Admin page security and google checkout

[opnsrc]

I'm trying to find the best solution to add security to the admin interface that will still allow google checkout to communicate with OSCommerce without giving errors. I found the 'Secure Admin Login-Logout': http://www.oscommerce.com/community/contri...ch,admin+secure contribution, but it's giving me errors stating that the 'table oscommerce.administrator doesn't exist' in the mysql database. I'm not sure if this is the best solution or not. Does anyone have any success stories implementing security for the admin page and still allowing for full functionality with google checkout?
