I have published my exchange 2007 CAS through ISA 2006 with single network. The ISA is inside our network and is joined to the domain .I created a web listener and Publishing rule, I test the rule and everything seems ok. FBA is disabled on the CAS. However, each time i want to access my site internally, I am presented with basic/standard authentication instead of the FBA authentication configured on the ISA server. Please help I want to use FBA on the ISA 2006 sp1.
