client write and read operations on a Samba server and sends this data
over a socket to a helper program, which feeds a SQL database. More
information on the helper programs can be obtained from the
homepage of the project at:

anonymization of user related data.</p></dd></dl></div></div><div class="refsect1" title="EXAMPLES"><a name="id2489634"></a><h2>EXAMPLES</h2><p>The module running on share "example_share", using a unix domain socket</p><pre class="programlisting">
