Well.. I created the extention, switched my original site back to custom login page, added the extension to my content sources, reset the index, ran full crawl. My original was again not accessable but the new extension was crawled. Oddly though when I enter
the original site thru my custom login page I get 0 search results. Also when I enter thru the extension I get 0 search results. So now I'm confused. Should my results from the extension be available to users logged into the original site?
