The main emphasis in +this branch is support for the Active Directory logon protocols used +by Windows 2000 and above. + +Samba 4 is currently not yet in a state where it is usable in +production environments. Note the WARNINGS below, and the STATUS file, +which aims to document what should and should not work. + +Samba4 alpha1 is the culmination of 4.5 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), and 1.5 years since we first released a Technology Preview, +we wish to allow users, managers and developers to see how we have +progressed, and to invite feedback and support. + +WARNINGS +======== + +Samba4 alpha1 is not a final Samba release. We recommend against +upgrading any production servers from Samba 3 to Samba 4 at this +stage. If you are upgrading an experimental server, you should backup +all configuration and data. + +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 Center (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 provides access to our +setup and migration tools. Using SWAT, you can migrate windows +domains in Samba 4, allowing easy setup of initial user databases. + +The new VFS features in Samba 4 adapts the filesystem 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 backend. +We are aiming for Samba 4 to be powerful frontend to large +directories. + +CHANGES SINCE TP5 +================= In the time since TP5 was released in June 2007, Samba has continued to evolve, but you may particularly notice these areas: @@ -24,4 +84,42 @@ These are just some of the highlights of the work done in the past few months.
