SAML2使用Thinktecture和WCF

我正在使用Thinktecture IdentityServer和WCF服务设置SAML2 STS。 我们的想法是让Thinktecture提供随后在WCF服务中使用的断言。

现在，我使用SAML 11 Assertions运行得很好 - urn：oasis：names：tc：SAML：1.0：assertion

断言是这样的：

<saml:Assertion MajorVersion="1" MinorVersion="1" AssertionID="_4e06770b-7fa0-425f-a4f3-263710f135d7" Issuer="https://localhost:123" IssueInstant="2014-01-18T16:16:38.099Z" xmlns:saml="urn:oasis:names:tc:SAML:1.0:assertion">
- <saml:Conditions NotBefore="2014-01-18T16:16:37.662Z" NotOnOrAfter="2014-01-18T16:26:37.662Z">
- <saml:AudienceRestrictionCondition>
  <saml:Audience>https://localhost:44300/</saml:Audience> 
  </saml:AudienceRestrictionCondition>
  </saml:Conditions>
- <saml:AttributeStatement>
- <saml:Subject>
- <saml:SubjectConfirmation>
  <saml:ConfirmationMethod>urn:oasis:names:tc:SAML:1.0:cm:bearer</saml:ConfirmationMethod> 
  </saml:SubjectConfirmation>...

现在，要求是使用SAML2，而不是以前的版本。因此，在Thinktecture中更改令牌类型很简单，新的断言生成正常，并且被客户端选择得很好。

新SAML2断言：

<Assertion ID="_f9c48402-857a-4cc3-8525-1af307ef3a01" IssueInstant="2014-01-18T16:32:18.038Z" Version="2.0" xmlns="urn:oasis:names:tc:SAML:2.0:assertion">

  <DigestValue>Nib1Bs9jy13unYShm08EcncqFsOS5IwVuWQ4tGoe4Pg=</DigestValue> 
  </Reference>
  </SignedInfo> ...

但是当我们尝试通过传递新的asertion来消耗WCF时，我们得到了异常：

  • XmlException：无法使用'ValueType'的'urn：oasis：names：tc：SAML：2.0：assertion'命名空间读取'Assertion'元素中的标记，该命名空间为BinarySecretSecurityToken。如果预期此元素有效，请确保将安全性配置为使用指定了名称，名称空间和值类型的标记

以下是WCF web.config的摘录：

那么我们做错了什么？

我无法通过您的WCF配置 - 特别是因为大部分内容与问题无关。

您不需要在WCF中执行任何“特殊”操作以使用SAML2令牌 - 遵循此简单示例 - 然后重新集成到您的应用程序中：
