auditd syslog builtin plugin



Hi,


I am trying to make the builtin syslog audisp plugin to use a custom
facility/priority pair for the syslog messages exported to the syslog
daemon. For that I am using  the patch and the conf from below.
The problem is that the compile and the start process don't give any
errors when I am using the below customization but the syslog daemon
receive the messages from the audisp with the default facility
(LOG_USER). So I need a littel help here.

I would appreciate any help.

Thanks,
