The proxy collects manufacturer, models, serial numbers, and bios dates from your CM database. This information is sent to our Recast API. Our API then normalizes the data received and sends it over to manufacture APIs. The information returned to our API is then normalized again, and sent back to your RMS server.
The service account will need read only analyst in ConfigMgr and datareader access to your ConfigMgr SQL database server.
If your Recast Management Server is installed on a server other than your ConfigMgr SQL DB, the proxy account will need to be added to the "SMS_SiteSystemToSiteServerConnection_MP_(YourSiteCode)" local group on that server. This will allow it to read/write to your "inboxes\auth\ddm.box" which is required to gather warranty data.
