Subject: [PATCH] pam_systemd: suppress LOG_DEBUG log messages if debugging is
|
|
|
6f381c |
off
|
|
|

|
|

In the PAM module we need to suppress LOG_DEBUG messages manually, if
|
|
|
6f381c |
debug logging is not on, as PAM won't do this for us. We did this
|
|
|
6f381c |
correctly for most log messages already, but two were missing. Let's fix
|
|
|
6f381c |
those too.
