<h2><a name="usingssltls" id="usingssltls">Using SSL</a></h2>

    <p>The ability to create an SSL connections to an LDAP server 
    is defined by the directives <code class="directive"><a href="#&#10;    ldaptrustedca">
    LDAPTrustedCA</a></code> and <code class="directive"><a href="#&#10;    ldaptrustedcatype">
    LDAPTrustedCAType</a></code>. These directives specify the certificate
    file or database and the certificate type. Whenever the LDAP url
    includes <em>ldaps://</em>, <code class="module"><a href="../mod/mod_ldap.html">mod_ldap</a></code> will establish
    a secure connection to the LDAP server.</p>

    <div class="example"><p><code>
      # Establish an SSL LDAP connection. Requires that <br />
      # mod_ldap and mod_auth_ldap be loaded. Change the <br />
      # "yourdomain.example.com" to match your domain.<br />
      <br />
      LDAPTrustedCA /certs/certfile.der<br />

    <p>If <code class="module"><a href="../mod/mod_ldap.html">mod_ldap</a></code> is linked against the
    Netscape/iPlanet LDAP SDK, it will not talk to any SSL server
    unless that server has a certificate signed by a known Certificate
    Authority. As part of the configuration
    <code class="module"><a href="../mod/mod_ldap.html">mod_ldap</a></code> needs to be told where it can find
    a database containing the known CAs. This database is in the same
    format as Netscape Communicator's <code>cert7.db</code>
    database. The easiest way to get this file is to start up a fresh
    copy of Netscape, and grab the resulting
    <code>$HOME/.netscape/cert7.db</code> file.</p>
