In many +cases a stand-alone server is configured with a minimum of security control +with the intent that all data served will be readily accessible to all users. +</p><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2893079"></a>Features and Benefits</h2></div></div><div></div></div><p> +Stand-Alone servers can be as secure or as insecure as needs dictate. They can +have simple or complex configurations. Above all, despite the hoopla about +Domain security they remain a very common installation. +</p><p> +If all that is needed is a server for read-only files, or for +printers alone, it may not make sense to affect a complex installation. +For example: A drafting office needs to store old drawings and reference +standards. No-one can write files to the server as it is legislatively +important that all documents remain unaltered. A share mode read-only stand-alone +server is an ideal solution. +</p><p> +Another situation that warrants simplicity is an office that has many printers +that are queued off a single central server. Everyone needs to be able to print +to the printers, there is no need to affect any access controls and no files will +be served from the print server. Again a share mode stand-alone server makes +a great solution. +</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2893117"></a>Background</h2></div></div><div></div></div><p> +The term <span class="emphasis"><em>stand-alone server</em></span> means that the server +will provide local authentication and access control for all resources +that are available from it. In general this means that there will be a +local user database. In more technical terms, it means that resources +on the machine will be made available in either SHARE mode or in +USER mode. +</p><p> +No special action is needed other than to create user accounts. Stand-alone +servers do NOT provide network logon services. This means that machines that +use this server do NOT perform a domain logon to it. Whatever logon facility +the workstations are subject to is independent of this machine. It is however +necessary to accommodate any network user so that the logon name they use will +be translated (mapped) locally on the stand-alone server to a locally known +user name. There are several ways this can be done. +</p><p> +Samba tends to blur the distinction a little in respect of what is +a stand-alone server. This is because the authentication database may be +local or on a remote server, even if from the Samba protocol perspective +the Samba server is NOT a member of a domain security context. +</p><p> +Through the use of PAM (Pluggable Authentication Modules) and nsswitch +(the name service switcher, which maintains the unix user database) the source of authentication may reside on +another server. We would be inclined to call this the authentication server. +This means that the Samba server may use the local UNIX/Linux system password database +(<tt class="filename">/etc/passwd</tt> or <tt class="filename">/etc/shadow</tt>), may use a +local smbpasswd file, or may use +an LDAP back end, or even via PAM and Winbind another CIFS/SMB server +for authentication. +</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2893191"></a>Example Configuration</h2></div></div><div></div></div><p> +The following examples are designed to inspire simplicity.

Assume that all the reference documents +are stored in the directory /export, that the documents are owned by a user other than +nobody. No home directories are shared, that are no users in the <tt class="filename">/etc/passwd</tt> +UNIX system database. This is a very simple system to administer. +</p><div class="example"><a name="id2893237"></a><p class="title"><b>Example 8.1. smb.conf for Reference Documentation Server</b></p><table class="simplelist" border="0" summary="Simple list"><tr><td># Global parameters</td></tr><tr><td> </td></tr><tr><td><i class="parameter"><tt>[global]</tt></i></td></tr><tr><td><i class="parameter"><tt>workgroup = MIDEARTH</tt></i></td></tr><tr><td><i class="parameter"><tt>netbios name = GANDALF</tt></i></td></tr><tr><td><i class="parameter"><tt>security = SHARE</tt></i></td></tr><tr><td><i class="parameter"><tt>passdb backend = guest</tt></i></td></tr><tr><td><i class="parameter"><tt>wins server = 192.168.1.1</tt></i></td></tr><tr><td> </td></tr><tr><td><i class="parameter"><tt>[data]</tt></i></td></tr><tr><td><i class="parameter"><tt>comment = Data</tt></i></td></tr><tr><td><i class="parameter"><tt>path = /export</tt></i></td></tr><tr><td><i class="parameter"><tt>guest only = Yes</tt></i></td></tr></table></div><p> +In the above example the machine name is set to REFDOCS, the workgroup is set to the name +of the local workgroup so that the machine will appear in with systems users are familiar +with.
