Ok, we're having an issue with one of our iPads and I believe it has to do with the network authentication server and a stored password (or somewhere in-between). We haven't had issues in the past with this iPad, but now all of a sudden we are. When you unlock the iPad, connect to the wireless network of our business, and then open safari, you're either taken to our homepage or to a page displaying a "blocked page" websense error. The app should be asking for authentication (much like joining a public network), but it's not. We can get the authentication credentials box to pop every once in a while, but still can't access 99.9% of the internet. This user's credentials are set in websense to be able to visit almost any webpage. Is there a stored file somewhere in the keychain or something that is not releasing it's login information? It's almost like the iPad has credentials logged for accessing the wifi network and a different set of credentials logged for the websense filter. This is very strange. Also, we just used this iPad at a hotel and were able to securely connect to our network with the VPN in iOS, however, we were not able to use safari... it just kept loading the page indefinitely. Any ideas or suggestions are greatly welcomed and much appreciated. Thank you!
