- Samba can check these passwords by crypting them and comparing them
- to the hash stored in the unix user database.
- </p><p>
- Newer windows clients send encrypted passwords (so-called
- Lanman and NT hashes) over
- the wire, instead of plain text passwords. The newest clients
- will only send encrypted passwords and refuse to send plain text
- passwords, unless their registry is tweaked.
- </p><p>These passwords can't be converted to unix style encrypted
- passwords. Because of that you can't use the standard unix
- user database, and you have to store the Lanman and NT hashes
- somewhere else. </p><p>Next to a differently encrypted passwords,
- windows also stores certain data for each user
- that is not stored in a unix user database, e.g.
- workstations the user may logon from, the location where his/her
- profile is stored, etc.
- Samba retrieves and stores this information using a &quot;passdb backend&quot;.
- Commonly
- available backends are LDAP, plain text file, MySQL and nisplus.

- on the surface. This similarity is, however, only skin deep. The unix
- scheme typically sends clear text passwords over the network when
- logging in. This is bad. The SMB encryption scheme never sends the
- cleartext password over the network but it does store the 16 byte
- hashed values on disk. This is also bad. Why? Because the 16 byte hashed
- values are a &quot;password equivalent&quot;. You cannot derive the user's
- password from them, but they could potentially be used in a modified
- client to gain access to a server. This would require considerable
- technical knowledge on behalf of the attacker but is perfectly possible.
- You should thus treat the data stored in whatever
- passdb backend you use (smbpasswd file, ldap, mysql) as though it contained the
- cleartext passwords of all your users. Its contents must be kept
- secret, and the file should be protected accordingly.</p><p>Ideally we would like a password scheme which neither requires
- plain text passwords on the net or on disk. Unfortunately this
- is not available as Samba is stuck with being compatible with
- other SMB systems (WinNT, WfWg, Win95 etc). </p><div class="warning" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Warning</h3><p>Note that Windows NT 4.0 Service pack 3 changed the

-information such as username, LM/NT password hashes, password change times, and account

-disadvantages to this approach for sites with very large numbers of users (counted
-in the thousands).
-</p><div class="itemizedlist"><ul type="disc"><li><p>
-The first is that all lookups must be performed sequentially. Given that
-there are approximately two lookups per domain logon (one for a normal
-session connection such as when mapping a network drive or printer), this
-is a performance bottleneck for large sites. What is needed is an indexed approach
-such as is used in databases.
-</p></li><li><p>
-The second problem is that administrators who desired to replicate a
-smbpasswd file to more than one Samba server were left to use external
-tools such as <b>rsync(1)</b> and <b>ssh(1)</b>
-and wrote custom, in-house scripts.
-</p></li><li><p>
-And finally, the amount of information which is stored in an
-smbpasswd entry leaves no room for additional attributes such as
-a home directory, password expiration time, or even a Relative
-Identified (RID).
-</p></li></ul></div><p>
-As a result of these defeciencies, a more robust means of storing user attributes
-used by smbd was developed. The API which defines access to user accounts
-is commonly referred to as the samdb interface (previously this was called the passdb
-API, and is still so named in the CVS trees).

+Samba-3 implements a new capability to work concurrently with mulitple account backends.
+The possible new combinations of password backends allows Samba-3 a degree of flexibility
+and scalability that previously could be achieved only with MS Windows Active Directory.

-In order to store all user account information (UNIX and Samba) in the directory,
-it is necessary to use the sambaAccount and posixAccount objectclasses in
-combination. However, smbd will still obtain the user's UNIX account
-information via the standard C library calls (e.g. getpwnam(), et. al.).
-This means that the Samba server must also have the LDAP NSS library installed
-and functioning correctly. This division of information makes it possible to
-store all Samba account information in LDAP, but still maintain UNIX account
-information in NIS while the network is transitioning to a full LDAP infrastructure.

+In the course of development of Samba-3 a number of requests were received to provide the
+ability to migrate MS Windows NT4 SAM accounts to Samba-3 without the need to provide
+matching Unix/Linux accounts. We called this the <span class="emphasis"><em>Non Unix Accounts (NUA)</em></span>
+capability. The intent was that an administrator could decide to use the <span class="emphasis"><em>tdbsam</em></span>
+backend and by simply specifying <span class="emphasis"><em>&quot;passdb backend = tdbsam_nua, guest&quot;</em></span>
+this would allow Samba-3 to implement a solution that did not use Unix accounts per se. Late
+in the development cycle the team doing this work hit upon some obstacles that prevents this
+solution from being used. Given the delays with Samba-3 release a decision was made to NOT
+deliver this functionality until a better method of recognising NT Group SIDs from NT User
+SIDs could be found. This feature may thus return during the life cycle for the Samba-3 series.

+ This option uses nothing but the Unix/Linux <tt class="filename">/etc/passwd</tt>

+ Samba-2.2.x, and the protocol limitations imposed by MS Windows clients
+ apply likewise.
+ </p></dd><dt><span class="term">smbpasswd:</span></dt><dd><p>
+ This option allows continues use of the <tt class="filename">smbpasswd</tt>
+ file that maintains a plain ASCII (text) layout that includes the MS Windows

+ </p><p>
+ This backend should be used only for backwards compatibility with older

+ no reason to force migration at this time. Note that this tool will eventually
+ be deprecated.
+ </p></dd></dl></div><p>
+Samba-3 introduces the following new password backend capabilities:
+</p><div class="variablelist"><p class="title"><b>New Backends</b></p><dl><dt><span class="term">guest:</span></dt><dd><p>
+ This is <span class="emphasis"><em>always</em></span> required as the last backend specified.

+ </p></dd><dt><span class="term">tdbsam:</span></dt><dd><p>
+ This backend provides a rich database backend for local servers. This
+ backend is NOT suitable for multiple domain controller (ie: PDC + one
+ or more BDC) installations.
+ </p><p>
+ The <span class="emphasis"><em>tdbsam</em></span> password backend stores the old <span class="emphasis"><em>
+ smbpasswd</em></span> information PLUS the extended MS Windows NT / 200x
+ SAM information into a binary format TDB (trivial database) file.
+ The inclusion of the extended information makes it possible for Samba-3
+ to implement the same account and system access controls that are possible
+ with MS Windows NT4 and MS Windows 200x based systems.
+ </p><p>
+ The inclusion of the <span class="emphasis"><em>tdbsam</em></span> capability is a direct
+ response to user requests to allow simple site operation without the overhead
+ of the complexities of running OpenLDAP. It is recommended to use this only
+ for sites that have fewer than 250 users. For larger sites or implementations
+ the use of OpenLDAP or of Active Directory integration is strongly recommended.
+ </p></dd><dt><span class="term">ldapsam:</span></dt><dd><p>

+ </p><p>
+ Samba-3 has a new and extended LDAP implementation that requires configuration
+ of OpenLDAP with a new format samba schema. The new format schema file is
+ included in the <tt class="filename">~samba/examples/LDAP</tt> directory.
+ </p><p>
+ The new LDAP implementation significantly expands the control abilities that
+ were possible with prior versions of Samba. It is now possible to specify
+ &quot;per user&quot; profile settings, home directories, account access controls, and
+ much more. Corporate sites will see that the Samba-Team has listened to their
+ requests both for capability and to allow greater scalability.
+ </p></dd><dt><span class="term">mysqlsam (MySQL based backend):</span></dt><dd><p>
+ It is expected that the MySQL based SAM will be very popular in some corners.

+ Old windows clients send plain text passwords over the wire. Samba can check these
+ passwords by crypting them and comparing them to the hash stored in the unix user database.
+ </p><p>
+ Newer windows clients send encrypted passwords (so-called Lanman and NT hashes) over
+ the wire, instead of plain text passwords. The newest clients will send only encrypted
+ passwords and refuse to send plain text passwords, unless their registry is tweaked.
+ </p><p>
+ These passwords can't be converted to unix style encrypted passwords. Because of that
+ you can't use the standard unix user database, and you have to store the Lanman and NT
+ hashes somewhere else.
+ </p><p>
+ In addition to differently encrypted passwords, windows also stores certain data for each
+ user that is not stored in a unix user database. e.g: workstations the user may logon from,
+ the location where the users' profile is stored, and so on. Samba retrieves and stores this
+ information using a <i class="parameter"><tt>passdb backend</tt></i>. Commonly available backends are LDAP, plain text
+ file, MySQL and nisplus. For more information, see the man page for <tt class="filename">smb.conf</tt> regarding the
+ <i class="parameter"><tt>passdb backend</tt></i> parameter.

+ The unix and SMB password encryption techniques seem similar on the surface. This
+ similarity is, however, only skin deep. The unix scheme typically sends clear text
+ passwords over the network when logging in. This is bad. The SMB encryption scheme
+ never sends the cleartext password over the network but it does store the 16 byte
+ hashed values on disk. This is also bad. Why? Because the 16 byte hashed values
+ are a &quot;password equivalent&quot;. You cannot derive the user's password from them, but
+ they could potentially be used in a modified client to gain access to a server.
+ This would require considerable technical knowledge on behalf of the attacker but
+ is perfectly possible. You should thus treat the data stored in whatever passdb
+ backend you use (smbpasswd file, ldap, mysql) as though it contained the cleartext
+ passwords of all your users. Its contents must be kept secret, and the file should
+ be protected accordingly.
+ </p><p>
+ Ideally we would like a password scheme that involves neither plain text passwords
+ on the net nor on disk. Unfortunately this is not available as Samba is stuck with
+ having to be compatible with other SMB systems (WinNT, WfWg, Win95 etc).
+ </p><p>
+ Windows NT 4.0 Service pack 3 changed the default setting so that plaintext passwords
+ are disabled from being sent over the wire. This mandates either the use of encrypted
+ password support or edit the Windows NT registry to re-enable plaintext passwords.
+ </p><p>
+ The following versions of MS Windows do not support full domain security protocols,
+ although they may log onto a domain environment:
+ </p><table class="simplelist" border="0" summary="Simple list"><tr><td>MS DOS Network client 3.0 with the basic network redirector installed</td></tr><tr><td>Windows 95 with the network redirector update installed</td></tr><tr><td>Windows 98 [se]</td></tr><tr><td>Windows Me</td></tr></table><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>

+ All current release of Microsoft SMB/CIFS clients support authentication via the
+ SMB Challenge/Response mechanism described here. Enabling clear text authentication
+ does not disable the ability of the client to participate in encrypted authentication.
+ Instead, it allows the client to negotiate either plain text _or_ encrypted password
+ handling.
+ </p><p>
+ MS Windows clients will cache the encrypted password alone. Where plain text passwords
+ are re-enabled, through the appropriate registry change, the plain text password is NEVER
+ cached. This means that in the event that a network connections should become disconnected
+ (broken) only the cached (encrypted) password will be sent to the resource server to
+ affect a auto-reconnect. If the resource server does not support encrypted passwords the

+ </p><p>

+ The second way to affect Windows SID to Unix UID mapping is via the

+ Traditionally, when configuring <a href="smb.conf.5.html#ENCRYPTPASSWORDS" target="_top">&quot;encrypt
+ passwords = yes&quot;</a> in Samba's <tt class="filename">smb.conf</tt> file, user account
+ information such as username, LM/NT password hashes, password change times, and account
+ flags have been stored in the <tt class="filename">smbpasswd(5)</tt> file. There are several
+ disadvantages to this approach for sites with very large numbers of users (counted
+ in the thousands).
+ </p><div class="itemizedlist"><ul type="disc"><li><p>
+ The first is that all lookups must be performed sequentially. Given that
+ there are approximately two lookups per domain logon (one for a normal
+ session connection such as when mapping a network drive or printer), this
+ is a performance bottleneck for large sites. What is needed is an indexed approach
+ such as is used in databases.
+ </p></li><li><p>
+ The second problem is that administrators who desire to replicate a smbpasswd file
+ to more than one Samba server were left to use external tools such as
+ <b class="command">rsync(1)</b> and <b class="command">ssh(1)</b> and wrote custom,
+ in-house scripts.
+ </p></li><li><p>
+ And finally, the amount of information which is stored in an smbpasswd entry leaves
+ no room for additional attributes such as a home directory, password expiration time,
+ or even a Relative Identifier (RID).
+ </p></li></ul></div><p>
+ As a result of these deficiencies, a more robust means of storing user attributes
+ used by smbd was developed. The API which defines access to user accounts
+ is commonly referred to as the samdb interface (previously this was called the passdb
+ API, and is still so named in the Samba CVS trees).
+ </p><p>
+ Samba-3 provides an enhanced set of passdb backends that overcome the deficiencies
+ of the smbpasswd plain text database. These are tdbsam, ldapsam, and xmlsam.
+ Of these ldapsam will be of most interest to large corporate or enterprise sites.

+ </p><p>
+ As a general guide the Samba-Team do NOT recommend using the tdbsam backend for sites
+ that have 250 or more users. Additionally, tdbsam is not capable of scaling for use
+ in sites that require PDB/BDC implmentations that requires replication of the account
+ database. Clearly, for reason of scalability the use of ldapsam should be encouraged.

+ </p><p>
+ Just as the smbpasswd file is meant to store information which supplements a
+ user's <tt class="filename">/etc/passwd</tt> entry, so is the sambaAccount object
+ meant to supplement the UNIX user account information. A sambaAccount is a
+ <tt class="constant">STRUCTURAL</tt> objectclass so it can be stored individually
+ in the directory. However, there are several fields (e.g. uid) which overlap
+ with the posixAccount objectclass outlined in RFC2307. This is by design.
+ </p><p>
+ In order to store all user account information (UNIX and Samba) in the directory,
+ it is necessary to use the sambaAccount and posixAccount objectclasses in
+ combination. However, smbd will still obtain the user's UNIX account
+ information via the standard C library calls (e.g. getpwnam(), et. al.).
+ This means that the Samba server must also have the LDAP NSS library installed
+ and functioning correctly. This division of information makes it possible to
+ store all Samba account information in LDAP, but still maintain UNIX account
+ information in NIS while the network is transitioning to a full LDAP infrastructure.

This note was attached to the Samba 2.2.8 release notes as it contained an
important security fix. The information contained here applies to Samba
installations in general.
-</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2900517"></a>Using host based protection</h2></div></div><p>
-In many installations of Samba the greatest threat comes for outside
-your immediate network. By default Samba will accept connections from
-any host, which means that if you run an insecure version of Samba on
-a host that is directly connected to the Internet you can be
-especially vulnerable.
</p><p>
-One of the simplest fixes in this case is to use the <b>hosts allow</b> and
-<b>hosts deny</b> options in the Samba <tt>smb.conf</tt> configuration file to only
-allow access to your server from a specific range of hosts. An example
-might be:
-</p><pre class="programlisting">
- hosts allow = 127.0.0.1 192.168.2.0/24 192.168.3.0/24
- hosts deny = 0.0.0.0/0
-</pre><p>
-The above will only allow SMB connections from 'localhost' (your own
-computer) and from the two private networks 192.168.2 and
-192.168.3. All other connections will be refused as soon
-as the client sends its first packet. The refusal will be marked as a
-'not listening on called name' error.
-</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2900967"></a>Using interface protection</h2></div></div><p>
-By default Samba will accept connections on any network interface that
-it finds on your system. That means if you have a ISDN line or a PPP
-connection to the Internet then Samba will accept connections on those
-links. This may not be what you want.
-</p><p>
-You can change this behaviour using options like the following:
-</p><pre class="programlisting">
- interfaces = eth* lo
- bind interfaces only = yes
-</pre><p>
-This tells Samba to only listen for connections on interfaces with a
-name starting with 'eth' such as eth0, eth1, plus on the loopback
-interface called 'lo'. The name you will need to use depends on what
-OS you are using, in the above I used the common name for Ethernet
-adapters on Linux.
-</p><p>
-If you use the above and someone tries to make a SMB connection to
-your host over a PPP interface called 'ppp0' then they will get a TCP
-connection refused reply. In that case no Samba code is run at all as
-the operating system has been told not to pass connections from that
-interface to any samba process.
-</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2901018"></a>Using a firewall</h2></div></div><p>
-Many people use a firewall to deny access to services that they don't
-want exposed outside their network. This can be a very good idea,
-although I would recommend using it in conjunction with the above
-methods so that you are protected even if your firewall is not active
-for some reason.
+A new apprentice reported for duty to the Chief Engineer of a boiler house. He said, &quot;Here I am,
+if you will show me the boiler I'll start working on it.&quot; Then engineer replied, &quot;You're leaning
+on it!&quot;
</p><p>
-If you are setting up a firewall then you need to know what TCP and
-UDP ports to allow and block. Samba uses the following:
-</p><pre class="programlisting">
- UDP/137 - used by nmbd
- UDP/138 - used by nmbd
- TCP/139 - used by smbd
- TCP/445 - used by smbd
-</pre><p>
-The last one is important as many older firewall setups may not be
-aware of it, given that this port was only added to the protocol in
-recent years.
-</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2901061"></a>Using a IPC$ share deny</h2></div></div><p>
-If the above methods are not suitable, then you could also place a
-more specific deny on the IPC$ share that is used in the recently
-discovered security hole. This allows you to offer access to other
-shares while denying access to IPC$ from potentially untrustworthy
-hosts.
+Security concerns are just like that: You need to know a little about the subject to appreciate
+how obvious most of it really is. The challenge for most of us is to discover that first morsel
+of knowledge with which we may unlock the secrets of the masters.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2929550"></a>Features and Benefits</h2></div></div><div></div></div><p>
+There are three level at which security principals must be observed in order to render a site
+at least moderately secure. These are: the perimeter firewall, the configuration of the host
+server that is running Samba, and Samba itself.
</p><p>
-To do that you could use:
-</p><pre class="programlisting">
- [ipc$]
- hosts allow = 192.168.115.0/24 127.0.0.1
- hosts deny = 0.0.0.0/0
-</pre><p>
-this would tell Samba that IPC$ connections are not allowed from
-anywhere but the two listed places (localhost and a local
-subnet). Connections to other shares would still be allowed. As the
-IPC$ share is the only share that is always accessible anonymously
-this provides some level of protection against attackers that do not
-know a username/password for your host.
+Samba permits a most flexible approach to network security. As far as possible Samba implements
+the latest protocols to permit more secure MS Windows file and print operations.
</p><p>

+The key challenge of security is the fact that protective measures suffice at best
+only to close the door on known exploits and breach techniques. Never assume that
+because you have followed these few measures that the Samba server is now an impenetrable
+fortress! Given the history of information systems so far, it is only a matter of time
+before someone will find yet another vulnerability.
+</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2928229"></a>Using host based protection</h3></div></div><div></div></div><p>
+ In many installations of Samba the greatest threat comes for outside
+ your immediate network. By default Samba will accept connections from
+ any host, which means that if you run an insecure version of Samba on
+ a host that is directly connected to the Internet you can be
+ especially vulnerable.
+ </p><p>
+ One of the simplest fixes in this case is to use the <i class="parameter"><tt>hosts allow</tt></i> and
+ <i class="parameter"><tt>hosts deny</tt></i> options in the Samba <tt class="filename">smb.conf</tt> configuration file to only
+ allow access to your server from a specific range of hosts. An example
+ might be:
+ </p><pre class="programlisting">
+ hosts allow = 127.0.0.1 192.168.2.0/24 192.168.3.0/24
+ hosts deny = 0.0.0.0/0
+ </pre><p>
+ The above will only allow SMB connections from 'localhost' (your own
+ computer) and from the two private networks 192.168.2 and
+ 192.168.3. All other connections will be refused as soon
+ as the client sends its first packet. The refusal will be marked as a
+ <span class="errorname">not listening on called name</span> error.
+ </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2928297"></a>User based protection</h3></div></div><div></div></div><p>
+ If you want to restrict access to your server to valid users only then the following
+ method may be of use. In the <tt class="filename">smb.conf</tt> <i class="parameter"><tt>[globals]</tt></i> section put:
+ </p><pre class="programlisting">
+ valid users = @smbusers, jacko
+ </pre><p>
+ What this does is, it restricts all server access to either the user <span class="emphasis"><em>jacko</em></span>
+ or to members of the system group <span class="emphasis"><em>smbusers</em></span>.
+ </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2928349"></a>Using interface protection</h3></div></div><div></div></div><p>
+ By default Samba will accept connections on any network interface that
+ it finds on your system. That means if you have a ISDN line or a PPP
+ connection to the Internet then Samba will accept connections on those
+ links. This may not be what you want.
+ </p><p>
+ You can change this behaviour using options like the following:
+ </p><pre class="programlisting">
+ interfaces = eth* lo
+ bind interfaces only = yes
+ </pre><p>
+ This tells Samba to only listen for connections on interfaces with a
+ name starting with 'eth' such as eth0, eth1, plus on the loopback
+ interface called 'lo'. The name you will need to use depends on what
+ OS you are using, in the above I used the common name for Ethernet
+ adapters on Linux.
+ </p><p>
+ If you use the above and someone tries to make a SMB connection to
+ your host over a PPP interface called 'ppp0' then they will get a TCP
+ connection refused reply. In that case no Samba code is run at all as
+ the operating system has been told not to pass connections from that
+ interface to any samba process.

+ Many people use a firewall to deny access to services that they don't
+ want exposed outside their network. This can be a very good idea,
+ although I would recommend using it in conjunction with the above
+ methods so that you are protected even if your firewall is not active
+ for some reason.
+ </p><p>
+ If you are setting up a firewall then you need to know what TCP and
+ UDP ports to allow and block. Samba uses the following:
+ </p><table class="simplelist" border="0" summary="Simple list"><tr><td>UDP/137 - used by nmbd</td></tr><tr><td>UDP/138 - used by nmbd</td></tr><tr><td>TCP/139 - used by smbd</td></tr><tr><td>TCP/445 - used by smbd</td></tr></table><p>
+ The last one is important as many older firewall setups may not be
+ aware of it, given that this port was only added to the protocol in
+ recent years.
+ </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2928455"></a>Using a IPC$ share deny</h3></div></div><div></div></div><p>
+ If the above methods are not suitable, then you could also place a
+ more specific deny on the IPC$ share that is used in the recently
+ discovered security hole. This allows you to offer access to other
+ shares while denying access to IPC$ from potentially untrustworthy
+ hosts.
+ </p><p>
+ To do that you could use:
+ </p><pre class="programlisting">
+[ipc$]
+ hosts allow = 192.168.115.0/24 127.0.0.1
+ hosts deny = 0.0.0.0/0
+ </pre><p>
+ this would tell Samba that IPC$ connections are not allowed from
+ anywhere but the two listed places (localhost and a local
+ subnet). Connections to other shares would still be allowed. As the
+ IPC$ share is the only share that is always accessible anonymously
+ this provides some level of protection against attackers that do not
+ know a username/password for your host.
+ </p><p>
+ If you use this method then clients will be given a <span class="errorname">access denied</span>
+ reply when they try to access the IPC$ share. That means that those
+ clients will not be able to browse shares, and may also be unable to
+ access some other resources.
+ </p><p>
+ This is not recommended unless you cannot use one of the other
+ methods listed above for some reason.

+If all of samba and host platform configuration were really as intuitive as one might like then this
+section would not be necessary. Security issues are often vexing for a support person to resolve, not
+because of the complexity of the problem, but for reason that most admininstrators who post what turns
+out to be a security problem request are totally convinced that the problem is with Samba.
+</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2928602"></a>Smbclient works on localhost, but the network is dead</h3></div></div><div></div></div><p>
+ This is a very common problem. Red Hat Linux (as do others) will install a default firewall.
+ With the default firewall in place only traffic on the loopback adapter (IP address 127.0.0.1)
+ will be allowed through the firewall.
+ </p><p>
+ The solution is either to remove the firewall (stop it) or to modify the firewall script to
+ allow SMB networking traffic through. See section above in this chapter.
+ </p></div><div xmlns:ns42="" class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2928626"></a>Why can users access home directories of other users?</h3></div></div><div></div></div><p>
+ &#8220;<span class="quote">
+ We are unable to keep individual users from mapping to any other user's
+ home directory once they have supplied a valid password! They only need
+ to enter their own password. I have not found *any* method that I can

+ </span>&#8221;</p><p>
+ This is not a security flaw, it is by design. Samba allows
+ users to have *exactly* the same access to the UNIX filesystem
+ as they would if they were logged onto the UNIX box, except
+ that it only allows such views onto the file system as are
+ allowed by the defined shares.
+ </p><p>
+ This means that if your UNIX home directories are set up
+ such that one user can happily cd into another users
+ directory and do an ls, the UNIX security solution is to
+ change the UNIX file permissions on the users home directories
+ such that the cd and ls would be denied.
+ </p><p>
+ Samba tries very hard not to second guess the UNIX administrators
+ security policies, and trusts the UNIX admin to set
+ the policies and permissions he or she desires.
+ </p><p>
