IIS привязка с проверкой подлинности Windows
У меня есть локальный веб-сайт (http://localhost/testsite) с проверкой подлинности Windows
- > работает хорошо
теперь я изменил привязку сайта к url (htt://testsite.blablabla.biz) с проверкой подлинности Windows
- > Ошибка HTTP 401.1 - Несанкционированный
У вас нет разрешения на просмотр этого каталога или страницы, используя предоставленные вами учетные данные.
Что я делаю неправильно? Я много искал в google, но ничего не помогает. Я думаю, что это имеет какое-то отношение к DOMAINNAMES или чему-то, но я не уверен.
Кто может помочь?
Ответы
Ответ 1
У Windows есть функция безопасности для выполнения проверок на проверку, которая призвана предотвращать атаки отражения на вашем компьютере.
Когда вы используете собственный заголовок хоста для просмотра локального веб-сайта, размещенного на компьютере под управлением IIS, вы получите это сообщение об ошибке, если веб-сайт использует проверку подлинности Windows и имеет имя, сопоставленное локальному адресу loopback.
Существует два способа решения этой проблемы:
1) Укажите имена хостов или
2) Отключите проверку обратной связи
Microsoft KB Код статьи: 896861
Ответ 2
Обратите внимание, что, изменив привязку, этот веб-сайт не может быть снова доступен вашим предыдущим URL-адресом в веб-браузерах. Узнайте о том, что является обязательным, и вы должны выяснить, не сделали ли вы что-то неправильно.
Таким образом, сайт, который дает вам этот 401.1, может быть совершенно другим сайтом.
Ответ 3
Вот командные файлы PowerShell, которые я написал для управления настройками проверки петли. Он включает в себя код, который пытается получить имена хостов для всех веб-сайтов IIS, использующих проверку подлинности Windows, и устанавливает имена хостов с обратным подключением.
