Tectia Server will attempt to restore persistent network connections of the user logged on the same way also when it starts the SFTP subsystem (sft-server-g3). In addition to this, it will also attempt to restore connections to virtual folders that reside on network shares. However, at this point the client program communicates with the server using SFTP protocol. This protocol does not include any support for challenge response authentication because it is designed to be used over a connection that has already been authenticated. In this case the success of Windows network connection attempt depends solely on the credentials provided during the initial authentication to SSH server. Therefore, the only reliable alternative in this case is to use password authentication that uses credentials of the native Windows account.
