I signed up for an azure subscription and a default directory was provisioned for my subscription.
i cannot manage the default directory (e.g. create user or groups) via the azure portal. the portal replies with: "You do not have permission to access these resources."
while i understand that a admin role for an azure subscription is not the same as the admin role to manage an azure active directory; i am unable to find any MS guidance on how to assign the AD global admin role to my azure admin/subscription identity.
