Question

C# code     

> error--->>>Unknown name. (Exception from HRESULT: 0x80020006
> (DISP_E_UNKNOWNNAME))

，代码就是这个

using (DirectoryEntry entry = new DirectoryEntry("LDAP://admin-jyt69gl7t.hello/CN=Users,DC=hello"))
{
    entry.Username = username;
    entry.Password = strOldPassword;

    DirectorySearcher searcher = new DirectorySearcher(entry);

    try
    {
        searcher.FindOne();
        entry.AuthenticationType = AuthenticationTypes.Secure;
        entry.Invoke("ChangePassword", new object[] { strOldPassword, strNewPassword });
        //  oDE.Invoke("SetPassword", new object[] { strNewPassword });
        entry.CommitChanges();
    }
    catch (Exception excep)

我收到此异常

> Unknown name. (Exception from HRESULT: 0x80020006
> (DISP_E_UNKNOWNNAME))

只需按照

下的代码操作即可

using System.DirectoryServices;


private DirectoryEntry GetUser(string UserName)

{

    DirectoryEntry de = GetDirectoryObject();
    DirectorySearcher deSearch = new DirectorySearcher();
    deSearch.SearchRoot = de;

    deSearch.Filter = "(&(objectClass=user)(SAMAccountName=" + UserName + "))";
    deSearch.SearchScope = SearchScope.Subtree;
    SearchResult results = deSearch.FindOne();

    if (!(results == null))
    {
       // **THIS IS THE MOST IMPORTANT LINE**
       de = new DirectoryEntry(results.Path, "username", "password", AuthenticationTypes.Secure); 
       return de;
    }
    else
    {
       return null;
    }
}

private DirectoryEntry GetDirectoryObject()

{

    DirectoryEntry oDE;
    oDE = new DirectoryEntry("LDAP://192.168.1.101", "username", "password", AuthenticationTypes.Secure);
    return oDE;
}


 public static bool ChangePassword(string UserName, string strOldPassword, string strNewPassword)

        {

            bool passwordChanged = false;

            DirectoryEntry oDE = GetUser(UserName, strOldPassword);

            if (oDE != null)
            {
                try
                {
                    // Change the password.
                    oDE.Invoke("ChangePassword", new object[] { strOldPassword, strNewPassword });
                    passwordChanged = true;
                }
                catch (Exception ex)
                {
                    Debug.WriteLine("Error changing password. Reason: " + ex.Message);

                }
            }
            return passwordChanged;
        }

Answer 2

此错误表示您未通过LDAP查询找到该用户。检查找到用户的代码，然后再次运行查询。

Answer 3

DISP_E_UNKNOWNNAME使得活动目录看起来响应尝试，但它无法根据目录条目中提供的名称找到用户。要尝试/验证的一些事情：

验证您的目录条目是否填充了正确的信息。
确认您的条目的用户名确实存在于AD中。
验证用户名所属的OU是否反映在您的查询中。

我以前收到过这个错误，并且普遍（对我而言）它围绕着目录条目与AD中用户的最终位置之间的脱节。 OU差异可以决定是否建立联系。
