How do I configure a customer in ServiceDesk without a login? I need to be able to assign customers to incidents (and have contact details associated with that) but I don't want to assign logins. My service desk operates without customer portal access, only via telephone and email requests (which would be processed manually). It appears as though the only way to have customers in Jira Service Desk is if they have accounts, which I don't want because customers will never login.
