This would set it for the local logs. And you would need to do this on the 
server that is aggregating the logs. (I think I forgot to mention that last 
week.) But for the workstations, you have to set name_format in audispd.conf.

One approach some people take is to use the log_group setting in auditd.conf. 
If there is a group that the security people belong to that others don't, then 
using that group name for log_group this is the easiest way and exactly why 
this option exists.
