I upgraded my dfl-210 to the 2.26.00.06-12653 firmware and the User Authentication tab doesn't show up any more for IP4Groups. It still displays for IP4Addresses though. In the list view I can still see User Authentication settings I had previously set for IP4Groups but there is no way to change the settings through the WebUI. Is there a reason it was taken out? I can make changes through the command line interface but it's not as convenient.
