I'm bet that most people asking to audit "failed logins" are actually 
asking to log "failed password attempts" (and maybe "failed Duo 
validations"); i.e. they want to "audit" the authentication process 
rather than (or more likely in additional to) the normal audit 
processing showing what was sent to the SP. At least that's our case.

To get this, I hacked up the ValidateUsernameAndPasswordLDAP class to 
insert log messages matching our old SSO system, but I wouldn't 
recommend that as a general approach.  The ldaptive log messages 
actually come pretty close on INFO, though I think all the 
username/password failures end up with a generic 
"AUTHENTICATION_SYSTEM_FAILURE" rather than the ideal of the LDAP result 
codes like "Invalid credentials".
