This directive sets the directory where you keep the Certificates of
Certification Authorities (CAs) whose clients you deal with. These are used to
verify the client certificate on Client Authentication.</p>
<p>
The files in this directory have to be PEM-encoded and are accessed through
hash filenames. So usually you can't just place the Certificate files
there: you also have to create symbolic links named
<em>hash-value</em><code>.N</code>. And you should always make sure this directory
contains the appropriate symbolic links. Use the <code>Makefile</code> which
comes with mod_ssl to accomplish this task.</p>

<p>When a client certificate is requested by mod_ssl, a list of
<em>acceptable Certificate Authority names</em> is sent to the client
in the SSL handshake.  These CA names can be used by the client to
select an appropriate client certificate out of those it has
available.</p>

<p>If neither of the directives <code class="directive"><a href="#sslcadnrequestpath">SSLCADNRequestPath</a></code> or <code class="directive"><a href="#sslcadnrequestfile">SSLCADNRequestFile</a></code> are given, then the
set of acceptable CA names sent to the client is the names of all the
CA certificates given by the <code class="directive"><a href="#sslcacertificatefile">SSLCACertificateFile</a></code> and <code class="directive"><a href="#sslcacertificatepath">SSLCACertificatePath</a></code> directives; in other
words, the names of the CAs which will actually be used to verify the
client certificate.</p>

<p>In some circumstances, it is useful to be able to send a set of
acceptable CA names which differs from the actual CAs used to verify
the client certificate - for example, if the client certificates are
signed by intermediate CAs.  In such cases, <code class="directive"><a href="#sslcadnrequestpath">SSLCADNRequestPath</a></code> and/or <code class="directive"><a href="#sslcadnrequestfile">SSLCADNRequestFile</a></code> can be used; the
acceptable CA names are then taken from the complete set of
certificates in the directory and/or file specified by this pair of
directives.</p>

<p><code class="directive"><a href="#sslcadnrequestfile">SSLCADNRequestFile</a></code> must
specify an <em>all-in-one</em> file containing a concatenation of
PEM-encoded CA certificates.</p>

<div class="example"><h3>Example</h3><p><code>
SSLCADNRequestFile /usr/local/apache2/conf/ca-names.crt
</code></p></div>

<p>This optional directive can be used to specify the set of

This directive sets the directory where you keep the Certificate Revocation
Lists (CRL) of Certification Authorities (CAs) whose clients you deal with.
These are used to revoke the client certificate on Client Authentication.</p>
<p>
The files in this directory have to be PEM-encoded and are accessed through
hash filenames. So usually you have not only to place the CRL files there.
Additionally you have to create symbolic links named
<em>hash-value</em><code>.rN</code>. And you should always make sure this directory
contains the appropriate symbolic links. Use the <code>Makefile</code> which
comes with <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> to accomplish this task.</p>

<p>
This directive sets the optional <em>all-in-one</em> file where you can
assemble the certificates of Certification Authorities (CA) which form the
certificate chain of the server certificate. This starts with the issuing CA
certificate of of the server certificate and can range up to the root CA
certificate. Such a file is simply the concatenation of the various
PEM-encoded CA Certificate files, usually in certificate chain order.</p>
<p>
This should be used alternatively and/or additionally to <code class="directive"><a href="#sslcacertificatepath">SSLCACertificatePath</a></code> for explicitly
constructing the server certificate chain which is sent to the browser
in addition to the server certificate. It is especially useful to
avoid conflicts with CA certificates when using client
authentication. Because although placing a CA certificate of the
server certificate chain into <code class="directive"><a href="#sslcacertificatepath">SSLCACertificatePath</a></code> has the same effect
for the certificate chain construction, it has the side-effect that
client certificates issued by this same CA certificate are also
accepted on client authentication.</p>
<p>
But be careful: Providing the certificate chain works only if you are using a
<em>single</em> RSA <em>or</em> DSA based server certificate. If you are
using a coupled RSA+DSA certificate pair, this will work only if actually both
certificates use the <em>same</em> certificate chain. Else the browsers will be
confused in this situation.</p>

SSLCertificateChainFile /usr/local/apache2/conf/ssl.crt/ca.crt
</code></p></div>

This directive points to the PEM-encoded Certificate file for the server and
optionally also to the corresponding RSA or DSA Private Key file for it
(contained in the same file). If the contained Private Key is encrypted the
Pass Phrase dialog is forced at startup time. This directive can be used up to
two times (referencing different filenames) when both a RSA and a DSA based
server certificate is used in parallel.</p>
