In a normal system, there will be some events with 4294967295. These should be 
daemons and system events. Anything caused by a user should have the auid set 
to their uid. This is done by pam_loginuid.

cat /proc/self/loginuid

If that shows the account you logged in with, its working. If not, then 
something is wrong with pam or the kernel.
