You can install the client software as a managed client or as an unmanaged client. In most cases, you should install a managed client. You may want to install an unmanaged client if you want the user to have more control over the computer, such as a test computer. Make sure that the unmanaged client users have the appropriate level of knowledge to configure any security settings that are different from the default settings.
You can convert an unmanaged client to a managed client at a later time by replacing the client-server communications file on the client computer.
