This should work:

Identity returns an IPrincipal

Answer 3

You can read the Name from WindowsIdentity:

var user = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
return Ok(user);

Answer 4

I think because of the below code you are not getting new credential

string fullName = Request.ServerVariables["LOGON_USER"];

You can try custom login page.

Answer 5

Username you get like this:

var userName = HttpContext.Current.Request.LogonUserIdentity?.Name;

Answer 6

You can get the user's WindowsIdentity object under Windows Authentication by:

WindowsIdentity identity = HttpContext.Current.Request.LogonUserIdentity;

and then you can get the information about the user like identity.Name.

Please note you need to have HttpContext for these code.
