Audit user account email changes

Summary:

We would like to track the changes made to the user account email address

Content (please ensure you mask any confidential information):

The PER_LDAP_USERS table stores the current email address but it doesn't track history/changes that allow an audit trace.

Is there another way to audit on the user account email changes?
