I was setting up a MacMini running Leopard for a client and I was tweaking some of the options and controls for “Remote Management”. I had connected in with Remote Desktop Admin with an admin level account and wanted to tighten up some of the controls for who was authorized to connect. Using this screen here:
I clicked on the “Only these users” button, without having put the account I was connected as into the list, and got dropped from the connection. Be warned that all of these controls take IMMEDIATE effect. Thanks Apple.
