Thread:Project:Support desk/Replacing login Page

Versions: MediaWiki: 1.22.6 PHP: 5.3.10 Database: MySQL 5.5.37

I would like to replace the authorization for access to the wiki with a separate web page. On this separate web page, the user will log in and, upon authorization, will receive access to a variety of tools, one of which is the wiki. The wiki needs to remain private, but I would like to remove the default authorization / login system that is built in to MediaWiki. If anyone could give me some pointers to get started with this that would be much appreciated.
