Hi Valters,

This really seems to be a systemd issue: sssd never sets SYSLOG_PID when calling sd_journal_send(), yet journalctl shows e.g. SYSLOG_PID=sudo instead of an empty string. Looks like systemd is mixing the variables or leaking one into the others. The sssd upstream patch you pointed to may act as a partial workaround, but the logging is still odd as you noted.

The sssd upstream devs agree the problem is likely on the systemd side in the bug report you opened [1].

I tried to install systemd and its dependencies from Groovy and Hirsute on a Focal system as a rough way to see if a newer version of systemd fixes the issue, but it kept behaving exactly the same.

I think debugging this requires writing a reproducer in the form of a minimal C program calling sd_journal_send() like sssd does, having it log/set SYSLOG_PID even when it should not.

I'm adding a systemd task to this bug report.
