With this feature it is possible to differentiate the login failures in the audit messages, which one is caused by incorrect password and which one is caused by incorrect login.
Before this change, audit messages were only returned for cases when the authentication failed with FAILURE status, which happens when the user provides an incorrect password. The event type is LOGIN_FAILURE in this case.
With the new changes, it is provided audit information for cases when the authentication fails with DNE status by adding a LOGIN_DNE event type. DNE stands for user "does not exist", it always means that the login (email / screenName / userID) is incorrect.
So with the newly added LOGIN_DNE event type we cover authentication DNE scenarios when the login fails due to incorrect login (email / screenName / userID) .
