Exploring Samba's new registry-based configuration
Samba's new registry-based configuration system conserves resources and lets the administrator configure entire clusters with a single command.
As most Linux users know, Samba  is an open source file and print system that provides interoperability with Windows environments. For more that 15 years, Samba has managed configuration settings through the plain-text file smb.conf. With the release of Samba 3.2.0 in July 2008, this paradigm of plain-text-only configuration is no longer the only option. A new configuration back end can store the configuration data in Samba's internal registry database. The default behavior is the same as before, but if you explicitly enable registry-based configuration through smb.conf, you can manage your Samba settings through a Windows-style registry.
Registry-based configuration opens many new options, such as remote administration and administration of Samba from Windows computers.
Why a Registry?
Samba has always maintained a registry database so that Windows clients could access the registry over the WINREG RPC interface to retrieve information for the connection. (Figure 1 shows WINREG access of a Windows client connecting to a Windows server.) Until recently, however, Samba did not use the registry for any other purposes.
