Step 3 of 4712 (security review F14). The Customer role has change rights on
service requests and nothing checked whose they were. For customer contacts:
another customer's request is not found (read, update, delete); creating or
moving a request to a customer the contact does not own is refused (403); a
contact's request is always requested by that contact. unit/customerunit adds
units only to the contact's own customer (or one of its head office's).
Checked: another customer's request 404 (was 200), create for another customer
403, own request created and deleted.
