Learn Linux, 302 (Mixed environments): CIFS integration
In addition to, or instead of, functioning as a server on a Windows network, a Linux computer can function as a client. You can use an ftp-like program to transfer files and modify a server, or you can mount a share from a Samba or Windows Server machine on your Linux computer, giving normal programs the ability to access files directly on the server. When doing so, though, keep in mind the characteristics of the original SMB protocol and its newer CIFS variant, particularly when accessing a Windows Server machine: You may not have access to all the file system features that a Linux computer supports.

Learn Linux, 302 (Mixed environments): Domain control
In SMB/CIFS parlance, a domain is similar to a workgroup: It's a collection of related computers, typically existing on a single local network. A domain, however, features a special computer known as a domain controller that manages logons for all the servers in the domain. It also provides a few additional services. Samba can function as a domain controller, but you need to set several Samba options for it to do so.

Learn Linux, 302 (Mixed environments): Install and upgrade Samba
Like most software, Samba must be installed before it can be used. Several methods of doing this exist, but they fall into two broad categories: compiling and installing from source code and installing pre-built binary packages. The former is the more difficult but also more flexible option, while the latter is quite easy on most Linux distributions but locks you into the decisions your distribution maintainer has made concerning supported versions, patches applied, compile-time options enabled, and so on.

Learn Linux, 302 (Mixed environments): Integration with Active Directory
Since the release of Windows 2000, Microsoft has offered Active Directory as its directory service, and later versions have renamed it Active Directory Domain Services (AD DS). AD DS leverages the popular LDAP for resource management, Kerberos for authentication, and tight integration with DNS for name resolution. If you currently use AD DS, integrating a Linux server can help centralize identity management and maintenance for Linux printing and file services. However, doing so can be challenging. Fortunately, Samba provides a solution for Linux integration with AD DS that requires no modification to the directory service. [Note: We corrected the Listing 4 caption and clarified the section on "Using the net command" per reader feedback.]

Learn Linux, 302 (Mixed environments): NetBIOS and WINS
Naming is unusual in SMB/CIFS networks. Although modern clients can use Internet domain names to refer to each other, older clients relied on a Microsoft-specific system known as the Windows Internet Name Service (WINS) server, or the NetBIOS Name Server (NBNS); the two terms are synonymous. Configuring Samba properly for name resolution is therefore important. So is configuring browsing, which is the mechanism by which servers learn what shares are available on specific servers.

Learn Linux, 302 (Mixed environments): Samba roles
Samba isn't a single program; rather, it's a series of interrelated servers and utilities, each of which has its own specific purpose. Understanding the differences between these servers and utilities will help you manage your Samba system. Furthermore, Samba implements a number of different security models, which you must understand to properly integrate Samba into an existing network or to set up a new network with Samba servers at its core.

Learn Linux, 302 (Mixed environments): Winbind
If your network includes a domain controller (either a Windows computer or a Samba server), you can use its user database instead of or in addition to maintaining local login users in a Linux computer's local account database. Doing so requires using a set of tools known as Winbind. This toolset can be handy even for Linux computers that don't run Samba to share files or printers; users with Windows domain accounts can log in at the console or use SSH to access Linux-only features, use POP or IMAP mail servers with Windows domain authentication, and so on.
