CMD LDAP错误无法连接到LDAP服务器，但通过C＃代码成功连接

Question

编辑：IMO，这应该发布在Serverfault中，所以我created one并投票决定在Stackoverflow中关闭它。

我尝试搜索并使用命令行来测试与LDAP服务器的连接，但是即使在我的本地计算机上，它也会引发错误“无法连接到LDAP服务器”

我使用Visual Studio在本地计算机上调试代码并成功连接吗？

所以how to connect to LDAP serrver using cmd for windows 10?

Cmd错误：

ldapsearch -x -h LDAP://adserverxx.xx -p 389 -D "cn=ldap,dc=test" -w passxx "objectclass=*"

代码C＃run ok and successfully authenticated（ASP.NET）

bool bSucceeded;
string strAccountId = "ldap";
string strAccountPas = "inxxx";
string strError = "";
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://serveraddxx:389", strAccountId, strAccountPas);
using (DirectorySearcher adsSearcher = new DirectorySearcher(directoryEntry))
{
    //adsSearcher.Filter = "(&(objectClass=user)(objectCategory=person))";
    adsSearcher.Filter = "(sAMAccountName=" + strAccountId + ")";

    try
    {
        SearchResult adsSearchResult = adsSearcher.FindOne();
        bSucceeded = true;

        string strAuthenticatedBy = "Active Directory";
        strError = "User has been authenticated by Active Directory.";
    }
    catch (Exception ex)
    {
        // Failed to authenticate. Most likely it is caused by unknown user
        // id or bad strPassword.
        strError = ex.ToString();
    }
    finally
    {
        directoryEntry.Close();
    }
}

P / S：我们今天（昨天可以）从托管服务器（Web应用程序）连接到ldap时遇到问题，它仅引发异常“找不到网络路径”。
