We need to know who they logged in as. Some people login and then do 'su root' 
and perform actions. We need to know who root logged in as.

I suppose they are considered the same person.

Its a way of getting kernel information to userspace.

Actually, the audit subsystem decides where to send things - to special daemon 
or syslog. The information is being passed to userspace for a reason. Some 
installations require it has to be logged with great care. Syslog does not 
meet the requirements for those users.

That's what the userspace daemon does.
