User Authentication and modification logs shows blank data in Audit report

Hi,

I enabled auditing for Oracle Platform Security Services under Manage Audit Policies. I am reviewing the audit data using Tools → Audit Reports and selected Product = Oracle Platform Security Services. The available Event Types include Authentication, Credentials Creation/Modification, Role Membership, etc.

To test this, I performed the following actions:

• Reset a user’s password
• Created a new user
• Added roles to a user
• Attempted both successful and failed user sign-ins (including wrong password)

However, the audit report only captures role membership changes. It does not capture:

• User sign-in or sign-out activity
• Authentication failures
• Password resets or credential changes

Kindly Clarify:
