I figured out how to create the users and orginanzational units using the "Active DS Type Library."  

How do I assign the users as well as other OU's to an OU?

function GetComputerName: String;   ///   Returns the computer Name   ///
var
  buffer : array[0..MAX_COMPUTERNAME_LENGTH + 1] of Char;
  Size : Cardinal;
begin
  Size := Max_COMPUTERNAME_LENGTH + 1;
  Windows.GetComputerName(@buffer,Size);
  Result := StrPas(buffer);
end;

function GetDomainName : string;    ///   returns the Domain Name   ///
var
  err : Integer;
  buf : pointer;
  fDomainName: string;
  wServerName : WideString;
begin
  wServerName := GetComputerName;
  err := NetServerGetInfo (PWideChar (wServerName), 503, buf);
  if err = 0 then
    try
      fDomainName := PSERVER_INFO_503 (buf)^.sv503_domain;
    finally
      NetAPIBufferFree (buf)
  end;
      result := fDomainName;
end;


procedure TfrmNTRS.btnCreateAccountClick(Sender: TObject);
  ///   Creates the Organiztional units   ///
var
  Comp : IADsContainer;
  OrgUnit : IADsOU;
begin
  GetDomainName;
  try
    comp := GetObject('LDAP://' + GetDomainName) As IADsContainer;
    OrgUnit := comp.Create('OrganizationalUnit', 'OU=' + leClassName.Text) As IADsOu;
    OrgUnit.SetInfo;
  Except On E: EOleException Do
    Begin
      ShowMessage(E.Message);
    End;
  End;
