Google Maps Editor Permission to Add Maps

I have Google Maps (ver. 2.5) on WordPress 3.3 multisite. I can add maps as a network admin, but I have users set up in editor role that cannot. They can see the list of existing maps and insert an existing map into a blog post. However, they cannot add any new ones. Is the add new maps function restricted by permission level? If so, what php file can I find that setting to adjust it. Thanks in advance.
