APM ADAuth Password Change Logging

Within our APM policy we are using ADAuth module and the Change Password label on the logon page. So when a user's password has expired or the check box on the logon page has been enabled, the ADAuth module prompts for a new password. Whilst this all works - I need to log the fact that the user changed their password.

 

Is there any setting I can enable to log APM ADAuth changing the user password?

 

Does APM ADAuth module set some session variables that can be queried to check if password was changed and hence can be used in VSE to do the logging?
