After being in development for nearly a decade, Samba 4.0 is finally in beta.
The Samba 4.0 Beta 1 arrived yesterday on the Phoronix birthday
with its multitude of changes that have been building up over the years. Back in January I mentioned Samba 4.0 was dancing closer to release
and finally we're to the beta milestone. This beta follows twenty-one alpha releases that were made of Samba 4.0.
The big item to Samba4 is support for the Microsoft Active Directory log-on protocols used by Windows 2000 and later while Samba's domain controller now includes its own built-in LDAP server and Kerberos Key Distribution Center, two distinct file servers, an NTVFS file server, and a new scripting interface.
More information on the Samba 4.0 Beta is available from the Samba.org Wiki
