Notify Windows Users of OD Password Expiration
I'm running an Xserve with Snow Leopard Server installed running Open Directory. Our client machines are Windows 7, which cannot integrate with the old domain standard used by Open Directory, so we use pGina as a credential provider. Users' passwords are set to expire every six months.
My problem comes when a user's password expires: there is no notification given before the password expires. When users go to the built-in "change password" website on the server, they are unable to change their passwords because they cannot log in with the expired password, and are basically locked out of the server.
How can I provide some kind of notification to users before their password expires? An email or something through pGina would be sufficient.
