Hi,
As I understood, you wanted to allow multiple users to access the RDS at the same time. In this case, you should have per-device CALs to be purchased. You need 1 CAL per active connection. Suppose, you need 10 users to be able to connect the RDS at the same time, 10 CALs needed.
Install RDS on the server and add your per-device CALs via the licensing console. You can find many articles to guide you on, how to set up RDS in your server.
Hope this helps.
