Authentication of a user using Active Directory

Hi;

I'm an undergraduate student doing my final year project as part of my work I'm creating a Virtual Learning Environment. However I will require my users to log in using user names and passwords from a windows active directory. The big problem is i dont have any idea how to do it. Can anyone help?

Many Thanks
