What exactly was typed in at the command line? This is caused by this line of 
code:

https://github.com/linux-audit/audit-userspace/blob/master/lib/
audit_logging.c#L480

The idea is that we want to rely on the number rather than the name. However, 
the log event is supposed to be created after passwd and shadow have been 
updated. So, the audit daemon should be able to resolve the event. 

Maybe useradd needs to be straced to see if it does everything in one shot or 
if it sends multiple events as it builds the user.

I'd say strace useradd will have the answer.

Right. Let's see what the root cause is and then what we can do about it.
