红帽全球峰会8.5.6.2. Apache 证书查找供应商
当 Red Hat Single Sign-On 服务器位于 Apache 反向代理后面时，您可以使用此供应商。为您的服务器使用以下配置：
<spi name="x509cert-lookup">
<default-provider>apache</default-provider>
<provider name="apache" enabled="true">
<properties>
<property name="sslClientCert" value="SSL_CLIENT_CERT"/>
<property name="sslCertChainPrefix" value="CERT_CHAIN"/>
<property name="certificateChainLength" value="10"/>
</properties>
</provider>
</spi>
此配置与 haproxy 供应商相同。如需了解有关配置客户端证书和客户端证书链的 HTTP 标头的详细信息，请参阅 mod_ssl 和 mod_headers 上的 Apache 文档。
