Samba is an open source implementation of the Server Message Block (SMB) protocol. It allows the networking of Microsoft Windows®, Linux, UNIX, and other operating systems together, enabling access to Windows-based file and printer shares. Samba's use of SMB allows it to appear as a Windows server to Windows clients.
The third major release of Samba, version 3.0.0, introduced numerous improvements from prior versions, including:
The ability to join an Active Directory domain by means of LDAP and Kerberos
Built in Unicode support for internationalization
Support for Microsoft Windows XP Professional client connections to Samba servers without needing local registry hacking
Two new documents developed by the Samba.org team, which include a 400+ page reference manual, and a 300+ page implementation and integration manual. For more information about these published titles, refer to Section 19.12.2, “Related Books”.
