Magento enterprise has some amazing features out of the box that allow you to restrict roles to specific web sites and sections. Unfortinately the system out of the box doesn’t let you micro manage the configuration fields. Imagine that you have a senario where you want an admin user to be able to edit certain configuration fields, but not all of them. Out of the box magento lets you limit the roles to certain sections like “Store Email Addresses” or “Contacts” but it doesn’t let you limit each individual item.
For example, I want an admin group to be able to go into the backend and edit the “Store E-mail Addresses” but I don’t want them to be able to edit anything but the fields “Custom E-mail 1″ and “Custom Email 2″. Well I have down and dirty way to limit fields from your admin users. Follow my steps and you will be able to limit the system configuration on your admin web site past the out of the box norm. This tutorial requires you to know a bit about css and php.
