Let me know the exact name of the log file where all the users data exists.

Hi  [mention:0591d80bf3a5406ebeb3855605fe90c0:e9ed411860ed4f2ba0265705b8793d05] ,When you log in to the system, you will see a file named "audit/-" as the first entry. Clicking on that will take you to the next page, where you can search for files named "user_management.csv" and "username_changes.csv." You can download these files to review the types of actions taken on the users.
