SmartCard Software

[admin at kclinux.net]

This doesn't exsist, but I'm hoping maybe it does and someone knows where to
get it.  For Windows 2000 and XP, there are smartcard readers that will log
you in when you insert a smartcard, and log you out when you logout or when
you remove your smartcard.  Is there something like this can be used for KDE
or Gnome on Red Hat 8.0?  The smartcard readers are USB and detects fine.
