What I have?
I have a SharePoint 2010 web application with FBA configured and it is exposed to Internet. The root site collection has a huge hierarchy and each site has document libraries with many documents.
There are more than 10 site groups defined and some of them has access only to some sites.
What problem am I facing?
Everything was working fine and suddenly I am facing a problem in Enterprise Search.
When a user searches, the search result displays everything (including the site where user does not have permission) and clicking on a result it either opens the item (page/document) or shows Access denied error depending on whether the user has permission on that item.
Can someone tell me why is this happening?
