You can't login to SAP with the AD user name and password unless you build synchronization between AD and SAP. Instead you should look into solutions which are based on user already having authenticated to Windows with AD credentials and then enabling automatic access to SAP based on the already existing Windows authentication. If your requirement is to force login to SAP with AD username and password although already authenticated to Windows, I suggest you look into implementing Secure Login Client of NetWeaver Single Sign-On. It can be configured to request the user to authenticate with AD user name and password.
