Enabling Integrated Windows Authentication in Firefox
Follow these steps to enable Firefox users to use Integrated Windows Authentication (IWA) to authenticate through ADFS.
Note: The Extended Protection authentication setting on Windows is used to configure Kerberos mutual
authentication. In this type of authentication, to prevent a
man-in-the-middleattack, the server authenticates to the client and the client authenticates the server. Windows 7 on Firefox doesn't support Extended Protection. If users use this client configuration disable Extended Protection in ADFS.
Procedure
