SOTI HUB - ERG?
1.Would we need to deploy ERG?
Only if your SharePoint server is behind a Firewall that restricts access to devices outside of your network. If SharePoint is reachable outside of your network then ERG is not necessary.
2.Can it be installed on the same server as mobicontrol?
Not recommended, it uses the same ports as the DSE and the Management Service. It is best practice to put this on a separate box.
3. Webdav - Can this be installed on the same server? and do we need ERG for this?
You can configure whatever port you want in your WebDav web service to avoid conflicts, so it is possible. I would recommend against installing additional services on your MobiControl servers however. ERG is only necessary if the WebDav server is not reachable outside of your network.
Thanks alot, regarding ERG can this be set to authenticate the devices against SOTI, so that no ldap integration is needed?
ERG uses Port 443 to check against Management Server whether a device is registered or not. Access is only granted, if it is enrolled correctly.
