We let some consultants share accounts for VPN, and sometimes people crash and their session remains open. It used to be no problem, you'd just get the screen on your next login explaining that you already had a session open and could optionally close the other one upon creating the new session. This still works, but only when I connect to the SA on the inside interface. On the external interface the page doesn't load completely so users aren't able to do anything. Screenshot attached. Any ideas/suggestions would be greatly appreciated.
So far I've had reports from users on IE7,8,9, Firefox, with both Windows XP and 7 OS. I got around this for one realm by setting it to not notify the user of multiple sessions unless they were at the limit, but we have some realms that we really don't want to allow multiple sessions so we're still having trouble with those.
