Well, not so simple actually. To start, go to QEMC --> System --> Licenses --> QlikView Server --> Client Access Licenses (CALs). You will see an overview of your licenses. In the Assigned CALs tab, you will be able to see only Named User CALs. If you have Document CALs, you can see that from the User Documents tab. Which leaves Session and Usage CALs. Unfortunately I don't know of a way to differentiate which one is assigned to which user. However, it might be helpful to note that QVS will assign first session CALs and only when those run out will it resort to Usage CALs. Once you see which users have Named User CALs, you can go to Status --> QVS Statistics and see what users have sessions open--by comparing this against the Named User list, you will be able to see which ones have Session/Usage CALs assigned. It's kind of a hassle, but I don't know of any easier way.
