AD password reset in PHP

I need a small webapplication in the layout of [[login to view URL]][1] where a user can: 1.? ? ? ? ? ? Login, if user is validated on the Active Directory, the user can change the password (entering password twice) 2.? ? ? ? ? ? Retrieve password by telling, forgot password, entering email address or username. In behind an LDAP lookup takes place to see if the email address or username exists in the Active Directory. If this is the case, reset the password and sent a mail to the user (from username do an email lookup on the AD) Merijn ## Deliverables site will run CentOS and Apache. If PHP modules are needed to be installed please let me know
