MediaWiki Аутентификация из внешней формы

Я уже установил mediawiki, но я хочу, чтобы пользователи аутентифицировались из внешней формы аутентификации. Когда они вводят правильное имя пользователя и пароль, они перенаправляются на страницу вики, и им не нужно повторно вводить данные для входа, и, следовательно, они могут идти редактировать вики так, как они хотят. Как мне этого добиться?

Используйте API медиавики с action=login . См. http://en.wikipedia.org/w/api.php.

Если у вас есть внешняя служба аутентификации, предоставляющая услугу веб-аутентификации, вы можете адаптировать некоторое расширение веб-аутентификации. Это один используется в моей организации. Конечно, вам придется настроить его.

Еще одним вариантом является вход OpenID с этим расширением, похоже на вход в систему через stackoverflow.

В этих двух решениях пароль не отправляется между «внешней формой» и вашей вики, а только токен, указывающий, что пользователь прошел вход в систему.
