Displaying built in Modules to customer-self-service

I've trying to display a built-in module (like contacts, accounts, etc..) to the customer support portal. I'm not sure if I should treat it like a custom module (not really any functionality to it).

What I have tried:

Editing the self-service role updating the permissions for the role that is assigned to our Portal users. In Admin > Role Management -> Customer Self Service Portal role. and setting the following permission to display the module:

  • Access - Enabled
  • Access Type - Normal
  • List - All
  • View - All

And after that, when i go to the Admin > Sugar Portal > Configure Portal. There are no hidden modules for me to put in the Displayed Modules list...

Expected output:

Displaying the account module with the contacts corresponding to the account so the customer can see/edit his/her account and contact info.

Should I edit the vardef file to make a module visible in the sugar customer portal?
