An other issue is that when 'request->passdb_success' is FALSE, the request fails but the error field is not set (as it is only set when request->failure is TRUE), which make it hard to create metrics for failed login attempts.
We have (assuming success were working as expected):
- success = yes -> means auth OK
- error is present -> means request failed for some reasons
- neither success nor error is present -> means requests failed for other reasons.
As we can't create metric filter testing field absence, getting the count of failed requests would mean create 2 metrics (one for success, one for all) and diff the 2 to get the count of failed attempts.

Hi,
I'm playing with the new events, and encounter some issues:
First the 'auth_request_finished' event is documented as having a 'successful' field, but in the code, the field is defined as 'success' (e->add_str("success", "yes")).
But more important, in the function "auth_request_success_continue()" (auth/auth-request.c:288), "auth_request_log_finished(request)" is call (line 303) before updating the request status: "request->successful = TRUE" (line 312)
So the log function never set the success field to "yes" as at this point request->successful is still false.
