To restrict a specific Reseller user from having access to the "Feature Manager" in their WHM, you will have to ensure the following is configured:
- The Reseller is owned by root
- The Reseller does not have access to the "Packages" ACL
Since the "Feature Manager" functionality in a Reseller's WHM is tied to the "Packages" ACL, this needs to be removed from the following location:
WHM >> Resellers >> Edit Reseller Nameservers and Privileges
After you select the Reseller user you wish to remove this functionality from, locate the ACL named "Packages" and unselect it.
After doing this, your selected Reseller user will no longer be able to access the "Feature Manager" in their WHM.
Since this ACL also controls the ability to create, remove and edit packages, the Root user will have to create and manage the packages that the Reseller will use and assign to its users.
