-Readme for Samba 4
-==================
-
-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 support for the Active Directory logon protocols used
-by Windows 2000 and above.
-
-While we welcome your interest in Samba 4, we don't want you to run your
-network with it quite yet. Please note the WARNINGS below, and the
-STATUS file, which aims to document what should and should not work.
-
-With 4 years of development under our belt since Tridge first proposed
-a new Virtual File System (VFS) layer for Samba3 (a project which
-eventually lead to our Active Directory efforts), we felt that we
-should create something we could 'show off' to our users. This is a
-Technology Preview (TP), aimed at allowing you, our users, managers and
-developers to see how we have progressed, and to invite your feedback and
-support.
-
-Warnings
---------
-
-Samba4 is currently at alpha stage. That is more a reference to
-Samba4's lack of the features we expect you will need than a statement
-of code quality, but clearly it hasn't seen a broad deployment yet. If
-you were to upgrade Samba3 (or indeed Windows) to Samba4, you would find
-many things work, but that other key features you may have relied on
-simply are not there yet.
-
-For example, while Samba 3.0 is an excellent member of a Active
-Directory domain, Samba4 is happier as a domain controller: (This is
-where we have done most of the research and development).
-
-While Samba4 is subjected to an awesome battery of tests on an
-automated basis, and we have found Samba4 to be very stable in it's
-behaviour, we have to recommend against upgrading production servers
-from Samba 3 to Samba 4 at this stage. If you are upgrading an
-experimental server, or looking to develop and test Samba, you should
-backup all configuration and data.
-
-As we research the needs of Active Directory integration more closely,
-we may need to change the format of the user database, in particular
-as we begin to understand how the attributes are generated and stored.
-At a worst case, we expect users will be able to extract the stored
-data as LDIF and hand munge it, but until we make an alpha release, we
-won't do this automatically. Indeed, many module changes are simply
-easier to cope with if you just re-provision after the upgrade.
-
-We value the security of your computers, and so we must warn you that
-Samba 4 Technology Preview includes basic Access Control List (ACL)
-protection on the main user database, but due to time constraints,
-none on the registry at this stage. We also do not currently have
-ACLs on the SWAT web-based management tool. This means that Samba 4
-Technology Preview is not secure, and should not be exposed to
-untrusted networks.
-
-Within the above proviso, file system access should occur as the
-logged in user, much as Samba3 does.
-
-As such, we must strongly recommend against using Samba4 in a
-production environment at this stage.
-
-New Features
-------------
-
-Samba4 supports the server-side of the Active Directory logon environment
-used by Windows 2000 and later, so we can do full domain join
-and domain logon operations with these clients.
-
-Our Domain Controller (DC) implementation includes our own built-in
-LDAP server and Kerberos Key Distribution Centre (KDC) as well as the
-Samba3-like logon services provided over CIFS. We correctly generate
-the infamous Kerberos PAC, and include it with the Kerberos tickets we
-issue.
-
-SWAT is now integrated into Samba 4 as the user-friendly interface to
-Samba server management. SWAT provides easy access to our
-setup and migration tools. Using SWAT, you can migrate windows
-domains in Samba 4, allowing easy setup of initial user databases, and
-upgrades from Samba 3.
-
-The new VFS features in Samba 4 adapts the file-system on the server to
-match the Windows client semantics, allowing Samba 4 to better match
-windows behaviour and application expectations. This includes file
-annotation information (in streams) and NT ACLs in particular. The
-VFS is backed with an extensive automated test suite.
-
-A new scripting interface has been added to Samba 4, allowing
-JavaScript programs to interface to Samba's internals.
-
-The Samba 4 architecture is based around an LDAP-like database that
-can use a range of modular backends. One of the backends supports
-standards compliant LDAP servers (including OpenLDAP), and we are
-working on modules to map between AD-like behaviours and this back-end.
-We are aiming for Samba 4 to be powerful front-end to large
-directories.
-
-Changes
--------
-
-Those familiar with Samba 3 can find a list of user-visible changes
-since that release series in the NEWS file.
-
-- An optional password is no longer supported as the second argument to
- smbclient.
-
-- The default location of smb.conf in non-FHS builds has changed from the
- PREFIX/lib directory to the PREFIX/etc directory.
-
-Known issues
-------------
-
-- Standalone server and domain member roles are not currently
- supported. While we have much of the infrastructure required, we
- have not collected these pieces together.
-
-- There is no printing support in the current release.
-
-- SWAT can be painful with <TAB> and forms. Just use the mouse, as
- the JavaScript layer doing this will change.
-
-Running Samba4
---------------
-
-A short guide to setting up Samba 4 can be found in the howto.txt file
-in root of the tarball.
-
-Development and feedback
-------------------------
-
-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).
