Опция 'unix password sync' была введена специально для возможности плавного перехода на криптованную передачу паролей без того, чобы заставлять каждого юзера, имеющего accont на unix-тачке еще раз вводить свой пароль в smbpasswd.
Работает эта опция при отключенном 'encrypt passwords', и Самба, после проверки на корректность пароля пользователя по /etc/passwd (/etc/master.passwd) сама генерит smbpasswd. Так что спустя разумное время, за который каждый хотя бы раз залогинился, можно безболезненно включать 'encrypt passwords', не подводя юзеров (коих может быть сотни) поочередно к консоли.
"Синхронизация" же путем "перетаскивания" паролей из /etc/passwd (/etc/master.passwd) в smbpasswd, как уже говорил Andrey Zakharchenko, требует изрядного машинного времени... :)
Samba and WinNT
All versions of Windows NT prior to 4.0 Service Pack 3 could negotiate plain text (clear text) passwords. Windows NT 4.0 Service Pack 3 changed this default behaviour so it now will only handle encrypted passwords. The following registry entry change will re-enable clear text password handling:
Run regedt32.exe and locate the hive key entry: HKEY_LOCAL_MACHINE\system\CurrentControlSet\Services\Rdr\Parameters\
Add the following value:
EnablePlainTextPassword:REG_DWORD=1
При этом все равно на Linux придется проводить дополнительную перерегистрацию пользователей - не только командой passwd, но и smbpasswd - генерящую самбовские пароли.
у Самбы с настройками по умолчанию скрость записи была в 3 раза больше чем чтения: Лечим: socket options = IPTOS_LOWDELAY TCP_NODELAY Параметр logon path ИЗ smb.conf
Linux samba for WinNT
When Samba is configured with the 'security = server' option and the 'password server = Your_Windows_NT_Server_Name' option, then it will redirect all access authentication to that server. This way you can use Windows NT to act as your password server with full support for Microsoft encrypted passwords.
Note also, that since release of samba-1.9.18 we now support native encrypted passwords too. To enable encrypted password handling several things need to be done:
1) In smb.conf [globals]:
encrypt passwords = yes
smbpasswd file = /path/smbpasswd the standard path is /usr/local/samba/private/smbpasswd but this may be platform specific.
2) Use "smbpasswd -a" to add all users to the smbpasswd file.
