fprintd on lock screen

Im wondering what file I need to configure inside of

 /etc/pam.d/{login,su,sudo,gdm,lightdm}

fprint Wiki

to be able to use fprintd on the lightdm/xfce4 lock screen.
I've managed to get it working on the switch user screen, however, it seems to not transfer over when using the lock screen.

What about

/etc/pam.d/xfce4-screensaver 

?

Re: fprintd on lock screen

Trying to work through this too and have tried adding to that file with no success...

$ rg fprintd *                         
system-local-login
3:auth      sufficient pam-fprintd.so

system-auth
3:auth       sufficient                  pam-fprintd.so

lightdm
2:auth        sufficient  pam_fprintd.so

xfce4-screensaver
1:auth  sufficient pam-fprintd.so

I'm prompted during login (via lightdm) for fingerprint but not by xfce4-screensaver when trying to unlock.

Re: fprintd on lock screen

I found my problem, I had mistakenly written pam-fprintd.so in three of the files when it should have been pam_fprintd.so.

I now get prompted for finger print by xfce4-screensaver.
