Active Directory Linqpad与Visual Studio

Question

我需要针对Active Directory对用户进行身份验证。相同的代码在Visual Studio和LinqPad中运行。 LinqPad工作正常但是在Visual Studio中，它出现了一个非常有用的未知错误，堆栈跟踪如下：

System.DirectoryServices.Protocols.LdapException: A local error occurred.    
     at System.DirectoryServices.Protocols.LdapConnection.BindHelper(NetworkCredential newCredential, Boolean needSetCredential)    
     at System.DirectoryServices.AccountManagement.CredentialValidator.lockedLdapBind(LdapConnection current, NetworkCredential creds, ContextOptions contextOptions)    
     at System.DirectoryServices.AccountManagement.CredentialValidator.BindLdap(NetworkCredential creds, ContextOptions contextOptions)    
     at System.DirectoryServices.AccountManagement.CredentialValidator.Validate(String userName, String password)    
     at System.DirectoryServices.AccountManagement.PrincipalContext.ValidateCredentials(String userName, String password)

两者中的代码仅在LinqPad中运行：

using (System.DirectoryServices.AccountManagement.PrincipalContext pc = new System.DirectoryServices.AccountManagement.PrincipalContext(System.DirectoryServices.AccountManagement.ContextType.Domain))
{
   return pc.ValidateCredentials("SomeName", SomePassword");
}

我还使用/不使用Admin在VS之外运行了exe，并且还使用了cmd行的runas。 如果有人知道为什么这些行为会有所不同，那么我们将非常感激。

尝试将代码更改为此我在本地远程服务器上尝试了这一点，并且都在工作

  

如果用户为空，则表示在AD

中找不到它们

string fullName = null;
using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
{
    using (UserPrincipal user = UserPrincipal.FindByIdentity(context,"your domain username goes here"))
    {
        if (user != null)
        {
            fullName = user.DisplayName;
        }
    }
}
