Are there any examples for having 2 authentication methods run at once? Does this mean the user would have to pick an option when connecting to the server? I don;t think that will work for iPads, xboxes, DVD players, etc accessing a proxy server as they connect automatically without interaction. My current version is 2.6 - will this work with that?
