Subject: [PATCH] Fix useradd audit event logging of ID field

When useradd sends its ADD_USER event, it is filling in the id field. This is not yet written to disk. When auditd sees the event and the log format is enriched, auditd tries to lookup the user name but it does not exist. This causes the event to never be resolvable since ausearch relies on the lookup information attached by auditd.

The fix is to not send the id information for any event until after close_files() is called. Just the acct field is all that is

Patch by Steve Grubb (afaik).
