MediaWiki Login Page for Non Logged In Users

Is there a way to make a login page that just asks for user/pass for MediaWiki so they don't see the sidebar or a page that says they have to login to开发者_开发问答 view the content?

Any links to examples and/or tutorials would be awesome, I couldn't find anything.
