This is already possible, you can set up to 10 different user profiles with GLD. go to setup – Config tab – user profiles:
Here you can activate/deactivate the profiles, change each users permissions and set passwords for the users.

You could setup a user profile with only the controls you wish users to have and give them a set password to use. Then set your own password for the admin account so they are locked out from accessing everything.

I figured it out. I wasn’t turning on the users.
