MOSS 2007 Search and Basic Authentication

During the weekend, I tried to start a MOSS crawl and during the crawl, the crawler would crawl only specific content and was giving an access denied message for most of the content. It took me sometime to figure out that MOSS crawl wouldn't work with Basic Authentication. I knew that it would work with Windows Authentication, but had no idea about this one. Once I changed it to Windows Authentication, the crawl was working properly. So finally the moral of the story is : Search crawl works only with Windows Authentication and nothing else (not basic and not forms definitely.....)
