Configuring Multiple OWA/ECP Virtual Directories on the Exchange 2013 Client Access Server Role
Hi Greg
Thanks for sharing. I am trying to configure TMG to pre-Auth (FBA) and FBA authentication on internal and external. You mention above in scenario’s 1 we no longer need the multiple OWA website to make it work. and don't have to do anything.
But it is not working for me. the TEST RULE fails if I don't change the OWA Virtual directory to NTLM and BASIC.
by default my Exchange 2013 virtual directory is set to following authentication
ClientAuthCleanupLevel : High
InternalAuthenticationMethods : {Basic, Fba}
BasicAuthentication : True
WindowsAuthentication : False
DigestAuthentication : False
FormsAuthentication : True
LiveIdAuthentication : False
AdfsAuthentication : False
OAuthAuthentication : False
ExternalAuthenticationMethods : {Fba}
is the setting correct for scenario 1 to work?
Can you please provide me more details on how to set the scenario 1? will it work in Exchange 2013 without additional website? Do you know any TechNet article on how to do it?
