From 87cf5e4b24432d6ee5aa3f5604fbe6ace9cf6e2d Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Mon, 19 Nov 2018 11:39:45 +0100 Subject: [PATCH] pam_systemd: suppress LOG_DEBUG log messages if debugging is off In the PAM module we need to suppress LOG_DEBUG messages manually, if debug logging is not on, as PAM won't do this for us. We did this correctly for most log messages already, but two were missing. Let's fix those too.
