Почему администраторская страница CUPS OpenWRT запрашивает вход в систему и не возьмет пользователя/пароль при добавлении принтера?

Я использую OpenWRT 14.07 с CUPS 1.5.4. Когда я пытаюсь добавить принтер, UI приводит меня через весь рабочий процесс, пока я не добираюсь в конец. В конце рабочего процесса, после того, как я нашел принтер, добавили описания, указанные драйверы, и т.д. Я нажимаю на "Add Printer".

В этой точке администратор CUPS UI отправляет мне Основной Подлинный запрос, просящий имя пользователя и пароль в области "CUPS":

Имя пользователя и пароль требует http://192.168.0.1:631. Сайт говорит: "CUPS"

Я не могу заставить администраторский сайт принимать любую комбинацию имени пользователя/пароля. Я видел это прежде на различных экранах и ввел "корень" / "пароль" и UI приняли его там. Я играл вокруг с установкой с тех пор, и теперь единственное время, мне предлагают имя пользователя, и пароль - когда я нажимаю на "Add Printer".

Я пытался добавить принтер вручную путем прямого редактирования "printers.conf" (против совета и из отчаяния). Теперь принтер появляется, но задания просто исчезают. (Я предполагаю, что совет был убедителен, и некоторый шаг установки очереди не произошел), "ручное поведение принтера может быть другим вопросом, но применимое наблюдение здесь состоит в том, что "Изменяют Принтер", теперь имеет то же поведение пароля.

Я плохо знаком с CUPS (на этом уровне) и OpenWRT, но я использовал Linux в течение 15-20 лет, и лично и профессионально и в ПК и встроил среды.

Любая справка ценится. Мои конфигурации присоединяются. Я искажал их, чтобы попытаться обойти эту проблему некоторое время.

Мне нужно было создать пользователя и группу «lp», а также группу «lpadmin».
Затем я установил поля User и Group в файле конфигурации на

User = lp. Group = lp

После этого OpenWrt перестал спрашивать мой пароль и позволил мне завершить настройку принтера. Я считаю, что дистрибутив CUPS 1.5.4 ошибочно принял ошибку отказа в разрешении для файлов cups как ошибку авторизации пользователя веб-пользователя, что привело к возникновению этой проблемы.
