+ <para>This tool is part of the <citerefentry><refentrytitle>samba</refentrytitle>
+ <manvolnum>7</manvolnum></citerefentry> suite.</para>
+
+ <para><command>ntlm_auth4</command> is a helper utility that authenticates
+ users using NT/LM authentication. It returns 0 if the users is authenticated
+ successfully and 1 if access was denied. ntlm_auth4 uses winbind to access
+ the user and authentication data for a domain. This utility
+ is only indended to be used by other programs (currently squid).

+ <title>OPERATIONAL REQUIREMENTS</title>
+
+ <para>
+ The <citerefentry><refentrytitle>winbindd</refentrytitle>
+ <manvolnum>8</manvolnum></citerefentry> daemon must be operational
+ for many of these commands to function.</para>
+
+ <para>Some of these commands also require access to the directory
+ <filename>winbindd_privileged</filename> in
+ <filename>$LOCKDIR</filename>. This should be done either by running
+ this command as root or providing group access
+ to the <filename>winbindd_privileged</filename> directory. For
+ security reasons, this directory should not be world-accessable. </para>

+ <title>EXAMPLE SETUP</title>
+
+ <para>To setup ntlm_auth4 for use by squid 2.5, with both basic and
+ NTLMSSP authentication, the following
+ should be placed in the <filename>squid.conf</filename> file.
+<programlisting>
+auth_param ntlm program ntlm_auth4 --helper-protocol=squid-2.5-ntlmssp
+auth_param basic program ntlm_auth4 --helper-protocol=squid-2.5-basic
+auth_param basic children 5
+auth_param basic realm Squid proxy-caching web server
+auth_param basic credentialsttl 2 hours
+</programlisting></para>
+
+<note><para>This example assumes that ntlm_auth4 has been installed into your
+ path, and that the group permissions on
+ <filename>winbindd_privileged</filename> are as described above.</para></note>
+
+ <para>To setup ntlm_auth4 for use by squid 2.5 with group limitation in addition to the above
+ example, the following should be added to the <filename>squid.conf</filename> file.
+<programlisting>
+auth_param ntlm program ntlm_auth4 --helper-protocol=squid-2.5-ntlmssp --require-membership-of='WORKGROUP\Domain Users'
+auth_param basic program ntlm_auth4 --helper-protocol=squid-2.5-basic --require-membership-of='WORKGROUP\Domain Users'
