Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingProvider[48]读取密钥环时出错

Question

这个问题只有当我在共享主机上部署ASPWebCore2.1Web应用程序时才会出现。我正在使用带有PersistKeysToFileSystem的Azure密钥库。

Web App在我的开发机器和Azure App上都工作得很好，无论有没有使用PersistKeysToFileSystem的Azure Key Vault。

Answer 1

我在安装Active Directory后遇到了这个问题，我的解决方案是将IIS应用程序池的"Load User Profile“设置为"True”。
