CAL users - 1 or many?

If you have an application that uses a single SQL logon to access the databa
se, but that application is used by many people to access the database, do w
e require one CAL (for the app) or many (for each user)?For server/CAL licensing the licence agreement requires that you purchase a
licence for each user or device using the server. A user is an actual
person, not a login. That's my understanding.
From the licensing FAQ:
"A user CAL allows a particular user to gain access to licensed server
software from any number of devices."
