Cisco VPN on iPad - remember password setting

I've tried to configure some iPad's to connect to Cisco VPN by hand and via IPCU. It appears that the user's password for VPN is saved when initially entered (both by hand and by IPCU), but upon connection to the concentrator, the user is prompted for the password and then the field is changed to "Ask Every Time". Even if you go back and enter a password here and save, it will go back to "Ask Every Time". I've changed our Cisco concentrators to allow the users to save passwords for this particular VPN group, but that didn't fix the problem either. To me, it appears a bug, but wondering if others had seen this or not.
