The Problem
Error messages from fprintd service lsuch as those below are logged even in the case USEFPRINTD=no has been configured into /etc/sysconfig/authconfig.
Jan 22 13:58:09 hostname dbus[914]: [system] Activating via systemd: service name='net.reactivated.Fprint' unit='fprintd.service' Jan 22 13:58:09 hostname dbus-daemon: dbus[914]: [system] Activating via systemd: service name='net.reactivated.Fprint' unit='fprintd.service' Jan 22 13:58:09 hostname fprintd: ** (fprintd:45376): WARNING **: fprint init failed with error -99 Jan 22 13:58:09 hostname systemd: fprintd.service: main process exited, code=exited, status=157/n/a Jan 22 13:58:09 hostname systemd: Unit fprintd.service entered failed state. Jan 22 13:58:09 hostname systemd: fprintd.service failed.
This happens even after running the command to disable fprintd:
# authconfig --disablefingerprint --update
The Solution
fprintd is a static service, which could be started by someone who sends message “net.reactivated.Fprint” into system Dbus even in the case USEFPRINTD=no in /etc/sysconfig/authconfig.
# cat /usr/share/dbus-1/system-services/net.reactivated.Fprint.service [D-BUS Service] Name=net.reactivated.Fprint Exec=/usr/libexec/fprintd User=root SystemdService=fprintd.service
# systemctl list-unit-files | grep fprintd fprintd.service static
To resolve this issue uninstall “fprintd” package to eliminate the messages, if fingerprint authorization is not necessary.
# yum remove fprintd
or
# rpm -e fprintd
If dependent package “fprintd-pam” has been installed, remove it before removing fprintd.
