Jak sklonować użytkownika w SQL Server 2008 R2?

Czy istnieje sposób na klonowanie bezpieczeństwa użytkowników i uprawnień w Microsoft SQL Server, najlepiej przy użyciu graficznego interfejsu użytkownika SQL Server Management Studio?

Uwaga: Poniższy skrypt nie ustawia uprawnień do niczego, po prostu tworzy skrypt, który można skopiować i wkleić do nowego zapytania, które można następnie edytować przed uruchomieniem.

Poniższy skrypt pomoże Ci skopiować / sklonować uprawnienia jednego użytkownika innemu:

--- To copy permissions of one user/role to another user/role.

Oto bardzo fajny skrypt autorstwa Pawła Pawłowskiego do wykonania zadania: http://www.pawlowski.cz/2011/03/cloning-user-rights-database/

Główna zaleta:

• skrypt / kopia Rola Członkostwo
• skrypt / kopia Uprawnienia na poziomie obiektu
• skrypt / kopia Uprawnienia na poziomie bazy danych

NIE jestem autorem tego skryptu. Skrypt jest wklejany z tego linku na blogu Pawła Pawłowskiego, zobacz link, aby uzyskać więcej informacji na temat korzystania ze skryptu.

1. Baza danych prawym przyciskiem myszy w Eksploratorze obiektów
2. Zadania-> Generuj skrypty ...
3. Wybierz sekcję Tylko użytkownicy i zakończ działanie kreatora bez zmian

Uwaga: w końcu otrzymujesz skrypt do tworzenia wszystkich użytkowników i ich ról prawie gotowe. ale to nie utworzy skryptu do przyznawania uprawnień do wykonywania procedur przechowywanych, nawet jeśli wybierzesz opcję Uprawnienia do poziomu skryptu na wartość true.

W oparciu o niesamowitą odpowiedź @ Kin-shah napisałem skrypt, który może kopiować uprawnienia wszystkich baz danych w jednej instancji serwera SQL. Jest znacznie gorzej czytelny, ale może się przydać, jeśli masz wielu użytkowników i wiele baz danych:
