Is it possible, safe and practical to use Windows Integrated Security on an Extranet?
E.g. there is an IIS website on the intranet that can be used over the LAN with integrated authentication. When the user disconnects from the LAN he wants to be able to use the browser on his domain-joined-notebook to connect to the same website over the internet (no VPN) without having to logon separately.
Yes, it is definitely possible to use integrated security. But, it also depends on the framework you are using for authentication. In ASP.NET you can use built in authentication module. You to set the authentication mode to "Windows" and .Net will manage it for you. You can also have different roles for managing different types of users in your web app. You web app must be available outside your LAN(i.e. your firewall should not block incoming HTTP requests)
