This configuration parameter specifies the path to the PKCS #11 module to be used by smart card components on the computer.

By default, smart card components use the Centrify Coolkey PKCS #11 module. However, Coolkey does not support all smart cards so you may specify a different module if necessary by specifying the absolute path to your PKCS #11 module with this parameter. For example:

rhel.smartcard.pkcs11.module /usr/$LIB/pkcs11/opensc-pkcs11.so

Note:   In the path specification, this parameter supports the use of the $LIB environment variable, which allows a single path specification to work for 32-bit and 64-bit systems. At run time, on 32-bit systems, $LIB resolves to lib, while on 64-bit systems it resolves to lib64.

After changing the value of this parameter, you must re-enable smart card support by running the following sctool commands as root:

[root]$ sctool --disable
[root]$ sctool --enable

Also, refresh the GNOME desktop by running the following command as root:

[root]$ /usr/sbin/gdm-safe-restart

In most cases, you set this configuration parameter using group policy.
