Hello & happy new year!

my goal is to configure nginx to deny access from most client-ip but allow 
access from special ip's
for authenticated users. This work for basic_authentication as expect but 
behave different with auth_ldap
I use https://github.com/kvspb/nginx-auth-ldap.

simplified configuration with no allowed IPs at all:

        server {
          listen *:80;
          deny all;
          location /auth_basic {
            auth_basic "auth_basic";
            auth_basic_user_file /path/to/auth_basic_user_file;
          }
        }

$ curl -v               http://nginx/auth_basic
$ curl -v -u user:pass  http://nginx/auth_basic
$ curl -v -u user:wrong http://nginx/auth_basic

all three calls return "403 Forbidden", which is ok and acceptable to me.

switching to auth_ldap the results are different:

        ldap_server ldap-server {
          url ldap://ldap-server/dc=example?cn?sub?(objectclass=top);
          require valid_user;
        }
        server {
          listen *:80;
          deny all;
          location /auth_ldap {
            auth_ldap "auth_ldap";
            auth_ldap_servers "ldap-server";
          }
        }

$ curl -v               http://nginx/auth_ldap
$ curl -v -u user:wrong http://nginx/auth_ldap
        return "401 Unauthorized"       expected: "403 Forbidden"

$ curl -v -u user:pass  http://nginx/auth_ldap
        return "403 Forbidden"

Is there anything wrong with my configuration or is the unexpected request for 
authentication
a result of how https://github.com/kvspb/nginx-auth-ldap is written?

        -> return "403 Forbidden"
