CAL Per user: how assign to users

Hello,

I'm setting up on my physical server RDS. My server is windows server 2012 foundation.

As you see in image below, I Installed RD Licensing Manager

I linked it with my 5 CAL per user (image 2)

but I have no RD Connection broker(Is it optional?)

As you see in last image I activated server

Now, How can I provide access to my 5 users? How have I to go on?

Thanks

Carlo
