-- This is aaa.lua - AAA filter with portal validation.
-- It checks that an oauth validated account was logged in through a specific
-- OAuth provider, and if used, allows access to private lists.
-- To use this as your AAA lib, replace aaa.lua in site/api/lib with this file.

local config = require 'lib/config'

-- Allow anyone logged in through Google+ access to private emails
-- This is a direct string match, not a GLOB
local valid_portal = "www.googleapis.com"  
local grant_access_to = "*" -- use * for access to all, or specify a (sub)domain to grant access to

-- Get rights (full or no access)
local function getRights(r, usr)
    local email = usr.credentials.email or "|||"
    local xemail = email:match("([-a-zA-Z0-9._@]+)") -- whitelist characters
    local rights = {}
    
    -- bad char in email?
    if not email or xemail ~= email then
        return rights
    end
    
    -- Check if admin or if the right oauth portal was used
    if usr.internal.admin or oauth_domain == valid_portal then
        table.insert(rights, grant_access_to)
