Файловый сервер SAMBA

• Samba
• Включаем отображение Samba-сервера в сетевом окружении Windows

# apt install samba

# cat /etc/samba/smb.conf

Добавляем пользователей user1 и user2 на server (Управление учетными записями в Linux)

!!! smbd должен быть запущен!!!

server# smbpasswd -a user1
New SMB password: wpassword1

server# (echo wpassword2; echo wpassword2) | smbpasswd -a user2

# pdbedit -w -L

# smbpasswd -x user1

Устанавливаем Microsoft Windows Support Tools

Авторизация в режиме ADS (Сервис WINBIND)

Примечание: достаточно зарегистрировать SAMBA сервер в домене, принципал cifs не нужен

Авторизация в режиме DOMAIN (Сервис WINBIND)

gate# cat /etc/samba/smb.conf
