We have a domain setup here and use wired and wireless (wifi) lan. Our password expiration period is 30 days. But the people who are at home or are on wifi or are not on LAN (i.e they login with the old password and then connect the lan cable), dont get any password expiration alerts.
I am looking for a software or a script which should send a mail to the user that there password is about to expire. I am looking for the below things.
1) It should send 3 alerts to the user i.e. before 15 days of expiration; then 7 days of expiration and last before 1day.
2) It should be completely automated
