Web site on IIS7 asking for windows authentication only when using firefox and not explorer?

Question

Hi, I have a web site on IIS7 and it asks for windows authentication when I try to access it with firefox but it works fine if I use Explorer. With explorer it uses the normal form authentication... how is this possible?

Answer 1

Firefox does not have NTLM enabled by default, meaning FF will not pass along your NT identity to the website. This is enable by defaunt in IE.

You can enable it for selected sites by going to "about:config" and by editing the network.automatic-ntlm-auth.trusted-uris preference.
