如何阅读AD displayname

标签: delphi active-directory pascal

我正在使用Delphi pascal ver。 4 我有一个用户首字母,需要从首字母获取活动目录显示名称 所以我不想改变AD只读 - 一个函数将是这样的好:

fullname, user :string;
user:='DKTB'

(通话功能)

fullname:=getAdDispayName(user);

(调用之后fullname ='Torben Bagge')

我使用谷歌找到它但只能在C中找到它而不是pascal。

您可以使用IDirectorySearch界面轻松完成此操作。我为你做了一个简单的例子(不要忘记添加适当的错误处理):

uses
  ActiveX,
  JwaAdsTlb, JwaActiveDS; // From Jedi ApiLib

function GetADDisplayName(const Username: String): String;
var
  hr: HRESULT;
  DirSearch: IDirectorySearch;
  SearchInfo: ADS_SEARCHPREF_INFO;
  hSearch: ADS_SEARCH_HANDLE;
  col: ADS_SEARCH_COLUMN;
  Filter: String;
  Attributes: array of PChar;
begin
  Result := 'Undefined Result';

  // Initialize COM
  CoInitialize(nil);

  try
    // Change line below with your domain name
    hr := ADsGetObject('LDAP://dc=contoso,dc=com',
      IID_IDirectorySearch, Pointer(DirSearch));
    Win32Check(Succeeded(hr));

    SearchInfo.dwSearchPref := ADS_SEARCHPREF_SEARCH_SCOPE;
    SearchInfo.vValue.dwType := ADSTYPE_INTEGER;
    SearchInfo.vValue.Integer := ADS_SCOPE_SUBTREE;

    hr := DirSearch.SetSearchPreference(@SearchInfo, 1);
    Win32Check(Succeeded(hr));

    Filter := Format('(&(objectClass=user)(sAMAccountName=%s))',
      [Username]);

    SetLength(Attributes, 1);
    Attributes[0] := 'displayName';

    // When using Dynamic Array with WinApi ALWAYS use pointer to first element!
    hr := DirSearch.ExecuteSearch(PChar(Filter), @Attributes[0],
      Length(Attributes), hSearch);
    Win32Check(Succeeded(hr));

    try
      hr := DirSearch.GetFirstRow(hSearch);
      Win32Check(Succeeded(hr));

      hr := DirSearch.GetColumn(hSearch, Attributes[0], col);
      if Succeeded(hr) then
      begin
        Result := col.pADsValues^.CaseIgnoreString;
        DirSearch.FreeColumn(@col);
      end;
    finally
      DirSearch.CloseSearchHandle(hSearch);
    end;
  finally
    // UnInitialize COM
    CoUninitialize;
  end;
end;
