Why edge doesn't support Single sign-on if website is hosted on localhost?! RRS feed

  • Question

  • The website is configured to use Integrated Windows Authentication and hosted locally on IIS\localhost.
    When I try to access this website the windows authentication pop-up appears.
    Moreover no chance to remember my credentials. If I restart Edge and open this website than authentication form appears again.
    At IE and Chrome the user is automatically authenticated without any windows authentication form, no issue. 

    In addition to that I played with "Internet Options\Local Intranet" and "Internet Options\Trusted sites" and "Logon options" ("Automatically logon only on Intranet zone", "Automatically logon with current user name and password". Nothing helped.

    Any ideas how to suppress this annoying authentication dialog?

  • Hi,

    localhost has no DNS record. Like facebook connect you have to test your production site with a registered internet domain and site certificate.
