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.
IOW, the "id" field is numeric and the translated data at
the end of the
raw record has "ID=unknown(number)".
I'm guessing it is because until the user data has been successfully
entered, there is no translation. Perhaps the event submission should
wait until that happens?
I'd say strace useradd will have the answer.
I may be able to dig out the name from other related generated
events,
but that is kind of a pain.
Right. Let's see what the root cause is and then what we can do about it.
