Hi,
I am using Azure ACS, and configuring ADFS on Windows Server 2012 R2 as an identity provider. When I try to access my application, and then select the ADFS provider, I am able to login seamlessly with Chrome and Firefox (Forms Authentication). However, when I try to use Internet Explorer, I am always presented with the login credentials popup dialogue. Any ideas why this is occurring? I have the "Authentication Policies" set to Intranet: Windows Authentication, and Extranet: Forms Authentication.
I have no idea why the Integrated Windows Auth isn't working.
On the actual ADFS machine, I am able to get this to work by adding the address to the Local Intranet sites. I tried to do the same on another box (on the same domain), however this does not work.
Any ideas on how to diagnose this?
