Question

我写了一个C＃程序来连接MySql服务器和＆＃39; Mysql Connector/Net＆＃39;。我使用ssl选项的安全连接。我太正确地制作了服务器证书和客户端pfx证书。但是当我试图连接到服务器时，我得到了这个例子。

    System.Security.Authentication.AuthenticationException: A call to SSPI failed, see inner exception. ---> System.ComponentModel.Win32Exception: The Local Security Authority cannot be contacted
   --- End of inner exception stack trace ---
at System.Net.Security.SslState.StartSendAuthResetSignal(ProtocolToken message, AsyncProtocolRequest asyncRequest, Exception exception)
at System.Net.Security.SslState.CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest)
at System.Net.Security.SslState.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest)
at System.Net.Security.SslState.ProcessReceivedBlob(Byte[] buffer, Int32 count, AsyncProtocolRequest asyncRequest)
at System.Net.Security.SslState.StartReadFrame(Byte[] buffer, Int32 readBytes, AsyncProtocolRequest asyncRequest)
at System.Net.Security.SslState.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest)
at System.Net.Security.SslState.CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest)

at System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest)
at System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResult lazyResult)

我使用的MySql Connector / Net版本支持MySql服务器版本（5.5）（6.9）。

重要提示：它在早期的Windows 10中有效，但在Windows 10中却不是最新的。我的朋友在Windows 7和8.1中成功测试了它。也许Windows更新搞砸了。

我读了here解决方案：必须编辑注册表，但它不起作用。

Answer 1

我遇到了同样的问题，我认为它与Windows 10的最新安全更新有关。当我将连接字符串更改为我的连接的SSL加密时，错误消失了... 编辑：更新mysql-server-5.5后错误解决

C＃对SSPI的调用失败，请参阅内部异常 - 无法联系本地安全机构
