I want to implement Windows Authentication into ABP.io framework project. I want to get Windows user and login that user, if user is added into ABP.io database.

I’m using version 6.0.3 with .NET Core, MS SQL Server and Angular UI.

I’m using Authorization Code Flow, so I’ve overriden login page and created CustomLoginModel that extends LoginModel. In that model I’ve implemented Windows login like this:

var windowsUser = WindowsIdentity.GetCurrent().Name;

if (windowsUser.Contains('\'))
{
    windowsUser = windowsUser.Split('\')[1];
}

await IdentityOptions.SetAsync();

var user = await UserManager.FindByNameAsync(windowsUser);

if (user == null)
{
    Alerts.Danger($"User {windowsUser} not found!");
    return Page();
}

if (await UserManager.IsLockedOutAsync(user))
{
    Alerts.Warning(L["UserLockedOutMessage"]);
    return Page();
}

await SignInManager.SignInAsync(user, LoginInput.RememberMe);

await IdentitySecurityLogManager.SaveAsync(new IdentitySecurityLogContext()
{
    Identity = IdentitySecurityLogIdentityConsts.Identity,
    Action = "Succeeded",
    UserName = user.UserName
});

return RedirectSafely(ReturnUrl, ReturnUrlHash);

I’m facing issue that it works when I’m running it locally and stops working when I deploy it on IIS. On IIS I’m getting user from application pool. Is there any other way to get Windows user?
