Is it possible to use forms based authentication/.net security for a site collection? I can see where I can configure a web application for FBA, but not for a site collection, which in my case is a host named site collection. Is it possible for both FBA and windows authentication to be used for a site collection, the issue being that both internal and external users should access the site, but I don't care to use cross domain trusted solutions, add external users to my domain.
If possible, how?
