3 Roaming profiles are feared by some, hated by a few, loved by many, and a godsend for
4 some administrators.
5 </p><p>
7 Roaming profiles allow an administrator to make available a consistent user desktop
8 as the user moves from one machine to another. This chapter provides much information
9 regarding how to configure and manage roaming profiles.
10 </p><p>
12 While roaming profiles might sound like nirvana to some, they are a real and tangible
13 problem to others. In particular, users of mobile computing tools, where often there may not
14 be a sustained network connection, are often better served by purely local profiles.
15 This chapter provides information to help the Samba administrator deal with those
16 situations.
17 </p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id417955"></a>Roaming Profiles</h2></div></div></div><div class="warning" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Warning</h3><p>
19 </p></div><p>
20 Before discussing how to configure roaming profiles, it is useful to see how
22 </p><p>
24 Windows 9x/Me clients send a NetUserGetInfo request to the server to get the user's
25 profiles location. However, the response does not have room for a separate
26 profiles location field, only the user's home share. This means that Windows 9x/Me
27 profiles are restricted to being stored in the user's home directory.
28 </p><p>
31 Windows NT4/200x clients send a NetSAMLogon RPC request, which contains many fields
32 including a separate field for the location of the user's profiles.
33 </p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id418003"></a>Samba Configuration for Profile Handling</h3></div></div></div><p>
34 This section documents how to configure Samba for MS Windows client profile support.
35 </p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id418013"></a>NT4/200x User Profiles</h4></div></div></div><p>
36 For example, to support Windows NT4/200x clients, set the following in the [global] section of the <code class="filename">smb.conf</code> file:
37 </p><table class="simplelist" border="0" summary="Simple list"><tr><td><a class="indexterm" name="id418034"></a><em class="parameter"><code>logon path = \\profileserver\profileshare\profilepath\%U\moreprofilepath</code></em></td></tr></table><p>
38 This is typically implemented like:
39 </p><table class="simplelist" border="0" summary="Simple list"><tr><td><a class="indexterm" name="id418055"></a><em class="parameter"><code>logon path = \\%L\Profiles\%U</code></em></td></tr></table><p>
40 where “<span class="quote">%L</span>” translates to the name of the Samba server and “<span class="quote">%U</span>” translates to the username.
41 </p><p>
42 The default for this option is <code class="filename">\\%N\%U\profile</code>, namely, <code class="filename">\\sambaserver\username\profile</code>.
43 The <code class="filename">\\%N\%U</code> service is created automatically by the [homes] service. If you are using
44 a Samba server for the profiles, you must make the share that is specified in the logon path
45 browseable. Please refer to the man page for <code class="filename">smb.conf</code> regarding the different
46 semantics of “<span class="quote">%L</span>” and “<span class="quote">%N</span>”, as well as “<span class="quote">%U</span>” and “<span class="quote">%u</span>”.
47 </p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
50 MS Windows NT/200x clients at times do not disconnect a connection to a server between logons. It is recommended
51 to not use the <em class="parameter"><code>homes</code></em> metaservice name as part of the profile share path.
52 </p></div></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id418146"></a>Windows 9x/Me User Profiles</h4></div></div></div><p>
55 To support Windows 9x/Me clients, you must use the <a class="indexterm" name="id418168"></a>logon home
56 parameter. Samba has been fixed so <strong class="userinput"><code>net use /home</code></strong> now works as well and it, too, relies
58 </p><p>
62 By using the <em class="parameter"><code>logon home</code></em> parameter, you are restricted to putting Windows 9x/Me profiles
63 in the user's home directory. But wait! There is a trick you can use. If you set the following in the
64 <em class="parameter"><code>[global]</code></em> section of your <code class="filename">smb.conf</code> file:
65 </p><table class="simplelist" border="0" summary="Simple list"><tr><td><a class="indexterm" name="id418236"></a><em class="parameter"><code>logon home = \\%L\%U\.profiles</code></em></td></tr></table><p>
66 then your Windows 9x/Me clients will dutifully put their clients in a subdirectory
68 </p><p>
70 Not only that, but <strong class="userinput"><code>net use /home</code></strong> will also work because of a feature in
71 Windows 9x/Me. It removes any directory stuff off the end of the home directory area
72 and only uses the server and share portion. That is, it looks like you
73 specified <code class="filename">\\%L\%U</code> for <a class="indexterm" name="id418280"></a>logon home.
74 </p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id418289"></a>Mixed Windows Windows 9x/Me and NT4/200x User Profiles</h4></div></div></div><p>
75 You can support profiles for Windows 9x and Windows NT clients by setting both the
76 <a class="indexterm" name="id418298"></a>logon home and <a class="indexterm" name="id418305"></a>logon path parameters. For example,
77 </p><table class="simplelist" border="0" summary="Simple list"><tr><td><a class="indexterm" name="id418319"></a><em class="parameter"><code>logon home = \\%L\%U\.profiles</code></em></td></tr><tr><td><a class="indexterm" name="id418332"></a><em class="parameter"><code>logon path = \\%L\profiles\%U</code></em></td></tr></table><p>
79 Windows 9x/Me and NT4 and later profiles should not be stored in the same location because
80 Windows NT4 and later will experience problems with mixed profile environments.
81 </p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id418357"></a>Disabling Roaming Profile Support</h4></div></div></div><p>
83 The question often asked is, “<span class="quote">How may I enforce use of local profiles?</span>” or
85 </p><p>
87 There are three ways of doing this:
88 </p><a class="indexterm" name="id418392"></a><div class="variablelist"><dl><dt><span class="term">In <code class="filename">smb.conf</code></span></dt><dd><p>
89 Affect the following settings and ALL clients will be forced to use a local profile:
90 <a class="indexterm" name="id418418"></a>logon home = and <a class="indexterm" name="id418425"></a>logon path =
91 </p><p>
92 The arguments to these parameters must be left blank. It is necessary to include the <code class="constant">=</code> sign
93 to specifically assign the empty value.
97 Use the Microsoft Management Console (MMC) <code class="literal">gpedit.msc</code> to instruct your MS Windows XP
98 machine to use only a local profile. This, of course, modifies registry settings. The full
99 path to the option is:

118 </p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
120 The specifics of how to convert a local profile to a roaming profile, or a roaming profile
121 to a local one, vary according to the version of MS Windows you are running. Consult the Microsoft MS
122 Windows Resource Kit for your version of Windows for specific information.

124 When a user first logs in on Windows 9x, the file user.DAT is created, as are folders <code class="filename">Start
126 <code class="filename">Nethood</code>. These directories and their contents will be merged with the local versions
127 stored in <code class="filename">c:\windows\profiles\username</code> on subsequent logins, taking the most recent from
128 each. You will need to use the <em class="parameter"><code>[global]</code></em> options <a class="indexterm" name="id418608"></a>preserve case = yes, <a class="indexterm" name="id418615"></a>short preserve case = yes, and <a class="indexterm" name="id418622"></a>case sensitive = no in order to maintain capital letters in shortcuts in any of the
129 profile folders.
130 </p><p>
133 The <code class="filename">user.DAT</code> file contains all the user's preferences. If you wish to enforce a set of preferences,
134 rename their <code class="filename">user.DAT</code> file to <code class="filename">user.MAN</code>, and deny them write access to this file.
137 <span class="guimenuitem">Passwords</span> and select the <span class="guilabel">User Profiles</span> tab.
138 Select the required level of roaming preferences. Press <span class="guibutton">OK</span>, but do not
139 allow the computer to reboot.
140 </p></li><li><p>
142 <span class="guimenuitem">Network</span> -> <span class="guimenuitem">Client for Microsoft Networks</span>
143 -> <span class="guilabel">Preferences</span>. Select <span class="guilabel">Log on to NT Domain</span>. Then,
144 ensure that the Primary Logon is <span class="guilabel">Client for Microsoft Networks</span>. Press
146 </p></li></ol></div><p>
151 Under Windows 9x/Me, profiles are downloaded from the Primary Logon. If you have the Primary Logon
152 as “<span class="quote">Client for Novell Networks</span>”, then the profiles and logon script will be downloaded from
153 your Novell server. If you have the Primary Logon as “<span class="quote">Windows Logon</span>”, then the profiles will
154 be loaded from the local machine a bit against the concept of roaming profiles, it would seem!
155 </p><p>
157 You will now find that the Microsoft Networks Login box contains <code class="constant">[user, password, domain]</code> instead
158 of just <code class="constant">[user, password]</code>. Type in the Samba server's domain name (or any other domain known to exist,
159 but bear in mind that the user will be authenticated against this domain and profiles downloaded from it
160 if that domain logon server supports it), user name and user's password.
161 </p><p>
162 Once the user has been successfully validated, the Windows 9x/Me machine informs you that
163 <code class="computeroutput">The user has not logged on before</code> and asks <code class="computeroutput">Do you
165 </p><p>
166 Once the Windows 9x/Me client comes up with the desktop, you should be able to examine the
167 contents of the directory specified in the <a class="indexterm" name="id418844"></a>logon path on
168 the Samba server and verify that the <code class="filename">Desktop</code>, <code class="filename">Start Menu</code>,
169 <code class="filename">Programs</code>, and <code class="filename">Nethood</code> folders have been created.
170 </p><p>
174 These folders will be cached locally on the client and updated when the user logs off (if
175 you haven't made them read-only by then). You will find that if the user creates further folders or
176 shortcuts, the client will merge the profile contents downloaded with the contents of the profile
177 directory already on the local client, taking the newest folders and shortcut from each set.
178 </p><p>
183 If you have made the folders/files read-only on the Samba server, then you will get errors from
184 the Windows 9x/Me machine on logon and logout as it attempts to merge the local and remote profile.
185 Basically, if you have any errors reported by the Windows 9x/Me machine, check the UNIX file permissions
186 and ownership rights on the profile directory contents, on the Samba server.
187 </p><p>
193 If you have problems creating user profiles, you can reset the user's local desktop cache, as shown below.
194 When this user next logs in, the user will be told that he/she is logging in “<span class="quote">for the first
197 Instead of logging in under the [user, password, domain] dialog, press <span class="guibutton">escape</span>.

215 file for the user, making a backup if required.
216 </p></li></ol></div><div class="warning" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Warning</h3><p>
218 Before deleting the contents of the directory listed in the <em class="parameter"><code>ProfilePath</code></em>
219 (this is likely to be <code class="filename">c:\windows\profiles\username)</code>, ask whether the owner has
220 any important files stored on his or her desktop or start menu. Delete the contents of the
221 directory <em class="parameter"><code>ProfilePath</code></em> (making a backup if any of the files are needed).
222 </p><p>
223 This will have the effect of removing the local (read-only hidden system file) <code class="filename">user.DAT</code>
224 in their profile directory, as well as the local “<span class="quote">desktop,</span>” “<span class="quote">nethood,</span>”
225 “<span class="quote">start menu,</span>” and “<span class="quote">programs</span>” folders.

236 If you have access to an Windows NT4/200x server, then first set up roaming profiles and/or
237 netlogons on the Windows NT4/200x server. Make a packet trace, or examine the example packet traces
238 provided with Windows NT4/200x server, and see what the differences are with the equivalent Samba trace.
239 </p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id419197"></a>Windows NT4 Workstation</h4></div></div></div><p>
240 When a user first logs in to a Windows NT workstation, the profile NTuser.DAT is created. The profile
241 location can be now specified through the <a class="indexterm" name="id419206"></a>logon path parameter.
242 </p><p>
243 There is a parameter that is now available for use with NT Profiles: <a class="indexterm" name="id419217"></a>logon drive.
244 This should be set to <code class="filename">H:</code> or any other drive, and should be used in conjunction with
246 </p><p>
249 The entry for the NT4 profile is a directory, not a file. The NT help on profiles mentions that a
250 directory is also created with a .PDS extension. The user, while logging in, must have write permission
251 to create the full profile path (and the folder with the .PDS extension for those situations where it
252 might be created).
253 </p><p>
255 In the profile directory, Windows NT4 creates more folders than Windows 9x/Me. It creates
256 <code class="filename">Application Data</code> and others, as well as <code class="filename">Desktop</code>,
257 <code class="filename">Nethood</code>, <code class="filename">Start Menu,</code> and <code class="filename">Programs</code>.
258 The profile itself is stored in a file <code class="filename">NTuser.DAT</code>. Nothing appears to be stored
259 in the .PDS directory, and its purpose is currently unknown.
260 </p><p>
263 You can use the <span class="application">System Control Panel</span> to copy a local profile onto
264 a Samba server (see NT help on profiles; it is also capable of firing up the correct location in the
265 <span class="application">System Control Panel</span> for you). The NT help file also mentions that renaming
266 <code class="filename">NTuser.DAT</code> to <code class="filename">NTuser.MAN</code> turns a profile into a mandatory one.
267 </p><p>
268 The case of the profile is significant. The file must be called <code class="filename">NTuser.DAT</code>
270 </p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id419365"></a>Windows 2000/XP Professional</h4></div></div></div><p>
271 You must first convert the profile from a local profile to a domain profile on the MS Windows
272 workstation as follows: </p><div class="procedure"><ol type="1"><li><p> Log on as the <span class="emphasis"><em>local</em></span> workstation administrator. </p></li><li><p> Right-click on the <span class="guiicon">My Computer</span> icon, and select

278 you nominated. </p></li></ol></div><p>
279 Done. You now have a profile that can be edited using the Samba <code class="literal">profiles</code> tool.
280 </p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
281 Under Windows NT/200x, the use of mandatory profiles forces the use of MS Exchange storage of mail
282 data and keeps it out of the desktop profile. That keeps desktop profiles from becoming unusable.

300 There are certain situations that cause a cached local copy of roaming profile not to be deleted on exit, even if
301 the policy to force such deletion is set. To deal with that situation, a special service was created. The application
302 <code class="literal">UPHClean</code> (User Profile Hive Cleanup) can be installed as a service on Windows NT4/2000/XP Professional
303 and Windows 2003.

311 Sharing of desktop profiles between Windows versions is not recommended. Desktop profiles are an
312 evolving phenomenon, and profiles for later versions of MS Windows clients add features that may interfere
313 with earlier versions of MS Windows clients. Probably the more salient reason to not mix profiles is
314 that when logging off an earlier version of MS Windows, the older format of profile contents may overwrite
315 information that belongs to the newer version, resulting in loss of profile information content when that
316 user logs on again with the newer version of MS Windows.
317 </p><p>
318 If you then want to share the same Start Menu and Desktop with Windows 9x/Me, you must specify a common
319 location for the profiles. The <code class="filename">smb.conf</code> parameters that need to be common are
320 <a class="indexterm" name="id419861"></a>logon path and <a class="indexterm" name="id419868"></a>logon home.

328 There is nothing to stop you from specifying any path that you like for the location of users' profiles.
329 Therefore, you could specify that the profile be stored on a Samba server or any other SMB server,
330 as long as that SMB server supports encrypted passwords.

355 </p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id420179"></a>Get SID</h4></div></div></div><p>
358 You can identify the SID by using <code class="literal">GetSID.exe</code> from the Windows NT Server 4.0 Resource Kit.
359 </p><p>
360 Windows NT 4.0 stores the local profile information in the registry under the following key:
361 <code class="filename">HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList</code>
362 </p><p>
363 Under the ProfileList key, there will be subkeys named with the SIDs of the users who have logged
364 on to this computer. (To find the profile information for the user whose locally cached profile you want
365 to move, find the SID for the user with the <code class="literal">GetSID.exe</code> utility.) Inside the appropriate user's subkey,

369 A mandatory profile is a profile that the user does not have the ability to overwrite. During the
370 user's session, it may be possible to change the desktop environment; however, as the user logs out, all changes
371 made will be lost. If it is desired to not allow the user any ability to change the desktop environment,
372 then this must be done through policy settings. See <a href="PolicyMgmt.html" title="Chapter 26. System and Account Policies">System and Account
373 Policies</a>.
374 </p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
378 Under NO circumstances should the profile directory (or its contents) be made read-only because this may
379 render the profile unusable. Where it is essential to make a profile read-only within the UNIX file system,
380 this can be done, but then you absolutely must use the <code class="literal">fake-permissions</code> VFS module to
381 instruct MS Windows NT/200x/XP clients that the Profile has write permission for the user. See <a href="VFS.html#fakeperms" title="fake_perms">fake_perms VFS module</a>.
382 </p></div><p>
385 For MS Windows NT4/200x/XP, the procedure shown in <a href="ProfileMgmt.html#profilemigrn" title="Windows NT4 Profile Management Tools">Profile Migration from Windows
386 NT4/200x Server to Samba</a> can also be used to create mandatory profiles. To convert a group profile into
387 a mandatory profile, simply locate the <code class="filename">NTUser.DAT</code> file in the copied profile and rename
389 </p><p>
391 For MS Windows 9x/Me, it is the <code class="filename">User.DAT</code> file that must be renamed to

398 Most organizations are arranged into departments. There is a nice benefit in this fact, since usually
399 most users in a department require the same desktop applications and the same desktop layout. MS
400 Windows NT4/200x/XP will allow the use of group profiles. A group profile is a profile that is created
401 first using a template (example) user. Then using the profile migration tool (see above), the profile is
402 assigned access rights for the user group that needs to be given access to the group profile.
403 </p><p>
405 The next step is rather important. Instead of assigning a group profile to users (Using User Manager)
406 on a “<span class="quote">per-user</span>” basis, the group itself is assigned the now modified profile.
407 </p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
408 Be careful with group profiles. If the user who is a member of a group also has a personal
409 profile, then the result will be a fusion (merge) of the two.

414 does not already exist. Armed with a knowledge of where the default profile is located on the Windows
415 workstation, and knowing which registry keys affect the path from which the default profile is created,
416 it is possible to modify the default profile to one that has been optimized for the site. This has
417 significant administrative advantages.

421 To enable default per-use profiles in Windows 9x/Me, you can either use the <span class="application">Windows
423 </p><p>
424 To enable default per-user profiles in Windows 9x/Me, launch the <span class="application">System Policy
425 Editor</span>, then select <span class="guimenu">File</span> -> <span class="guimenuitem">Open Registry</span>.
426 Next click on the <span class="guiicon">Local Computer</span> icon, click on <span class="guilabel">Windows 98 System</span>,
427 select <span class="guilabel">User Profiles</span>, and click on the enable box. Remember to save the registry
428 changes.
429 </p><p>
432 (<code class="literal">regedit.exe</code>) and select the hive <code class="filename">HKEY_LOCAL_MACHINE\Network\Logon</code>.
433 Now add a DWORD type key with the name “<span class="quote">User Profiles.</span>” To enable user profiles to set the value
435 </p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id420562"></a>User Profile Handling with Windows 9x/Me</h4></div></div></div><p>
436 When a user logs on to a Windows 9x/Me machine, the local profile path,
437 <code class="filename">HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\ProfileList</code>, is checked
438 for an existing entry for that user.
439 </p><p>
440 If the user has an entry in this registry location, Windows 9x/Me checks for a locally cached
441 version of the user profile. Windows 9x/Me also checks the user's home directory (or other specified
442 directory if the location has been modified) on the server for the user profile. If a profile exists
443 in both locations, the newer of the two is used. If the user profile exists on the server but does not
444 exist on the local machine, the profile on the server is downloaded and used. If the user profile only
445 exists on the local machine, that copy is used.
446 </p><p>
447 If a user profile is not found in either location, the default user profile from the Windows
448 9x/Me machine is used and copied to a newly created folder for the logged on user. At log off, any
449 changes that the user made are written to the user's local profile. If the user has a roaming profile,
450 the changes are written to the user's profile on the server.

452 On MS Windows NT4, the default user profile is obtained from the location
453 <code class="filename">%SystemRoot%\Profiles</code>, which in a default installation will translate to
454 <code class="filename">C:\Windows NT\Profiles</code>. Under this directory on a clean install, there will be three
457 User</code>.
458 </p><p>
459 The <code class="filename">All Users</code> directory contains menu settings that are common across all
460 system users. The <code class="filename">Default User</code> directory contains menu entries that are customizable
461 per user depending on the profile settings chosen/created.
462 </p><p>
463 When a new user first logs onto an MS Windows NT4 machine, a new profile is created from:
464 </p><div class="itemizedlist"><ul type="disc"><li><p>All Users settings.</p></li><li><p>Default User settings (contains the default <code class="filename">NTUser.DAT</code> file).</p></li></ul></div><p>
466 When a user logs on to an MS Windows NT4 machine that is a member of a Microsoft security domain,
467 the following steps are followed for profile handling:
468 </p><div class="procedure"><ol type="1"><li><p> The user's account information that is obtained during the logon process
469 contains the location of the user's desktop profile. The profile path may be local to
470 the machine or it may be located on a network share. If there exists a profile at the
471 location of the path from the user account, then this profile is copied to the location
472 <code class="filename">%SystemRoot%\Profiles\%USERNAME%</code>. This profile then inherits the settings
473 in the <code class="filename">All Users</code> profile in the <code class="filename">%SystemRoot%\Profiles</code>
474 location. </p></li><li><p> If the user account has a profile path, but at its location a profile does not
475 exist, then a new profile is created in the <code class="filename">%SystemRoot%\Profiles\%USERNAME%</code>
482 If the NETLOGON share on the authenticating server (logon server) contains
483 a policy file (<code class="filename">NTConfig.POL</code>), then its contents are applied to the
484 <code class="filename">NTUser.DAT</code>, which is applied to the <code class="filename">HKEY_CURRENT_USER</code>
485 part of the registry.
486 </p></li><li><p> When the user logs out, if the profile is set to be a roaming profile, it will be
487 written out to the location of the profile. The <code class="filename">NTuser.DAT</code> file is then
488 re-created from the contents of the <code class="filename">HKEY_CURRENT_USER</code> contents. Thus,
489 should there not exist in the NETLOGON share an <code class="filename">NTConfig.POL</code> at the next
490 logon, the effect of the previous <code class="filename">NTConfig.POL</code> will still be held in the
491 profile. The effect of this is known as tattooing.
492 </p></li></ol></div><p>
493 MS Windows NT4 profiles may be <span class="emphasis"><em>local</em></span> or <span class="emphasis"><em>roaming</em></span>. A local
494 profile is stored in the <code class="filename">%SystemRoot%\Profiles\%USERNAME%</code> location. A roaming
495 profile will also remain stored in the same way, unless the following registry key is created:
497 HKEY_LOCAL_MACHINE\SYSTEM\Software\Microsoft\Windows NT\CurrentVersion\
499 </pre><p>
500 In this case, the local copy (in <code class="filename">%SystemRoot%\Profiles\%USERNAME%</code>) will be deleted
501 on logout.
502 </p><p>
504 Under MS Windows NT4, default locations for common resources like <code class="filename">My Documents</code>
505 may be redirected to a network share by modifying the following registry keys. These changes may be
506 made via use of the System Policy Editor. To do so may require that you create your own template
507 extension for the Policy Editor to allow this to be done through the GUI. Another way to do this is by
508 first creating a default user profile, then while logged in as that user, running <code class="literal">regedt32</code> to edit
509 the key settings.

537 MS Windows XP Home Edition does use default per-user profiles, but cannot participate
538 in domain security, cannot log onto an NT/ADS-style domain, and thus can obtain the profile only
539 from itself. While there are benefits in doing this, the beauty of those MS Windows clients that
540 can participate in domain logon processes is that they allow the administrator to create a global default
541 profile and enforce it through the use of Group Policy Objects (GPOs).
542 </p></div><p>
544 When a new user first logs onto an MS Windows 200x/XP machine, the default profile is obtained from
545 <code class="filename">C:\Documents and Settings\Default User</code>. The administrator can modify or change the
546 contents of this location, and MS Windows 200x/XP will gladly use it. This is far from the optimum arrangement,
547 since it will involve copying a new default profile to every MS Windows 200x/XP client workstation.
548 </p><p>
550 When MS Windows 200x/XP participates in a domain security context, and if the default user profile is not
551 found, then the client will search for a default profile in the NETLOGON share of the authenticating server.
552 In MS Windows parlance, it is <code class="filename">%LOGONSERVER%\NETLOGON\Default User,</code>
553 and if one exists there, it will copy this to the workstation in the <code class="filename">C:\Documents and
554 Settings\</code> under the Windows login name of the use.

575 the Outlook PST file over the network for every login and logout. </p><p>
576 To set this to a network location, you could use the following examples:
578 %LOGONSERVER%\%USERNAME%\Default Folders
579 </pre><p>
580 This stores the folders in the user's home directory under a directory called <code class="filename">Default
581 Folders</code>. You could also use:
583 \\<em class="replaceable"><code>SambaServer</code></em>\<em class="replaceable"><code>FolderShare</code></em>\%USERNAME%
584 </pre><p>
585 </p><p>
586 in which case the default folders are stored in the server named <em class="replaceable"><code>SambaServer</code></em>
587 in the share called <em class="replaceable"><code>FolderShare</code></em> under a directory that has the name of the
588 MS Windows user as seen by the Linux/UNIX file system. </p><p> Please note that once you have created a default profile share, you <span class="emphasis"><em>must</em></span> migrate a user's profile
589 (default or custom) to it. </p><p> MS Windows 200x/XP profiles may be <span class="emphasis"><em>local</em></span> or <span class="emphasis"><em>roaming</em></span>.
590 A roaming profile is cached locally unless the following registry key is created:
593 </p><p> </p><pre class="programlisting"> HKEY_LOCAL_MACHINE\SYSTEM\Software\Microsoft\Windows NT\CurrentVersion\
595 In this case, the local cache copy is deleted on logout.

597 The following are some typical errors, problems, and questions that have been asked on the Samba mailing lists.

599 With Samba-2.2.x, the choice you have is to enable or disable roaming profiles support. It is a
600 global-only setting. The default is to have roaming profiles, and the default path will locate them in
601 the user's home directory.
602 </p><p>
603 If disabled globally, then no one will have roaming profile ability. If enabled and you want it
604 to apply only to certain machines, then on those machines on which roaming profile support is not wanted,
605 it is necessary to disable roaming profile handling in the registry of each such machine.
606 </p><p>
607 With Samba-3, you can have a global profile setting in <code class="filename">smb.conf</code>, and you can override this by
608 per-user settings using the Domain User Manager (as with MS Windows NT4/200x). </p><p> In any case, you can configure only one profile per user. That profile can be either: </p><div class="itemizedlist"><ul type="disc"><li><p>A profile unique to that user.</p></li><li><p>A mandatory profile (one the user cannot change).</p></li><li><p>A group profile (really should be mandatory that is, unchangable).</p></li></ul></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id421646"></a>Cannot Use Roaming Profiles</h3></div></div></div><p> A user requested the following: “<span class="quote"> I do not want roaming profiles to be implemented. I want
609 to give users a local profile alone. I am totally lost with this error. For the past
610 two days I tried everything, I googled around but found no useful pointers. Please help me. </span>”</p><p> The choices are: </p><div class="variablelist"><dl><dt><span class="term">Local profiles</span></dt><dd><p> I know of no registry keys that will allow

612 stored profile is copied to the workstation to form a local profile. This local profile
613 will persist (remain on the workstation disk) unless a registry key is changed that will

615 a profile share on a central (or conveniently located local) server. </p><p> Workstations cache (store) a local copy of the profile. This cached

617 server.</p></dd><dt><span class="term">Mandatory profiles</span></dt><dd><p> Mandatory profiles can be created for
618 a user as well as for any group that a user is a member of. Mandatory profiles cannot be
619 changed by ordinary users. Only the administrator can change or reconfigure a mandatory
620 profile. </p></dd></dl></div><p> A Windows NT4/200x/XP profile can vary in size from 130KB to very large. Outlook PST files are
621 most often part of the profile and can be many gigabytes in size. On average (in a well controlled environment),
622 roaming profile size of 2MB is a good rule of thumb to use for planning purposes. In an undisciplined
623 environment, I have seen up to 2GB profiles. Users tend to complain when it takes an hour to log onto a
624 workstation, but they harvest the fruits of folly (and ignorance). </p><p> The point of this discussion is to show that roaming profiles and good controls of how they can be
625 changed as well as good discipline make for a problem-free site. </p><p> Microsoft's answer to the PST problem is to store all email in an MS Exchange Server backend. This
626 removes the need for a PST file. </p><p>Local profiles mean: </p><div class="itemizedlist"><ul type="disc"><li><p>If each machine is used by many users, then much local disk storage is needed
627 for local profiles.</p></li><li><p>Every workstation the user logs into has
628 its own profile; these can be very different from machine to machine.</p></li></ul></div><p> On the other hand, use of roaming profiles means: </p><div class="itemizedlist"><ul type="disc"><li><p>The network administrator can control the desktop environment of all users.</p></li><li><p>Use of mandatory profiles drastically reduces network management overheads.</p></li><li><p>In the long run, users will experience fewer problems.</p></li></ul></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id421795"></a>Changing the Default Profile</h3></div></div></div><p>“<span class="quote">When the client logs onto the domain controller, it searches
