I am trying to setup an IdP Provider using OpenAM(OpenSSO) with a 3rd party SP. I currently have OpenAM behind Apache reverse proxy with OpenAM configured to use an internal DNS. When I access OpenAM through the proxy, OpenAM redirects to the internal DNS instead which cannot be resolved by the browser.
I've tried setting the com.sun.identity.server.fqdnMap[public.domain.com]=internal.domain.com property and even swapping the (in)valid values around.
What am I missing?
