Another important thing is: what happens if the user removes the card
after logging in? If the desktop should be blocked then we need some kind
of daemon to provide that. I'm not sure that having so many components
cooperating, the system wouldn't suffer from some kind of race condition.
I think it would be better that the desktop manager were smartcard-aware.

In xscreensaver for instance it would be good that a privileged user could
force log off of current user (ms does that and it's useful). Well, we
have CTRL+ALT+BKSP ;)

GDM doesn't ask me for a password for PKCS#11 module. It asks a username
and then the PKCS#11 asks for the pin (it asks for "Password for token
blah blah blah" and not just "password").

But, as I see it, gdm asks for a username before any pam module is called;
so I assume that to avoid the user name, patching gdm is needed. I wonder,
is this something related to the PAM specification (I mean not having a
specific module to ask for the username but having the program to ask for
it before any pam module is called).

I've been suggested to use gdm autologin feature... Could work as a hack:)


Thanks,

Josep
