Drupal and Active Directory

Hi Guys,

Im currently working on a project for a company and i need to setup Drupal to work with Active Directory, i would like to know if this is possible and if so how i would go about implementing it. Basically what i would like to happen is when they sign in with there username and password to the computer it will recognize the sign in and adjust the name to say your name i.e. if im John and i login it will say John and if someone else login to the same computer using different username and password then it would say Matt.

Note that if possible i would like to use OpenAtrium as im developing a Intranet and need this functionality.

Drupal version:
