I have an internal sharepoint site extended to an internet site. This internet site using FBA and the aspnetdb database. The internet site is setup to have anonymous access. I can login fine using an account in the database by clicking on the sign in link bypassing the ISA server.
ISA is configured as a reverse proxy for this site. When I try to sign in using the internet URL through ISA, I get redirected to the default page but I am not signed in. Any ideas an what to check?
