[gdm-list] Autologin with fingerprint?

["Marco Leise" <Marco Leise gmx de>]

Hello, I just got thinkfinger working and I was wondering if I could get  
gdm to log into my default user account with no typing.
My gdm-autologin looks like this:

#%PAM-1.0
auth       optional		pam_env.so
auth       required		pam_nologin.so
auth       required		pam_permit.so
account    include		system-login
password   include		system-login
session    include		system-auth
session    optional		pam_gnome_keyring.so auto_start

and my system-auth like this:

auth		required	pam_env.so
auth		sufficient	pam_thinkfinger.so
auth		required	pam_unix.so try_first_pass likeauth nullok
account		required	pam_unix.so
password	required	pam_cracklib.so difok=2 minlen=8 dcredit=2 ocredit=2  
retry=3
password	required	pam_unix.so try_first_pass use_authtok nullok sha512  
shadow
session		required	pam_limits.so
session		required	pam_env.so
session		required	pam_unix.so
session		optional	pam_permit.so

All I need is auto-login to wait for an ok from pam_thinkfinger I guess,  
but I don't feel like digging through the documentation for hours to  
realize it can't work or it is a trivial one-liner. Do you have a hint for  
me?

Regards,
Marco
