Regular users can't select a Category (option is missing)

Regular users can't select a Category (option is missing)

I just took over administration of our ServiceDesk install and recently updated to build 6012. I'm a bit confused by something:

As a technician, I can select any of our pre-defined categories and sub-categories, but if a regular user logs into the system the New Request form only contains the following fields:

Name * Workstation ID

Sub Category
Item
Subject *
Description

Is there an option I need to tweak somewhere to allow a user to select a category for their request, or is there something wrong with our installation?
