I use a smartcard to connect to my TFS via Visual Studio 2012. VS does it well: asks for the smartcard's PIN then establishes a connection. Unfortunately I can't reach the same result via WebStorm. It tells "Forbidden". idea_output.txt contains several responses from the server which begin with:
HTTP/1.1 403 Forbidden ( The page requires a client certificate as part of the authentication process. If you are using a smart card, you will need to insert your smart card to select an appropriate certificate. Otherwise, contact your server administrator. )
It's really awkward to switch to VS each time just to check-out some files.
