/var/log/auth.log missing

[Janos Dohanics]

Hello List,

Just discovered that on one of my boxes (FreeBSD 9.3-STABLE #0
r286291) /var/log/auth.log is missing.

/etc/syslog.conf:

# $FreeBSD: stable/9/etc/syslog.conf 238473 2012-07-15 10:55:43Z
# brueffer $
#
#	[commented stuff]
#	Consult the syslog.conf(5) manpage.

/etc/periodic.conf:

monthly_statistics_enable="YES"
monthly_statistics_report_devices="YES"
monthly_statistics_report_ports="YES"
daily_clean_hoststat_enable="NO"
daily_status_mail_rejects_enable="NO"
daily_status_include_submit_mailq="NO"
daily_submit_queuerun="NO"
# 406.status-gmirror
daily_status_gmirror_enable="YES"

I have restarted syslogd, however, no /var/log/auth.log, even though I
took actions such as ssh login which should trigger entries
in /var/log/auth.log.

How can I fix this problem?

Any guess what might have caused /var/log/auth.log not be created?
