Web forms & OID

Hi
we are going to deploy Oracle FORMS/REPORTS web application in ORACLE 9iAS rel 2 and database is 9iR2.
we would like to configure oracle internet directory for accessing oracle forms.
(i.e) Web application (authentication) is done only by Oracle Internet dorectory(OID).we have windows 2000 clients and each client has got username /password.
How do i configure windows 2000 username/password to access oracle web application and database.Anybody have steps or document that will be helpful to us.
