I just confirmed that the IPAD will not connect to a Cisco ASA when the group name contains a dash ( - ) such as IPAD-2. Change this to IPAD and it works fine.
It will error out with "The VPN Secret is incorrect." even though the password is fine. The problem is the Group Name with the dash in it.
I confirmed this on my Cisco 5505 ASA with firmware 8.2.(1)
