We have the following configuration: Front-End/Back-End Setup Exchange 2003 SP1 Active/Passive Cluster for the BackEnd attached to DELL/EMC SAN Single Exchange 2003 SP1 Front-End ISA 2004 Enterprise Edition Array (3-Leg template) We use basic authentication which isn't secure but we compensate with SSL. I'm still torn whether i should turn FBA on. It's just 2 checkboxes. I don't like the cookie aspect, but I like the fact that you authenticate at the firewall and not at the mail servers. ________________________________ From: Robert Lawson [mailto:rlawson@xxxxxxxx] Sent: Fri 4/29/2005 12:12 PM To: [ExchangeList] Subject: Soka|OWA 2003 & authentication Is anyone using OWA 2003 over the web without forms based authentication? If so, which HTTP authentication method are using with OWA? It seems that if you use a FE server (because you have multiple BE servers), then you have to use FBA.
