6.3.2.5 If you want to return the Roamed License early

If your plans change and you would like to return the license before the roaming time has expired, reconnect the system to the network (so that it can contact the original license server), and set the environment variable RLM_ROAM to -1. Now run the program and let it check out the license. Once the program exits (or does a checkin), the roamed license will be returned to the license pool on the server. Please note that if you change the server node name or port number after you roam the license, you will not be able to return the license early.
