The Oracle Solaris OS provides a Server Message Block (SMB) protocol server and client implementation that includes support for numerous SMB dialects including NT LM 0.12 and Common Internet File System (CIFS). The terms CIFS and SMB can be considered interchangeable.
The Solaris SMB server allows a native Oracle Solaris system to serve files as SMB shares to SMB enabled clients that mount the file system shares. A Windows, Mac OS, or Solaris client can interoperate with the Solaris SMB server as it would with a Windows server. A Solaris SMB server can operate in either workgroup mode or in domain mode. In workgroup mode, the Solaris SMB server is responsible for authenticating users locally when access is requested to shared resources. This authentication process is referred to as local login. In domain mode, the Solaris SMB server uses pass-through authentication, in which user authentication is delegated to a domain controller.
