Firefox with Windows Authentication problems

Product: PowerShell Universal
Version: 3.1.4

I can’t seem to get Firefox (and mobile for that matter) to get authorization when using Windows Authentication. I’m not sure if I’m missing something here, but it’s expected for that to work isn’t it? There weren’t any notes in the documentation that I could see for that.

I have a role binding (Administrator) to a claim for a security group in AD. If I login with form authentication to the dashboard using the built-in Admin, it works normally. If I trace the authentication process, it starts the whole thing and then ends at if I go to If I go to it just throws two 401’s and doesn’t let me past.

Not sure where to go from here. I don’t know if it’s a configuration issue on my end or if it’s an issue with authentication.

I have a service account setup for the Windows Service, I have https enabled, and I am pointing to an SQL server that the service account and my user account has full access to. I did disable every other built-in role except for the user role, but I set my identity to Administrator manually, just in case that was a cause for problems. If there are some other logs I need to provide, I’d be happy to.

I realize now that I am an idiot sandwich.

Windows Authentication just doesn’t work in Firefox because of The ‘Windows’ part in there. I did find a ‘workaround’ here: Configuring Firefox for Integrated Windows Authentication (

I ultimately ended up getting WS-Federation working in my environment and that’s a cleaner solution for my needs.
