使用PrincipalContext.ValidateCrendentials时，服务器无法处理目录请求 [英] The server cannot handle directory requests while using PrincipalContext.ValidateCrendentials

问题描述

 嗨

 使用PrincipalContext.ValidateCrendentials时出现以下异常

 I am getting the below exception while using PrincipalContext.ValidateCrendentials

我们尝试将ContextOptions设置为以下值，但我们仍然面临相同的例外.

Things Which we tried are setting up the ContextOptions to below values, Still We are facing the same exception.

ContextOptions.Negotiate | ContextOptions.Signing | ContextOptions.Sealing | ContextOptions.SecureSocketLayer

也出现了此错误仅适用于特定的机器/服务器 相同的代码对于其余的服务器都可以正常工作

可能的原因是什么这个问题对我们来说更像是服务器端的环境设置

推荐答案

您好，Jitendrapuri Gos wami，

根据您的描述，它适用于某些服务，但不适用于特定的机器/服务器，似乎是配置问题.

According to your description, it works for some of service, but not work for particular machine/server, it seems that it is a configuration issue.

请检查应用程序池的用户是否正在IIS上运行.

Please check the user of the app pool if this is running on IIS.

以下线程有一个类似的问题，事实证明服务器上的IIS已设置为以LocalMachine的身份运行.请将其更改为NetworkService(默认).

The following thread has a similar issue, which turned out that IIS on the server was set up to run as LocalMachine,  please change it to NetworkService (the default).

最诚挚的问候，
