SMB/CIFS file, NT domain and active directory server (version 4)

 Samba is an implementation of the SMB/CIFS protocol for Unix systems,
 providing support for cross-platform file sharing with Microsoft Windows, OS X,
 and other Unix systems. Samba can also function as a domain controller
 or member server in both NT4-style and Active Directory domains.
 .
 These packages contain snapshot versions of Samba 4, the next-generation
 version of Samba. These should be considered _experimental_, and should
 not be used in production.
 .
 This package contains the main daemon.
