Symptom
When you do an "Top N Authentication by Failure Reason" report and click on a number next to a reason expected result is that ISE shows you the list of the authentications matching this reason.
This is displayed correctly for failure reason "24408 User authentication against Active Directory failed since user has entered the wrong password", however for failure reason "24415 User authentication against Active Directory failed since user's account is locked out" it is displayed "No data found".
Workaround
Display these authentications from "RADIUS Authentications" report and filter it with 24415 reason.
Further Problem Description
At the moment the problem is observed with 24415 reason only however other reasons can be affected as well
