    Hello

    Currently all of our DC's (5 of them) are running Windows 2008. The DC's
    have been running windows 2008 for a year now. The domain and forest
    functional levels however are still at 2003 native. I would like to raise
    the DFL and FFL to 2008, but before I do this I want to understand if
    raising the levels changes the way that AD does it authentication or
    authorization? If all DC's are already running 2008, then raising the DFL
    and FFL shouldn't create any changes that haven't already been introduced
    when all DC's were upgraded to 2008.


    We have appliances like Datadomain Netapp SANS Cisco radius call manager.
    None of these appliances have experienced issues authenticating to a windows
    2008 DC

    thanks

  2. Hello Sawyer,

    Raising the functional level will not change the way how authentication works,
    it gives you additional options, see here about:
