Hello, Last time i tested a coexistence scenario i had to make sure that FBA was enabled on the 2003 Front-End Servers so users wont have to authenticate twice to go to OWA.
Now i am reading TMG publishing for Exchange 2010 white paper and they are advising to enable FBA on the TMG listener for all published Exchange 2010 services (Active Sync, Autodiscover, OWA, OA) and 2003 Legacy access too. This means i would have to set Basic Authentication for all CAS servers. So how do i do for Legacy users if the Front-End Server is set to Basic Auth and not FBA that means that my 2003 users will have to authenticate twice... --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
