SQL Server Client Tools licensing

Hello all, I’ve been trying to find out some licensing info concerning the client tools and SSMS, but can’t find anything concrete. But after some googling I come to know that, if a user or a device has the legal right (also known as the license) to access a SQL-Server than it is legal to install client tools in order to give access to it and manage it.  Of course, but only the users with a valid license will have the right to use these tools. There is no special licensing to take into consideration for installing the client tools other than to have the right to access a SQL-server instance.  e.g if this SQL-Server is operating under the Per Processor mode, everyone and every device in your organization have the right to install the client tools in order to access and manage this SQL-Server.  Of course, this doesn’t give the right to use these tools to access *another* SQL-Server for which a particular user/device wouldn’t have the right to access it in the first place.
