Microsoft.AspNetCore.Server.IISIntegration If true the middleware should set HttpContext.User. If false the middleware will only provide an identity when explicitly requested by the AuthenticationScheme. Note Windows Authentication must also be enabled in IIS for this to work. Sets the display name shown to users on login pages. The default is null. Used to indicate if the authentication handler should be registered. This is only done if ANCM indicates IIS has a non-anonymous authentication enabled, or for back compat with ANCMs that did not provide this information. Populates the ITLSConnectionFeature if the MS-ASPNETCORE-CLIENTCERT request header is present. Configures the port and base path the server should listen on when running behind AspNetCoreModule. The app will also be configured to capture startup errors.
