IdentityServer4, WindowsCryptographicException: 系统找不到指定的文件

Question

我创建了一个包含多个客户端应用程序的 IdentityServer4 项目。我使用自签名证书文件 my_certificate.pfx 来生成登录令牌。它在本地主机上运行良好。

但是，将其用于共享网络托管服务器时，它不起作用。

承载 IdentityServer4 的应用运行正常，表明服务器应用可以访问证书文件。但是，尝试从客户端应用程序登录时会生成以下错误：

如何让客户端应用正常运行？

谢谢

我在 AWS ElasticBeanstalk 基础设施上设置 IdentityServer 并使用本地文件而不是证书存储时遇到了这个问题 - 但我的解决方案是相同的。我发现 EC2 实例上的应用程序池没有将 Load User Profile 设置为 true。设置后，权限模型会更改并允许进程加载到证书中。您可以通过应用程序池详细信息上的 IIS 管理 UI 启用，或使用下面的脚本版本。

Import-Module WebAdministration
Set-ItemProperty "IIS:\AppPools\DefaultAppPool" -Name "processModel.loadUserProfile" -Value "True"
