Description (last modified by royduineveld@…)

The documentation says: "The special value off allows cancelling the effect of the auth_basic directive inherited from the previous configuration level." Link: http://nginx.org/en/docs/http/ngx_http_auth_basic_module.html#auth_basic

So this should work right?

http {
    auth_basic            "Restricted Area";
    auth_basic_user_file  /htpasswd;

    server {
        location / {
            
        }
        location /api {
            auth_basic off;
        }
    }
}

Or

http {
    server {
        auth_basic            "Restricted Area";
        auth_basic_user_file  /htpasswd;
        
        location / {

        }
        location /api {
            auth_basic off;
        }
    }
}

But at /api I'm still getting the basic authentication. It only works like this:

http {
    server {
        location / {
            auth_basic            "Restricted Area";
            auth_basic_user_file  /htpasswd;
        }
        location /api {
            auth_basic off;
        }
    }
}

So auth_basic can not be overwritten from another context. This also happens with allow/deny. Having this for example at http/server level:

allow 127.0.0.1;
deny all;

Can not be overwritten with allow all; for a specific location.
