running elementary OS 5.1.6 Hera the logout doesn't work anymore after replacing the local account login by LDAP account login.

journalctl reports

Jul 17 15:35:01 eos wingpanel[4311]: EndSessionDialog.vala:184: Unable to logout:
GDBus.Error:org.freedesktop.login1.NoUserForPID: Caller does not belong to any logged in user or lingering user

https://github.com/NixOS/nixpkgs/issues/60496 mentioned a problem with light-locker but I didn't notice a problem with light-locker on the system.

Logout with local accounts work fine.

Any ideas?


For some reason the problem is solved after installing Debug-Symbols:

apt install libnss-ldapd-dbgsym
  • Just noticed that screen locking reports a wingpanel error in journalctl as well: Jul 21 16:56:13 eos wingpanel[1525]: Indicator.vala:163: Unable to lock: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ScreenSaver was not provided by any .service files
