Password expiration notification

Hi, folks.
I'm using ADSI / LDAP to authenticate the users of my application and I need to find a way to warn the users when their passwords are about to expire (the same way Windows does when you log in).
Does nayone knows how to get the reamining days before password expiration or how to know if the password expiration date is within the current warning settings (default is 14 days).

Thanks for any input!!
