Hi ISAlist,
Title: Enabling ISA Firewall Forms-based Authentication (FBA) for OWA
Connections for both Internal and External Clients – Part 1
Author: Thomas Shinder
Summary: The ISA firewall’s forms-based authentication (FBA) feature is one of
the killer apps included with the ISA firewall. The ISA firewall’s FBA
capability enables the ISA firewall to generate the OWA log on form instead of
requiring the Exchange Server to generate the form. This is a tremendous
security boon because it enables you to force authentication at the ISA
firewall before any connections are forwarded to the Exchange Server. This
prevents the situation you see when simple packet filter based firewalls are in
front of the Exchange Server and FBA is enabled on the Exchange Server itself.
This latter configuration allows unauthenticated and unauthorized connection
attempts to the Exchange Server, sometimes with unpleasant results.
