saml令牌解析器無法解析令牌引用

我目前正在研究一個小型ASP.NET項目，涉及針對第三方身份提供者的用戶身份驗證。我在SP發起的SLO請求方面遇到問題。saml令牌解析器無法解析令牌引用

我正在使用WIF SAML 2.0 extension來處理SAML協議。

調試時我的應用程序立即崩潰，給我下面的錯誤信息（我刪除RAWDATA的，所使用的x509證書的公鑰對簽名值）：

The token resolver is unable to resolve the token reference 'SecurityKeyIdentifier 
    (
    IsReadOnly = False, 
    Count = 1, 
    Clause[0] = X509RawDataKeyIdentifierClause(RawData =) 
    ) 
'. 

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    )

如果我註釋掉KeyDescriptor在SP元數據的簽名證書，應用程序不會崩潰。但是，當我嘗試註銷時，我收到以下例外情況：

ID4450：類型爲「LogoutRequest」的消息在發送之前必須進行簽名。設置消息的SigningCredentials屬性，或者使用非空X509Certificate2配置Saml2MessageDecorator。

我不認爲WIF支持未簽署的SLO請求，所以我必須簽署它們。由於我無法理解的原因，似乎SecurityTokenResolver無法解析用於在元數據中定義的簽名的X509Certificate。

任何指針將深受讚賞。

解決它：
的問題是因爲證書是如何工作的認識不足朵朵：我試圖使用相同的X509證書籤署雙方IDP和SP的消息。

我created a X509Certificate並把它放在我的電腦的「個人商店」。下面的變化做是爲了在web.config：

<microsoft.identityModel> 
    <service> 

     <serviceCertificate> 
     <certificateReference 
      storeName="My" 
      x509FindType="FindByThumbprint" 
      storeLocation="LocalMachine" 
      findValue="82581cf4710c951d0f2e89e97c3a41d2b4a18890" 
     /> 
    </serviceCertificate> 
[...]

證書的Base64編碼的版本放在SP-元數據。 SecurityTokenHandler然後能夠簽署我的LogoutRequests。
