8 <title>Fast Start: Cure for Impatience</title>
10 <para>
11 When we first asked for suggestions for inclusion in the Samba HOWTO documentation,
12 someone wrote asking for example configurations &smbmdash; and lots of them. That is remarkably
13 difficult to do without losing a lot of value that can be derived from presenting
14 many extracts from working systems. That is what the rest of this document does.
15 It does so with extensive descriptions of the configuration possibilities within the
16 context of the chapter that covers it. We hope that this chapter is the medicine
17 that has been requested.
18 </para>
20 <para>
21 The information in this chapter is very sparse compared with the book <quote>Samba-3 by Example</quote>
22 that was written after the original version of this book was nearly complete. <quote>Samba-3 by Example</quote>
23 was the result of feedback from reviewers during the final copy editing of the first edition. It
24 was interesting to see that reader feedback mirrored that given by the original reviewers.
25 In any case, a month and a half was spent in doing basic research to better understand what
26 new as well as experienced network administrators would best benefit from. The book <quote>Samba-3 by Example</quote>
27 is the result of that research. What is presented in the few pages of this book is covered
28 far more comprehensively in the second edition of <quote>Samba-3 by Example</quote>. The second edition
29 of both books will be released at the same time.
30 </para>
32 <para>
33 So in summary, the book <quote>The Official Samba-3 HOWTO & Reference Guide</quote> is intended
34 as the equivalent of an auto mechanic's repair guide. The book <quote>Samba-3 by Example</quote> is the
35 equivalent of the driver's guide that explains how to drive the car. If you want complete network
36 configuration examples, go to <ulink url="http://www.samba.org/samba/docs/Samba3-ByExample.pdf">Samba-3 by

41 <title>Features and Benefits</title>
43 <para>
44 Samba needs very little configuration to create a basic working system.
45 In this chapter we progress from the simple to the complex, for each providing
46 all steps and configuration file changes needed to make each work. Please note
47 that a comprehensively configured system will likely employ additional smart
48 features. These additional features are covered in the remainder of this document.
49 </para>
51 <para>
52 The examples used here have been obtained from a number of people who made
53 requests for example configurations. All identities have been obscured to protect
54 the guilty, and any resemblance to unreal nonexistent sites is deliberate.

60 <title>Description of Example Sites</title>
62 <para>
63 In the first set of configuration examples we consider the case of exceptionally simple system requirements.
64 There is a real temptation to make something that should require little effort much too complex.
65 </para>
67 <para>
68 <link linkend="anon-ro"></link> documents the type of server that might be sufficient to serve CD-ROM images,
69 or reference document files for network client use. This configuration is also discussed in <link
70 linkend="StandAloneServer"></link>, <link linkend="RefDocServer"></link>. The purpose for this configuration
71 is to provide a shared volume that is read-only that anyone, even guests, can access.
72 </para>
74 <para>
75 The second example shows a minimal configuration for a print server that anyone can print to as long as they
76 have the correct printer drivers installed on their computer. This is a mirror of the system described in
77 <link linkend="StandAloneServer"></link>, <link linkend="SimplePrintServer"></link>.
78 </para>
80 <para>
81 The next example is of a secure office file and print server that will be accessible only to users who have an
82 account on the system. This server is meant to closely resemble a workgroup file and print server, but has to
83 be more secure than an anonymous access machine. This type of system will typically suit the needs of a small
84 office. The server provides no network logon facilities, offers no domain control; instead it is just a
85 network-attached storage (NAS) device and a print server.
86 </para>
88 <para>
89 The later example consider more complex systems that will either integrate into existing MS Windows networks
90 or replace them entirely. These cover domain member servers as well as Samba domain control (PDC/BDC) and
91 finally describes in detail a large distributed network with branch offices in remote locations.
92 </para>

97 <title>Worked Examples</title>
99 <para>
100 The configuration examples are designed to cover everything necessary to get Samba
101 running. They do not cover basic operating system platform configuration, which is
102 clearly beyond the scope of this text.
103 </para>
105 <para>
106 It is also assumed that Samba has been correctly installed, either by way of installation
107 of the packages that are provided by the operating system vendor or through other means.

111 <title>Standalone Server</title>
113 <para>
114 <indexterm><primary>Server Type</primary><secondary>Stand-alone</secondary></indexterm>
115 A standalone server implies no more than the fact that it is not a domain controller
116 and it does not participate in domain control. It can be a simple, workgroup-like
117 server, or it can be a complex server that is a member of a domain security context.
118 </para>
120 <para>
121 As the examples are developed, every attempt is made to progress the system toward greater capability, just as
122 one might expect would happen in a real business office as that office grows in size and its needs change.

126 <title>Anonymous Read-Only Document Server</title>
128 <para>

130 The purpose of this type of server is to make available to any user
131 any documents or files that are placed on the shared resource. The
132 shared resource could be a CD-ROM drive, a CD-ROM image, or a file
133 storage area.

264 We should view this configuration as a progression from the previous example.
265 The difference is that shared access is now forced to the user identity of jackb
266 and to the primary group jackb belongs to. One other refinement we can make is to
267 add the user <emphasis>jackb</emphasis> to the <filename>smbpasswd</filename> file.
268 To do this, execute:
269 <screen>
270 &rootprompt;<userinput>smbpasswd -a jackb</userinput>
271 New SMB password: <userinput>m0r3pa1n</userinput>
272 Retype new SMB password: <userinput>m0r3pa1n</userinput>
273 Added user jackb.

275 Addition of this user to the <filename>smbpasswd</filename> file allows all files

325 <para>
326 In the simplest of anonymous print servers, it is common to require the installation
327 of the correct printer drivers on the Windows workstation. In this case the print
328 server will be designed to just pass print jobs through to the spooler, and the spooler
329 should be configured to do raw pass-through to the printer. In other words, the print
330 spooler should not filter or process the data stream being passed to the printer.

334 In this configuration, it is undesirable to present the Add Printer Wizard, and we do

360 The above configuration is not ideal. It uses no smart features, and it deliberately
361 presents a less than elegant solution. But it is basic, and it does print. Samba makes
362 use of the direct printing application program interface that is provided by CUPS.
363 When Samba has been compiled and linked with the CUPS libraries, the default printing
364 system will be CUPS. By specifying that the printcap name is CUPS, Samba will use
365 the CUPS library API to communicate directly with CUPS for all printer functions.
366 It is possible to force the use of external printing commands by setting the value
367 of the <parameter>printing</parameter> to either SYSV or BSD, and thus the value of
368 the parameter <parameter>printcap name</parameter> must be set to something other than
369 CUPS. In such case, it could be set to the name of any file that contains a list
370 of printers that should be made available to Windows clients.
371 </para>
373 <note><para>
374 Windows users will need to install a local printer and then change the print

407 On CUPS-enabled systems there is a facility to pass raw data directly to the printer without
408 intermediate processing via CUPS print filters. Where use of this mode of operation is desired,
409 it is necessary to configure a raw printing device. It is also necessary to enable the raw mime

610 By now you should be getting the hang of configuration basics. Clearly, it is time to

624 In this instance we consider the simplest server configuration we can get away with
625 to make an accounting department happy. Let's be warned, the users are accountants and they
626 do have some nasty demands. There is a budget for only one server for this department.
627 </para>
629 <para>
630 The network is managed by an internal Information Services Group (ISG), to which we belong.
631 Internal politics are typical of a medium-sized organization; Human Resources is of the
632 opinion that they run the ISG because they are always adding and disabling users. Also,
633 departmental managers have to fight tooth and nail to gain basic network resources access for
634 their staff. Accounting is different, though, they get exactly what they want. So this should
635 set the scene.
636 </para>
638 <para>
639 We use the users from the last example. The accounting department
640 has a general printer that all departmental users may use. There is also a check printer
641 that may be used only by the person who has authority to print checks. The chief financial
642 officer (CFO) wants that printer to be completely restricted and for it to be located in the
643 private storage area in her office. It therefore must be a network printer.
644 </para>
646 <para>
647 The accounting department uses an accounting application called <emphasis>SpytFull</emphasis>
648 that must be run from a central application server. The software is licensed to run only off
649 one server, there are no workstation components, and it is run off a mapped share. The data
650 store is in a UNIX-based SQL backend. The UNIX gurus look after that, so this is not our
651 problem.
652 </para>
654 <para>
655 The accounting department manager (maryo) wants a general filing system as well as a separate
656 file storage area for form letters (nastygrams). The form letter area should be read-only to
657 all accounting staff except the manager. The general filing system has to have a structured
658 layout with a general area for all staff to store general documents as well as a separate
659 file area for each member of her team that is private to that person, but she wants full
660 access to all areas. Users must have a private home share for personal work-related files
661 and for materials not related to departmental operations.

843 For the remainder of this chapter the focus is on the configuration of domain control.
844 The examples that follow are for two implementation strategies. Remember, our objective is
845 to create a simple but working solution. The remainder of this book should help to highlight
846 opportunity for greater functionality and the complexity that goes with it.
847 </para>
849 <para>
850 A domain controller configuration can be achieved with a simple configuration using the new
851 tdbsam password backend. This type of configuration is good for small
852 offices, but has limited scalability (cannot be replicated), and performance can be expected
853 to fall as the size and complexity of the domain increases.
854 </para>
856 <para>
857 The use of tdbsam is best limited to sites that do not need
858 more than a Primary Domain Controller (PDC). As the size of a domain grows the need
859 for additional domain controllers becomes apparent. Do not attempt to under-resource
860 a Microsoft Windows network environment; domain controllers provide essential
861 authentication services. The following are symptoms of an under-resourced domain control
862 environment:

874 </itemizedlist>
876 <para>
877 A more scalable domain control authentication backend option might use
878 Microsoft Active Directory or an LDAP-based backend. Samba-3 provides
879 for both options as a domain member server. As a PDC, Samba-3 is not able to provide
880 an exact alternative to the functionality that is available with Active Directory.
881 Samba-3 can provide a scalable LDAP-based PDC/BDC solution.
882 </para>
884 <para>
885 The tdbsam authentication backend provides no facility to replicate
886 the contents of the database, except by external means (i.e., there is no self-contained protocol
887 in Samba-3 for Security Account Manager database [SAM] replication).
888 </para>
890 <note><para>
891 If you need more than one domain controller, do not use a tdbsam authentication backend.

899 of the new tdbsam password backend. The tdbsam
900 facility is new to Samba-3. It is designed to provide many user and machine account controls
