Я пытаюсь создать репозиторий git на нашем офисном сервере и сделать его доступным через SSH с использованием аутентификации с открытым ключом. Я создал пользователя git на сервере и добавил два открытых ключа OpenSSH в ~/.ssh/authorized_users.
Я могу успешно подключиться, используя ssh git@xxx.xxx.xxx.xxx. При попытке связаться с ssh ssh://git@xxx.xxx.xxx.xxx аутентификация с открытым ключом не выполняется, и соединение возвращается к аутентификации по паролю; однако пароль пользователя git также не аутентифицируется. То же самое справедливо и при попытке подключения от другого пользователя на сервере (ssh ssh://git@localhost).
Кто-нибудь знает способ конфигурации, который может вызвать такое поведение?
Сервер представляет собой Mac Mini под управлением OSX 10.6.8 с установленным по умолчанию OpenSSH.
