nginx auth_request 被忽略

Question

为什么我的 auth_request 被完全忽略？

nginx.conf

server {
        listen 80;
        error_page 403 = @error;

        location = /auth {
                return 403;
        }

        location /api {
                auth_request /auth;
                return 201;
        }

        location /test {
                return 200;
        }

        location @error {
                return 500;
        }
}

我尝试了不同的版本，1.8、1.15.12、1.16.0，但没有运气 - 这只是调试和 http_auth_request

不确定是否重要，但我正在 rhl 6.1 上运行，内核为 2.6.32-754.10.1.el6.x86_64
