I'd like to get some ideas on how to better manage users request for a password change. We have a AD infrastructure with your typical network security in placed. I'd like to know how to manage a password change request via a helpdesk call request. Users call into our helpdesk and will just give there name and request a password change. I want to better that process to ensure the proper security measures are in placed to handle these request. What are some ideas one could use?
