SYMPTOM
Upon execution of the out of the box Enterprise Manager report, "82. Unused/Inactive Users" report, users see that the results show "NEVER USED" in place of actual username. This issue is seen only for a case where the Enterprise Manager Warehouse resides on a MySQL database.
See screenshot below.

CAUSE
The issue is caused due to the default VLDB settings selected for MySQL.
ACTION
Follow the steps below to change the necessary VLDB properties.




Making these three changes to the VLDB Setting will produce the desired results for the "82. Unused/Inactive Users" report.
