i use the simple way to solve this problem:

procedure TMainDm.QueryError(Sender: TObject; const ERRCODE: Integer;
ErrorMessage, ErrorCodes: TStringList; const SQLCODE: Integer;
SQLMessage, SQL: TStringList; var RaiseException: Boolean);
begin
case ERRCODE of
335544352: begin // insufficiently rights
RaiseException := False;
if (Sender is TIB_Query) then
try
TIB_Query(Sender).Close;
TIB_Query(Sender).InsertSQL.Clear;
TIB_Query(Sender).EditSQL.Clear;
TIB_Query(Sender).DeleteSQL.Clear;
TIB_Query(Sender).Open;
except
RaiseException := True;
end;
end;
end;
end;

and no more! no additional code is needed to manage user rights in app
