All indications point to us having Enterprise Plus , including the big "Backup Enterprise Manager Enterprise Plus Edition" banner.
We are testing the 9.5 RTM and can't access the /api/cloud branch of the API. It returns a 403.
POSTing to http://xxx:9399/api/sessionMngr/?v=v1_3
doesn't list /api/cloud in the links, either.
All other branches seem to function properly.
