I am trying to allow people in support to provision new customer portal users (We haven't switched to communities yet). When I go to the contact record I see the 'Manage External User' button, but other users cannot see this.

I have tried the 'Manage External Users' and the 'edit self service users' permissions, as the above link suggests, but this still doesn't make the button appear. What do I need to do (preferably in a permission set) to allow other internal users to manage external users for the customer portal?
