Depending on what you mean by "loggin in via VPN". Do you mean "connecting to the VPN server", or "logging into some service that is available on the network that they are communicating with via a VPN", or something else? Documentation [1] for the management interface's "echo" command says "Essentially the echo command allowed us to pass parameters from the OpenVPN server to the OpenVPN client, and then to the management client (such as a GUI)." Of course it requires the GUI (such as Tunnelblick) to do something with the "parameters". As far as I know, Tunnelblick doesn't currently do anything with these "parameters", but I'm open to extending Tunnelblick to do "something" with them. The documentation uses as an example a message of "forget-passwords" and Tunnelblick doesn't do anything with that (it could forget any passwords it has saved for the configuration, I suppose). It isn't clear to me exactly what the client does when it receives the "forget-passwords" command pushed from the server: does the client itself forget saved (in memory) passwords? Does it also send that through the management interface? I can imagine a "display-to-user" command with a UTF-8 string parameter which Tunnelblick could interpret by displaying a non-modal window with the message, but there are lots of other options (Tunnelblick could use the macOS "Notifications" instead of popping up a window, or it could allow for a title for the window, or it could allow HTML (with JavaScript?!!!) or, I suppose, anything. Does the Windows GUI do anything with these "echo" parameters?
