Samba 4 is the ambitious next version of the Samba suite that is being developed in parallel to the stable 3.0 series. The main emphasis in this branch is full support for being a Active Directory domain controller. Samba 4 is currently not yet in a state where it is usable in production environments. The STATUS file aims to document what should and should not work. Those familiar with Samba 3 can find a list of user-visible changes since that release series in the NEWS file. A short guide to setting up Samba 4 can be found in the howto.txt file in this directory. Bugs can be filed at https://bugzilla.samba.org/. Please look at the STATUS file before filing a bug to see if a particular is supposed to work yet. Development and general discussion about Samba 4 happens mainly on the #samba-technical IRC channel (on irc.freenode.net) and the samba-technical mailing list (see http://lists.samba.org/ for details).
