НАЗВАНИЕ
login.defs - содержит конфигурацию подсистемы теневых паролей
ОПИСАНИЕ
The /etc/login.defs file defines the site-specific configuration for the shadow password suite. This file is required. Absence of this file will not prevent system operation, but will probably result in undesirable operation.
Файл представляет собой обычный текстовый файл; каждая строка описывает один параметр настройки. Строки состоят из названия параметра и его значения, которые разделяются пробельным символом. Пустые строки и комментарии игнорируются. Комментарии начинаются со знака фунта «#», который должен быть первым непробельным символом в строке.
Parameter values may be of four types: strings, booleans, numbers, and long numbers. A string is comprised of any printable characters. A boolean should be either the value yes or no. An undefined boolean parameter or one with a value other than these will be given a no value. Numbers (both regular and long) may be either decimal values, octal values (precede the value with 0) or hexadecimal values (precede the value with 0x). The maximum value of the regular and long numeric parameters is machine-dependent.
Возможны следующие параметры настройки:
PASS_MAX_DAYS, PASS_MIN_DAYS and PASS_WARN_AGE are only used at the time of account creation. Any changes to these settings won't affect existing accounts.

ОШИБКИ РЕАЛИЗАЦИИ
Much of the functionality that used to be provided by the shadow password suite is now handled by PAM. Thus, /etc/login.defs is no longer used by passwd(1), or less used by login(1), and su(1). Please refer to the corresponding PAM configuration files instead.
