Внезапно я не могу войти с правильным паролем (greeter & tty)

Это может быть дубликат других вопросов, связанных с паролями, но это как-то эксцентрично.

У меня есть 3 аккаунта в моей системе Ubuntu 12.10 (один стандартный и два администратора). Одна из учетных записей администратора – это моя основная учетная запись разработки, и неожиданно позавчера она начала действовать странно (поскольку последние обновления – ядро ​​и другие:

  • На этапе greeter , когда я ввожу свой пароль, он мгновенно возвращает «Неверный пароль». Он даже не проверяет. (NB: пароль абсолютно правильный)
  • В TTY невозможно войти в систему, как только я введу свое имя для входа, а затем пароль, он мгновенно запросит меня ввести имя для входа … Похоже, что путь аутентификации этой учетной записи был случайно заблокирован или закрыт печатью.

Я вошел в систему со своей второй учетной записью администратора и сменил пароль для беспокойной учетной записи, но не повезло, вернул пароль обратно к исходному значению и установил учетную запись для автоматического входа в систему. перезагружается, а затем, действительно, учетная запись зарегистрирована. Тем не менее, аномалия остается:

  • Я не могу выполнять действия привилегии root (sudo & gksudo) . Как только я введу свой пароль, ничего не происходит. Единственный раз, когда пароль принимается, – это когда экран заблокирован и мне предлагается ввести пароль, чтобы разблокировать его.

Я проверил право собственности на свою домашнюю папку, и все в порядке. Некоторая помощь очень ценится.

Итак, чтобы подвести итог: – Не удается войти через lightdm – sudo, gksudo & pkexec не удастся – команда su не работает – если я предоставляю команду sudo с неправильным паролем, он проверяет и возвращает «Пароль неверно», но если я предоставляю правильный пароль, он ничего не возвращает. – Ключ пароля принимается, когда я автологин. – Пароль принимается при разблокировке экрана.

  • Я уже изменил пароль и проверил, принадлежит ли мое имя к таким группам, как (sudo, admin, adm, ….).

в x-2 log, код возврата аутентификации для пользователя hanine равен 19 (сбой), а администратор – 0 (успех).

Задача решена.

Вот действия, которые я выполнил до того, как проблема была решена:

  • sudo ppa-purge ppa: gnome3-team / gnome3 (чтобы вернуться к поддерживаемым пакетам gnome, таким как nautilus, … и т. д.),

  • создание каталога: / var / lib / samba и добавление себя к паролям samba databse ( sudo mkdir -p / var / lib / samba && sudo smbpasswd -a myusername

  • sudo pam-auth-update (все модули аутентификации были уже выбраны, поэтому я просто сделал клик в порядке).

Устранение неполадок здесь: http://ubuntuforums.org/showthread.php?t=2115288

Я сделал chmod 555 в моей домашней папке, которая создала проблему. Решение заключается в том, чтобы изменить права доступа с помощью чужого ноутбука.

 ssh (your laptop username)@(your IP) cd .. chmod 777 (your username on laptop)
