I am running Web App on my IIS server and I have Windows Authnetication enabled.

On client, when I run PowerShell script: Invoke-WebRequest -Uri {url} -UseDefaultCredentials, its working fine. Also in C# when I use UseDefaultCredentials = true in HttpClient, its working fine.

But when I run bash command: curl --negotiate -u : {url} I am gettin 401 Unauthorized error

Why?
