Under iOS 5, one could disable the Auto-Login feature (the panel that slides up from the bottom of the display when connecting to a Wi-Fi network that requires you to log-in, like Starbucks) on a per-network basis (the Auto-Join toggle is still there). My university requires users of its wifi network to login, but the way in which the auto-login feature determines if the network requires one to be logged in does not work, and instead presents an "access denied" message in the pane, giving me no option to enter my credentials. I am nearly-certain that being able to disable auto-login would resolve it. Has the option been moved? The issue occurs on both my iPhone 4 and iPad, and I can't find a way to disable it on either.
