* authentication process used in the standard SSL handshake when a connection is established. In per-directory
* context it forces an SSL renegotiation with the reconfigured client verification level after the HTTP request was
* read but before the HTTP response is sent. <br>
* The following levels are available for level:
*
* <pre>
* SSL_CVERIFY_NONE - No client Certificate is required at all
* SSL_CVERIFY_OPTIONAL - The client may present a valid Certificate
* SSL_CVERIFY_REQUIRE - The client has to present a valid Certificate
* SSL_CVERIFY_OPTIONAL_NO_CA - The client may present a valid Certificate
* but it need not to be (successfully) verifiable
* </pre>
*
* <br>
* The depth actually is the maximum number of intermediate certificate issuers, i.e. the number of CA certificates
* which are max allowed to be followed while verifying the client certificate. A depth of 0 means that self-signed
* client certificates are accepted only, the default depth of 1 means the client certificate can be self-signed or
* has to be signed by a CA which is directly known to the server (i.e. the CA's certificate is under
