+This referenced file is simply the concatenation of the various
+PEM-encoded certificate files. Use this directive alternatively or
+additionally to SSLProxyMachineCertificatePath
. The
+referenced file can contain any number of pairs of client certificate
+and associated private key. Each pair can be specified in either
+(certificate, key) or (key, certificate) order. If the file includes
+any non-leaf certificate, or any unmatched key and certificate pair, a
+configuration error will be issued at startup.
When challenged to provide a client certificate by a remote server,
+the server should provide a list of acceptable certificate
+authority names in the challenge. If such a list is not
+provided, mod_ssl
will use the first configured
+client cert/key. If a list of CA names is provided,
+mod_ssl
will iterate through that list, and attempt
+to find a configured client cert which was issued either directly by
+that CA, or indirectly via any number of intermediary CA certificates.
+The chain of intermediate CA certificates can be built from those
+configured with SSLProxyMachineCertificateChainFile
. The
+first configured matching certificate will then be supplied in
+response to the challenge.
If the list of CA names is provided by the remote server,
+and no matching client certificate can be found, no client
+certificate will be provided by mod_ssl
, which will
+likely fail the SSL/TLS handshake (depending on the remote server
+configuration).
Currently there is no support for encrypted private keys

The files in this directory must be PEM-encoded and are accessed through
-hash filenames. Additionally, you must create symbolic links named
-hash-value.N
. And you should always make sure this
-directory contains the appropriate symbolic links.
