Description of problem:
winbindd is shipped with the following .service file:
Type=notify
PIDFile=/run/winbindd.pid
ExecStart=/usr/sbin/winbindd "$WINBINDOPTIONS"
Default WINBINDOPTIONS are empty string.
Internally winbindd does double fork and notifies systemd about main process
PID change at lib/util/become_daemon.c:become_daemon()
Apparently this confuses systemd as Type=notify daemons aren't supposed to double fork.
We got report from user which reboots system often and every once in a while winbindd doesn't actually start despite reporting OK status. Manual restart fixes the problem.
We got confirmation that using
WINBINDOPTIONS="-F --no-process-group"
(and deleting PIDFile line for a good measure) makes winbindd startup reliable.
Version-Release number of selected component (if applicable):
samba-4.6.2-11.el7_4.src.rpm
et al
How reproducible:
rarely
Steps to Reproduce:
1. reboot machine until winbindd doesn't start
Actual results:
Expected results:
winbindd starts 100% reliably
