I have 5 site collections. One of the 5 site collections is a Search Center. The other 4 site collections I have set on anonymos access and that works. I dont get login popups. From these 4 site collections the end user can search in the search box, which will redirect to the search center site collection. After the end user try to search he gets the url from the search center url and then he will see a login popup!! I dont whant this login popup. How can I set the Search Center also on anonymos access.
