Nginx with auth_request and auth_basic

问题:

I can't seem to get this to work. According to the docs they can be used together.

Nginx Version: 1.10.3 --with-http_auth_request_module

location ~ ^/test(/.*|$) {
    satisfy any;
    auth_basic "test";
    auth_basic_user_file .htpasswd;
    auth_request auth.php;
}

My .htpasswd is blank. I want the username/password input in the basic form to be passed to my auth.php file. With this config when accessing /test I can see the subrequest made directly to auth.php. It never does a basic auth prompt. If I comment out auth_request auth.php the basic auth prompt does show. The doc does say to use satisfy any when using multiple auth modules.

There is an exact similar question with an answer, but it doesn't seem to work.

If anyone has gotten this to work can you help me out here?
