Issue with fprintd 1.94.2-2 and PAM

I allow sudo w/ fingerprint on one of my machines, however since updating fprintd last week I'm always immediately prompted for a password instead. Is anyone else having this problem or maybe have any idea if something changed?

Code: [Select]
# lsusb | grep Fingerprint
Bus 005 Device 006: ID 06cb:00bd Synaptics, Inc. Prometheus MIS Touch Fingerprint Reader
  idProduct          0x00bd Prometheus MIS Touch Fingerprint Reader

Code: [Select]
# cat /etc/pam.d/sudo
#%PAM-1.0
auth	sufficient	pam_fprintd.so
auth	include	system-auth
account	include	system-auth
session	include	system-auth

fprintd-verify also still works as expected, but here's the output from "sudo env G_MESSAGES_DEBUG=all /usr/lib/fprintd -t" anyway

Yes actually. I had to disable pam support for it to build otherwise it kept looking for libsystemd. I'm actually not totally sure how it built in the past (maybe some libsystemd pc hacks). I think master currently supports libelogind so I think next version I should be able to turn it back on.

Actually nevermind, I was able to cherrypick the commit in question so it should work again.
