Argh, so Apple devices connected to our campus wifi via Aruba mobility controller are no longer being redirected to a captive portal. They just sit and time out when launching Safari. My suspicions are with the recent release of Apple's OS X 10.8.3 update.
It used to work previously with the "walled garden" feature we have set up, which basically permits http/https access to *.apple.com in our captive portal role.
Not sure which address I need to be whitelisting now... has anyone else had any luck?
Thanks in advance.
