to use
your user name and password to log in.
Enabling Smart Card Login
To enable smart card login, you must edit the /etc/authorization file. To modify this file,
you need an administrator password and you must be authorized to use the
sudo
command in Terminal to modify the system’s configuration files. You must also be
familiar with editing text files using a terminal text editor such as pico; a text editing
application; or a property editor such as Property List Editor, which is included in the
Apple Developer Kit.
Follow these steps to enable smart card login:
1 Open the Terminal application, located in the Utilities folder in the Applications folder.
2 To access the authorization files, enter the following command in Terminal:
sudo -s
3 To navigate to the correct directory, enter:
cd /etc
4 To delete the outdated authorization.cac file installed on your computer, enter:
rm authorization.cac
