将Spring SAML作为SP和SimpleSAMLphp集成为IdP（HoK配置文件）

我正在尝试使用Spring SAML作为SP和SimpleSAMLphp作为IdP使用HoK配置文件。

SP获取客户端证书，然后将以下身份验证请求发送到IdP而不会出现问题：

<?xml version="1.0" encoding="UTF-8"?>
<saml2p:AuthnRequest
    AssertionConsumerServiceURL="https://sp.com/saml/HoKSSO"
    Destination="https://localhost:8443/simplesaml/saml2   /idp/SSOService.php"
    ForceAuthn="false" ID="a5ba2704fgc63887442i9i1298904fh"
    IsPassive="false" IssueInstant="2015-10-04T11:26:47.393Z"
    ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST"

    <saml2:Issuer xmlns:saml2="urn:oasis:names:tc:SAML:2.0:assertion">https://sp.com/saml/metadata</saml2:Issuer>
</saml2p:AuthnRequest>

作为回应，IdP在TLS握手期间请求客户端证书，然后获取其用户名/密码并成功验证他。它发送以下响应：

一切似乎都没问题，但Spring SAML引发了以下异常：

错误是： HoK SubjectConfirmation因确认数据不是KeyInformationDataType类型而失效。似乎Spring SAML在响应中找不到KeyInfo !!

有人可以帮我解决这个问题吗？

谢谢

修改

通过与样本HoK SSO响应进行比较，它发现SimpleSAMLphp尚未将 xsi：type =“saml：KeyInfoConfirmationDataType”添加到SubjectConfirmationData标记。这可能是上述例外的原因吗？

它是SAML2.0 HoK配置文件中SubjectConfirmationData标记的必需属性吗？

1 个答案:

答案 0 :(得分：4)

最后我找到了解决方案：

SimpleSAMLphp不会将xsi：type =“saml：KeyInfoConfirmationDataType”添加到“SubjectConfirmationData”标记中，因为标准没有强制要求：

329  3.1 Holder of Key
330  URI: urn:oasis:names:tc:SAML:2.0:cm:holder-of-key
331  One or more <ds:KeyInfo> elements MUST be present within the <SubjectConfirmationData>
332  element. An xsi:type attribute MAY be present in the <SubjectConfirmationData> element and, if
333  present, MUST be set to saml:KeyInfoConfirmationDataType (the namespace prefix is arbitrary but
334  must reference the SAML assertion namespace).

我更改了simplesamlphp代码并手动添加了缺少的属性。 （我仍然不确定我是否在正确的位置添加，但它现在有效！） 但新问题是谁必须解决这个问题？ Spring SAML还是simpleSAMLphp？

通过此更改，Spring SAML检测到SubjectConfirmationData标记包含一个或多个元素，然后它找到嵌入在响应中的客户端证书，并尝试将其与在TLS客户端身份验证期间收到的证书进行比较。

尽管这两个证书是相同的，但是Spring SAML说它们不匹配，因为其中一个证书有断行而另一个证书没有。

我唯一剩下的问题是：

哪种方法与标准兼容？在base64编码的证书中添加断行或删除它们，甚至比较是否有断行？
