The License Server
The License Server is the computer where your administrator installs SDL Licensing Server Manager. The computer is hosted on the customer site and should be located in the same LAN where the client applications are installed.
Network licenses can be activated using SDL Licensing Server Manager. Then, any other computer which requires licensing (client) can connect to the server and request a license when concurrent licensing is used. SDL Licensing Server Manager can host both SDL Passolo and SDL Trados Studio commuter licenses.
