弱式簽章演算法錯誤

Microsoft.ActiveDirectoryFederationServices.2016.TokenIssuanceWeakSignatureAlgorithmErrorRule (Rule)

Knowledge Base article:

摘要

用於驗證使用者的權杖，或是透過預期的簽章演算法簽署要求。

原因

用來驗證使用者的權杖是使用較預期弱的簽章演算法進行簽署的。

解決方式

請確認宣告提供者已設為接受具有預期簽章演算法的權杖。若要解決此問題，您可以使用 AD FS 的 Windows PowerShell Cmdlet 或 AD FS 嵌入式管理單元重新設定簽章演算法。針對 Cmdlet 更新，請使用 Set-ADFSClaimsProviderTrust Cmdlet 的 SignatureAlgorithm 參數。針對 Microsoft Management Console (MMC) 式更新，您可以在宣告提供者信任內容的 [進階] 索引標籤上修改簽章演算法內容。
