Custom Login page for FBA cause Crawl Error in Sharepoint 2010

Hi Everyone,

When you use Sharepoint 2010 with Claim Based Authentication with both windows and forms based authetication , you may want to create custom login page than you think twice for search crawling. Last night i spend 3 hours for this problem and set back to login page to original login page after doing  that crawl completed successfully. I assume that sharepoint crawling account which is windows account can not connect site using windows authentication beacause of custom login page. (Login page code was written by the book and  it is working correctly (indeed it was another challege for me).

In my case i have to use this custom login page and also site must to be crawled . So i extended sharepoint site with new application which is also both windows and forms based authentication but using original login page. and configure sharepoint search for crawl for this app. And i alse defined a new alternet access mapping for this.
