I think he is just talking about just the username and not the password. Cisco stores the last username used inside each connection profile file. We do not allow password storage via our 3005 but the username is still saved. As far as I am aware there isn't an option to prevent this. At least not one available from the GUI.
Thanks for the clarification. Let us know the outcome of your testing. Also, the previous post by Alfred is correct. This is read only. So, the end user can still access the .pcf file and edit this option.
