Is there a way to find which account has removed a user from a User Group in Spectrum?
Any Spectrum version
Spectrum logs an event with this information. To find the event:
In the Contents pane, select Events TAB, search for User Group for instance.
In the example below, the account called "fulano" removed the Test account from the UserGroup.
