Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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
