Internet Explorer prevents domain user authentication in LightSwitch app

Question

In the LightSwitch Access Control tab I have Use Windows authentication and Allow any authenticated Windows user selected. Authentication works fine in Firefox/Chrome but fails in Internet Explorer. I suspect it's because Internet Explorer prepends the username with DOMAIN. If I do the same thing in Firefox/Chrome, it won't authenticate. Is there some way to enable DOMAIN\username instead of simply username? Maybe in the web.config? Thanks!

Answer 1

I disabled Enable Kernel-mode authentication under IIS Manager » Server » Sites » Default Web Site » MyWebsite » Authentication » Windows Authentication » Advanced, and now IE logs into my LightSwitch app automatically. I suspect this changes the preferred authentication order from (1. Negotiable 2. NTLM) to (1. NTLM).
