Active Directory Integration in 3 Hours or Less

Hey folks, This is the most complete process I have read up to date on how to get this accomplished. What still seems to be missing from my knowledge base are the steps needed to set the login window to interact with AD server. I believe that my schema is set up correctly but when I run the lookupd -d command line and allUsers It is just returning the local account information. Is there something I need to set up in the netinfo service (like log onto a domain at start up) or is there a logon script that needs to be created/modified in order to interact with the network? I am able to ping my servers and smb into network resources. Any help would be greatly appreciated.
