This <code>mod_quotatab</code> submodule is contained in the
<code>mod_quotatab_ldap.c</code>, and is found in the <code>contrib/</code>
area of the ProFTPD source distribution.  See the <code>mod_quotatab</code>
<a href="mod_quotatab.html#Installation">installation</a> instructions.

<p>
This submodule provides the LDAP-specific &quot;driver&quot; for retrieving
quota limit table information from an LDAP server.

<hr><h2><a name="LDAPTables">LDAP Limit Quota Tables</a></h2>
LDAP-based quota tables (<em>source-type</em> of &quot;ldap&quot;) can
only be used for limit tables, <b>not</b> for tally tables.  The frequent
updates needed for maintaining tally tables mean that LDAP is not well-suited
to handle tally table storage.

<p>
The <code>mod_quotatab_ldap</code> module supports the &quot;ldap&quot; string
for the <em>source-type</em> parameter of the
<a href="mod_quotatab.html#QuotaLimitTable"><code>QuotaLimitTable</code></a>
configuration directive.

<p>
To enable LDAP-provisioned limit tables, you need to configure
<code>mod_ldap</code> to lookup the proper attribute using the
<a href="http://www.proftpd.org/docs/directives/linked/config_ref_LDAPDoQuotaLookups.html"><code>LDAPDoQuotaLookups</code></a> configuration directive.

<p>
The LDAP attribute to be looked up (named <code>ftpQuota</code> by default)
should contain a comma-separated list of 8 values, in the following order:
<pre>
  <i>per_session, limit_type, bytes_in_avail, bytes_out_avail, bytes_xfer_avail,
    files_in_avail, files_out_avail, files_xfer_avail</i>
</pre>
For example:
<pre>
  &quot;false,hard,100,100,100,100,100,100&quot;
</pre>

<p>
An example <code>proftpd.conf</code> configuration might look like:
<pre>
  &lt;IfModule mod_quotatab.c&gt;
    &lt;IfModule mod_quotatab_ldap.c&gt;
      # Enable LDAP quota lookups
      LDAPDoQuotaLookups on

# Use an LDAP-based limit table.  Note that there is no additional
      # information supplied after the source-type: this is intentional. 
      # mod_ldap handles the rest.
      QuotaLimitTable ldap:
    &lt;/IfModule&gt;

# Use a file-based tally table
    QuotaTallyTable file:/usr/local/proftpd/ftpquota.tallytab
  &lt;/IfModule&gt;
</pre>
