Presumably since the latest samba upgrade, the winbind service no longer starts up.

If I run 'systemctl start winbind' it does actually start running, and it works fine for a while but the systemctl command doesn't return; it's waiting for something.

The /run/winbindd.pid file exists and correctly contains the pid of the running winbind dæmon.

After a while, the systemctl command reports failure.

# systemctl --no-ask-password start winbind
Job for winbind.service failed. See "systemctl status winbind.service" and "journalctl -xe" for details.


However, the logs give me no indication about *why* systemd chose to kill the running winbindd:

I have SELinux in Permissive mode, which means this shouldn't be relevant:
