Moss 2007 Search in Forms Authentication Mode

The out of box feature of Moss 2007 search doesn't works in Forms authentication mode.
To get rid of this problem
go to central administration ->application management ->Create or Extend Web Application
click on 'Extend an existing Web application' select the web application for which you enabled forms authentication.
create a new IIS Website with zone as Intranet. for ex: http://systemname:1234/
now go to shared service administration, create new shared service provider(SSP).
go to SSP->search settings click on Content sources and crawl schedules, click on link
Local Office SharePoint Server sites. In the site addresses box add Intranet site(http://systemname:1234/)
check start full crawl of this content source checkbox and click on ok. It take few minutes to crawl all content of your Site.
That's it now you can search forms word in your forms authentication site.....
To crawl the new content of the site you can set the incremental crawl duration in Local Office SharePoint Server sites.
