Hi,
Our Enterprise Portal is only accessible via smart card readers, but I have never attempted using our Enterprise with Field Maps. We use Juniper Systems devices which offer smart card readers, but we have only ever used the systems with our AGOL, and we do not currently have any devices with smart card readers. If we were looking at getting these smart card readers to connect to the Enterprise Portal via Field Maps, would you not be able to work offline? Are you required to be connected through the network on a secure Wi-Fi connection?
