Spring Security SAML-如何配置客戶端身份驗證？

Question

我正在嘗試使Spring Security SAML示例應用程序改用測試IDP（由其他人提供）代替ssocircle。 單擊“ SAML登錄”正確地將我重定向到IDP的SSO登錄頁面，但是登錄並重定向回到示例應用程序后，我得到了一個異常（顯然是在工件解析期間），其根源是：

org.opensaml.ws.message.decoder.MessageDecodingException: Error when sending request to artifact resolution service.
    at org.springframework.security.saml.websso.ArtifactResolutionProfileImpl.getArtifactResponse(ArtifactResolutionProfileImpl.java:110)

經過一會兒的挖掘，我意識到服務器希望在相關端口進行客戶端身份驗證。 如果我以這種方式連接到它，則會得到一個有效的響應：

curl -k --cert spcert.pem --key spkey.pem https://testidp:8110/idp/profile/SAML2/SOAP/ArtifactResolution

另外，如果我通過編輯IDP tomcat的server.xml並在相關的<Connector>標記中將clientAuth更改為“ false”來禁用IDP上的clientAuth，則該異常消失。

如果我像這樣使用apache httpclient，則連接到IDP的端口8110可以正常工作

}

但是，我不知道如何正確配置Spring SAML的TLSProtocolConfigurer（或使用客戶端密鑰所需的一切）。

那么，如何告訴Spring Security SAML在TLS / SSL連接中使用我的客戶端密鑰進行客戶端身份驗證？

Answer 1

好的，了解了如何在Spring SAML的TLS連接中啟用clientAuth。 這是來自securityContext.xml的我的服務提供者配置：

<bean class="org.springframework.security.saml.metadata.ExtendedMetadataDelegate">
    <constructor-arg>
        <bean class="org.opensaml.saml2.metadata.provider.FilesystemMetadataProvider">
            <constructor-arg>
                <value type="java.io.File">classpath:metadata/sp.xml</value>
            </constructor-arg>
            <property name="parserPool" ref="parserPool" />
        </bean>
    </constructor-arg>
    <constructor-arg>
        <bean class="org.springframework.security.saml.metadata.ExtendedMetadata">
            <property name="local" value="true" />
            <property name="signMetadata" value="true" />
            <property name="signingKey" value="mykey" />
            <property name="encryptionKey" value="mykey" />
            <property name="tlsKey" value="mykey" />
        </bean>
    </constructor-arg>
</bean>  

通過<property name="tlsKey" value="mykey" />設置客戶端密鑰可以啟用ClientAuth

必須像往常一樣在JKSKeyManager中聲明密鑰：

<bean id="keyManager" class="org.springframework.security.saml.key.JKSKeyManager">
    <constructor-arg value="classpath:security/keystore.jks" />
    <constructor-arg type="java.lang.String" value="secret" />
    <constructor-arg>
        <map>
            <entry key="mykey" value="secret" />
        </map>
    </constructor-arg>
    <constructor-arg type="java.lang.String" value="mykey" />
</bean>

這在本文的文檔中被稱為“用於SSL / TLS客戶端身份驗證的填充憑據。如果ExtendedMetadata指定屬性tlsKey，它將用作別名，以從keyManager bean查找密鑰。否則，將不提供用於身份驗證的憑據。” 花了我一段時間才找到;-)
