capture mount event in /var/log/audit/audit.log

Hi Everyone, in RHEL 5.5 kernel 2.6.18-194.el5 audit-1.7.17-3.el5 Have the following in the /etc/audit/audit.rules ## non-privilege users using mount command. -a exit,always -F arch=b32 -S mount -F auid>=500 -F auid!=4294967295 -k export -a exit,always -F arch=b64 -S mount -F auid>=500 -F auid!=4294967295 -k export from a general user account $ mount /dev/hdc /dev/cdrom mount: only root can do that but /var/log/audit/audit.log does not capture this event Any input is much appreciated! Thanks in advance Betty
