Microsoft OneDrive configuration

If you don't have the ui section for onedrive then the toggle to use it as a backend will not show in the interface.

"ui": {
    ...
    "services": {
         "onedrive": {
              "clientId": "{microsoft client id}",
              "tenantId": "{tenant id}",
              "redirectUri": "http://localhost:9000/onedrive-callback"
          },
          ...
    }
}

After you've setup onedrive as per the notes copy the values for clientId and tenantId into the configuration. The value for redirectUri should be set to the hostname of your deployment (the value shown is for the development setup).
