OpenPGP card and poldi-ctrl

Hi Markus,

What you are seeing with gnome-keyring is normal. The database of
gnome-keyring is encrypted with a password that is usually the same as the
login password. Therefore when you login with password, your gnome-keyring
database gets automatically decrypted and you can access your WPA protected
Wifi (if using network-manager) network without entering any additional
password. Now when you login with an OpenPGP card, you can no longer decrypt
the gnome-keyring database. I haven't found a practical way to avoid that.
One alternative could be to use an encrypted space (truecrypt/encfs...) to
store the gnome-keyring database and other home related information and
therefore get rid of the gnome-keyring password. But you will still have to
enter a password to unlock this encrypted space ;(
