 Our WordPress Multisite is located in https://our-site.com/wordpress but
 the homepage is just https://our-site.com/

 We see the issue that "Lost your Password" link on login screen is not
 using our site directory at all.

 Here's the relevant part of our wp-config.php

 {{{
 define('MULTISITE', true);
 define('SUBDOMAIN_INSTALL', true);
 define('DOMAIN_CURRENT_SITE', 'our-site.com');
 define('PATH_CURRENT_SITE', '/');
 define('SITE_ID_CURRENT_SITE', 1);
 define('BLOG_ID_CURRENT_SITE', 1);
 }}}

 If we set PATH_CURRENT_SITE to /wordpress/ then the "Lost your Password"
 link works, but the wp-admin/network pages won't open. They end up in an
 endless loop because of $redirect_network_admin_request in wp-
 admin/network/admin.php

 Here's our '''quick fix''' to be put into wp-content/mu-plugins (you need
 to specify your WP directory as a path there):
 https://gist.github.com/foliovision/52e8a2bc5ae68eb73844

 ----

 The problematic function is '''network_admin_url()''' and the fact that it
 doesn't count on putting WordPress into a directory at all. It's using the
 global variable $current_blog which is initialized in ms-settings.php. The
 variable should not only store the path to the site front-end, but also
 the WordPress directory, so that it can reference individual PHP files
 properly.

 Similar bug is recorded here, but it's for WordPress 3.5: #23221
