Hey There,
I want to use my fingerprint scanner to login through GDM and GNOME Screensaver... I can do this right now partially... It always asks for my password which is maybe secure but annoying at the same time..
I want to use fingerprint login first and if it fails then I want to use password login..
Any ideas for how to do this ?
I'm trying this in GNOME Screensaver but it asks for the password whenever I slide my finger on the scanner..
There are some shortcomings in PAM and the way it is handled in login managers. Here is the setup I had with kde (/etc/pam.d/kde): auth required pam_nologin.so auth sufficient pam_unix.so auth sufficient pam_fprint.so auth required pam_deny.so account required pam_unix.so password required pam_unix.so session required pam_unix.so session required pam_limits.so This is all re-done from memory, as I lost the file (don't forget to put it in NoUpgrade). What happens is the following: If I enter a correct password, then no fingerprint is required. If I enter a wrong password (or none, which I did most of the time), it tries to get my fingerprint. IMO, this is the best compromise, as kdm asks for a password anyway and only scans the finger after I hit enter, so checking the password first makes sense. I guess you can make a similar setup work with gdm. Making kde not ask for a password at all is not possible though.
