+<para>
+Roaming profiles are feared by some, hated by a few, loved by many, and a Godsend for
+some administrators.
+</para>
+
+<para>
+Roaming profiles allow an administrator to make available a consistent user desktop
+as the user moves from one machine to another. This chapter provides much information
+regarding how to configure and manage roaming profiles.
+</para>
+
+<para>
+While roaming profiles might sound like nirvana to some, they are a real and tangible
+problem to others. In particular, users of mobile computing tools, where often there may not
+be a sustained network connection, are often better served by purely local profiles.
+This chapter provides information to help the Samba administrator deal with those
+situations.

+<title>Roaming Profiles</title>
+
+<warning>
+<para>
+Roaming profiles support is different for Windows 9x/Me and Windows NT4/200x.
+</para>
+</warning>
+
+<para>
+Before discussing how to configure roaming profiles, it is useful to see how
+Windows 9x/Me and Windows NT4/200x clients implement these features.
+</para>
+
+<para>
+Windows 9x/Me clients send a NetUserGetInfo request to the server to get the user's
+profiles location. However, the response does not have room for a separate
+profiles location field, only the user's home share. This means that Windows 9x/Me
+profiles are restricted to being stored in the user's home directory.
+</para>
+
+
+<para>
+Windows NT4/200x clients send a NetSAMLogon RPC request, which contains many fields
+including a separate field for the location of the user's profiles.
+</para>
+
+<sect2>
+<title>Samba Configuration for Profile Handling</title>
+
+<para>
+This section documents how to configure Samba for MS Windows client profile support.
+</para>
+
+<sect3>
+<title>NT4/200x User Profiles</title>
+
+<para>
+For example, to support Windows NT4/200x clients, set the followoing in the [global] section of the &smb.conf; file:
+</para>
+
+<para>
+<smbconfblock>
+<smbconfoption><name>logon path</name><value> </value></smbconfoption>
+<member><parameter>\\profileserver\profileshare\profilepath\%U\moreprofilepath</parameter></member>
+</smbconfblock>
+
+This is typically implemented like:
+
+<smbconfblock>
+<smbconfoption><name>logon path</name><value>\\%L\Profiles\%u</value></smbconfoption>
+</smbconfblock>
+where <quote>%L</quote> translates to the name of the Samba server and <quote>%u</quote> translates to the user name.
+</para>
+
+<para>
+The default for this option is <filename>\\%N\%U\profile</filename>, namely <filename>\\sambaserver\username\profile</filename>.
+The <filename>\\%N\%U</filename> service is created automatically by the [homes] service. If you are using
+a Samba server for the profiles, you must make the share that is specified in the logon path
+browseable. Please refer to the man page for &smb.conf; in respect of the different
+semantics of <quote>%L</quote> and <quote>%N</quote>, as well as <quote>%U</quote> and <quote>%u</quote>.
+</para>
+
+<note>
+<para>
+MS Windows NT/200x clients at times do not disconnect a connection to a server between logons. It is recommended
+to not use the <smbconfsection>homes</smbconfsection> meta-service name as part of the profile share path.
+</para>
+</note>
+</sect3>
+
+<sect3>
+<title>Windows 9x/Me User Profiles</title>
+
+<para>
+To support Windows 9x/Me clients, you must use the <smbconfoption><name>logon home</name></smbconfoption>
+parameter. Samba has been fixed so <userinput>net use /home</userinput> now works as well and it, too, relies
+on the <command>logon home</command> parameter.
+</para>
+
+<para>
+By using the logon home parameter, you are restricted to putting Windows 9x/Me profiles in the user's home
+directory. But wait! There is a trick you can use. If you set the following in the
+<smbconfsection>[global]</smbconfsection> section of your &smb.conf; file:
+</para>
+<para><smbconfblock>
+<smbconfoption><name>logon home</name><value>\\%L\%U\.profiles</value></smbconfoption>
+</smbconfblock></para>
+
+<para>
+then your Windows 9x/Me clients will dutifully put their clients in a subdirectory
+of your home directory called <filename>.profiles</filename> (making them hidden).
+</para>
+
+<para>
+Not only that, but <userinput>net use /home</userinput> will also work because of a feature in
+Windows 9x/Me. It removes any directory stuff off the end of the home directory area
+and only uses the server and share portion. That is, it looks like you
+specified <filename>\\%L\%U</filename> for <smbconfoption><name>logon home</name></smbconfoption>.
+</para>
+</sect3>
+
+<sect3>
+<title>Mixed Windows 9x/Me and Windows NT4/200x User Profiles</title>
+
+<para>
+You can support profiles for Windows 9x and Windows NT clients by setting both the
+<smbconfoption><name>logon home</name></smbconfoption> and <smbconfoption><name>logon path</name></smbconfoption> parameters. For example:
+</para>
+
+<para><smbconfblock>
+<smbconfoption><name>logon home</name><value>\\%L\%u\.profiles</value></smbconfoption>
+<smbconfoption><name>logon path</name><value>\\%L\profiles\%u</value></smbconfoption>

+<para>
+When a user first logs in on Windows 9X, the file user.DAT is created, as are folders
+<filename>Start Menu</filename>, <filename>Desktop</filename>, <filename>Programs</filename>, and
+<filename>Nethood</filename>. These directories and their contents will be merged with the local
+versions stored in <filename>c:\windows\profiles\username</filename> on subsequent logins, taking the
+most recent from each. You will need to use the <smbconfsection>[global]</smbconfsection> options
+<smbconfoption><name>preserve case</name><value>yes</value></smbconfoption>,
+<smbconfoption><name>short preserve case</name><value>yes</value></smbconfoption> and
+<smbconfoption><name>case sensitive</name><value>no</value></smbconfoption>
+in order to maintain capital letters in shortcuts in any of the profile folders.
+</para>
+
+<para>
+The <filename>user.DAT</filename> file contains all the user's preferences. If you wish to enforce a set of preferences,
+rename their <filename>user.DAT</filename> file to <filename>user.MAN</filename>, and deny them write access to this file.

+ </para> </listitem>
+</orderedlist>
+
+<para> Under Windows 9x/ME, profiles are downloaded from the Primary Logon. If you have the Primary Logon
+as <quote>Client for Novell Networks</quote>, then the profiles and logon script will be downloaded from
+your Novell Server. If you have the Primary Logon as <quote>Windows Logon</quote>, then the profiles will
+be loaded from the local machine &smbmdash; a bit against the concept of roaming profiles, it would seem! </para>
+
+<para>
+You will now find that the Microsoft Networks Login box contains <constant>[user, password, domain]</constant> instead
+of just <constant>[user, password]</constant>. Type in the Samba server's domain name (or any other domain known to exist,
+but bear in mind that the user will be authenticated against this domain and profiles downloaded from it,
+if that domain logon server supports it), user name and user's password.
+</para>
+
+<para> Once the user has been successfully validated, the Windows 9x/Me machine will inform you that
+<computeroutput>The user has not logged on before</computeroutput> and asks you <computeroutput>Do you
+wish to save the user's preferences?</computeroutput> Select <guibutton>Yes</guibutton>. </para>
+
+<para> Once the Windows 9x/Me client comes up with the desktop, you should be able to examine the
+contents of the directory specified in the <smbconfoption><name>logon path</name></smbconfoption> on
+the Samba server and verify that the <filename>Desktop</filename>, <filename>Start Menu</filename>,
+<filename>Programs</filename> and <filename>Nethood</filename> folders have been created. </para>
+
+<para> These folders will be cached locally on the client, and updated when the user logs off (if
+you haven't made them read-only by then). You will find that if the user creates further folders or
+shortcut, that the client will merge the profile contents downloaded with the contents of the profile
+directory already on the local client, taking the newest folders and shortcut from each set. </para>
+
+<para> If you have made the folders/files read-only on the Samba server, then you will get errors from
+the Windows 9x/Me machine on logon and logout as it attempts to merge the local and remote profile.
+Basically, if you have any errors reported by the Windows 9x/Me machine, check the UNIX file permissions
+and ownership rights on the profile directory contents, on the Samba server. </para>
+

+<title>Windows NT4 Workstation</title>
+
+<para> When a user first logs in to a Windows NT Workstation, the profile NTuser.DAT is created. The profile
+location can be now specified through the <smbconfoption><name>logon path</name></smbconfoption> parameter.
+</para>
+
+<para> There is a parameter that is now available for use with NT Profiles: <smbconfoption><name>logon drive</name></smbconfoption>.
+This should be set to <filename>H:</filename> or any other drive, and should be used in conjunction with
+the new <smbconfoption><name>logon home</name></smbconfoption> parameter. </para>
+
+<para> The entry for the NT4 profile is a directory not a file. The NT help on Profiles mentions that a
+directory is also created with a .PDS extension. The user, while logging in, must have write permission
+to create the full profile path (and the folder with the .PDS extension for those situations where it
+might be created.) </para>
+
+<para> In the profile directory, Windows NT4 creates more folders than Windows 9x/Me. It creates
+<filename>Application Data</filename> and others, as well as <filename>Desktop</filename>,
+<filename>Nethood</filename>, <filename>Start Menu,</filename> and <filename>Programs</filename>.
+The profile itself is stored in a file <filename>NTuser.DAT</filename>. Nothing appears to be stored
+in the .PDS directory, and its purpose is currently unknown. </para>
+
+<para> You can use the <application>System Control Panel</application> to copy a local profile onto
+a Samba server (see NT Help on Profiles; it is also capable of firing up the correct location in the
+<application>System Control Panel</application> for you). The NT Help file also mentions that renaming
+<filename>NTuser.DAT</filename> to <filename>NTuser.MAN</filename> turns a profile into a mandatory one.
+</para>

+ <title>Sharing Profiles between W9x/Me and NT4/200x/XP Workstations</title>
+
+<para> Sharing of desktop profiles between Windows versions is not recommended. Desktop profiles are an
+evolving phenomenon and profiles for later versions of MS Windows clients add features that may interfere
+with earlier versions of MS Windows clients. Probably the more salient reason to not mix profiles is
+that when logging off an earlier version of MS Windows, the older format of profile contents may overwrite
+information that belongs to the newer version resulting in loss of profile information content when that
+user logs on again with the newer version of MS Windows. </para>
+
+<para> If you then want to share the same Start Menu/Desktop with W9x/Me, you will need to specify a common
+location for the profiles. The &smb.conf; parameters that need to be common are

+A Mandatory Profile is a profile that the user does not have the ability to overwrite. During the

+made will be lost. If it is desired to not allow the user any ability to change the desktop environment,

+
+<note><para> Under NO circumstances should the profile directory (or its

+Where it is essential to make a profile read-only within the UNIX file
+system, this can be done but then you absolutely must use the
+<command>fake-permissions</command> VFS module to instruct MS Windows
+NT/200x/XP clients that the Profile has write permission for the user.
+See <link linkend="fakeperms">fake_perms VFS module</link>. </para></note>

+first using a template (example) user. Then using the profile migration tool (see above), the profile is
+assigned access rights for the user group that needs to be given access to the group profile. </para>

+<para> There must be a <smbconfsection>[netlogon]</smbconfsection> share that is world readable. It is
+a good idea to add a logon script to pre-set printer and drive connections. There is also a facility
+for automatically synchronizing the workstation time clock with that of the logon server (another good
+thing to do). </para>

+<para> Windows clients need to be members of the domain. Workgroup machines do not use network logons
