SAMBA and upgrading from Windows 2000 interim mode to 2003 nativemode

    I currently have two Windows 2003 AD servers, that are configured as
    'Windows 2000 interim' mode. A number of *nix clients are
    authenticating to these servers via Samba 3.x.

    I want to bring the domain up to Windows 2003 native mode, but am
    concerned about what this might do to the ability for the *nix machines
    to authenticate against AD once this change happens.

    Does anyone know the gotchas of going from Windows 2000 interim mode, to
    Windows 2003 native mode and the effect it has on Samba client
    authentication?

    You are talking about:
    Domain Functional Level
    Forest Functional Level

    In either case, this has nothing to do with clients authenticating on these
    domain controllers. It is important for domain controllers' replication
    process (how DC's talk to each other).

    In Interim Domain Functional level, you can have only Windows NT and Windows
    2003 DC's (and any other kind of clients). This is special mode when you
    transition from NT to Win 2003. When you get rid of all Windows NT DC's
    (*DC's*, not clients, like NT Workstations and NT member servers), then you
    can raise Domain and forest functional levels to Win 2003.

    In either case, after you raise domain or forest functional level your SAMBA
    will not be affected, it will continue to work as before.

    This was exactly the information I was looking for. None of the DCs
    are anything less than Windows 2003, which is why I was surprised to see
    the domain configured for 2000 interim mode. My main concern was the
    SMB authentication.

    Thanks again!
