hi
We have exchange 2010 sp3 installed and working. we have two sites
Site a
1 x CAS
2 X MBX
Site b
1 x cas
2x mbx
site A is the primary site we currently publish owa our through our TMG server located in the DMZ this is working as expected and carries out the forms authentication. our internal domain is company.local but our external domain is company.com we have created split DNS so that we could use a wildcard cert and to deal with CA new rules. All URL's in Exchange are configured to use the external reference of company.com/
on the IIS server we have a redirection on the root of the site to redirect the requests through to OWA folder and we have basic Authentication enabled. on the OWA folder we have basic and windows authentication.
The problem we have is that when users try to access OWA internally we get username and password box appears once you login with this it then takes you through to the the normal login screen and you have tyo login again I'm thinking that this is the windows authentication that is causing this but not sure?
also would be good to get an understanding as to what the Authentication, SSL and redirection setting should be set to on your CAS servers as looking at the ECP and autodiscover folder within IIS this currently has a redirect set to go to OWA surely that cannot be right,
thanks
J
