Description Joachim Frieben 2017-09-14 18:08:33 UTC 
Description of problem:
SELinux is preventing (fprintd) from 'mounton' accesses on the directory /var/lib/fprint.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that (fprintd) should be allowed mounton access on the fprint directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c '(fprintd)' --raw | audit2allow -M my-fprintd
# semodule -X 300 -i my-fprintd.pp

Comment 2 Kamil Páral 2017-09-15 14:14:26 UTC 
Seems to violate:
"There must be no SELinux denial notifications or crash notifications on boot of or during installation from a release-blocking live image, or at first login after a default install of a release-blocking desktop. "
https://fedoraproject.org/wiki/Fedora_27_Final_Release_Criteria#SELinux_and_crash_notifications

This is a default system (VM).
Comment 3 Dominic P Geevarghese 2017-09-17 14:30:56 UTC 
whenever authentication related tasks; login as normal user then su - , try to unlock an existing login session, taking a lot of time to respond and fprintd alerts are logged at backend

Comment 6 Kamil Páral 2017-09-19 09:20:24 UTC 
The login prompt delay (gdm, sudo, su) seems to be gone with the update. Proposing as BetaFreezeException, the login delays are very very annoying.
