Bug description:
[ Impact ]
No fingerprint errors are exposed on fingerprint login failures.
from journalctl, gdm-fingerprint shows error there after retried 5
times of fingerprint login failed, so I open this issue here.
[ Test case ]
1. enroll fingerprint for your right index finger.
2. logout
3. login and try login by incorrect finger e.g. middle finger
4. Each time the wrong finger is used an error is shown
5. After 3 times retries, an authentication error is shown, suggesting
to use another method.
[ Regression potential]
Wrong errors are shown during both fingerprint auth and other kinds of
authentications.
Password failures aren't properly exposed. Verification can't restart on
error.
Password authentication doesn't work anymore for users with no
enrolled prints (as per LP: #1915570)
