In previous licensing implementations, users were granted access to network services on a server basis. This meant users consumed a license on each server to that they logged in to.This is known as the Server Connection License model.
In NetWare 6, the User Access Model grants users access to the network, allowing them access to all network services that they have rights to. This means a user obtains only one license regardless of the number of servers he logs in to.
Within the Server Connection model (SCL), you purchased licenses for the total concurrent users on each NetWare server. With the User Access Licensing model, you purchase licenses for the total number of User objects that will login to the network. When a User object logs in to the network, it obtains a license unit. That license unit is reserved for that user. If the user does not log in for more than 90 days, then the license is automatically released and made available to the next user that needs it.
Since managing the network usage is now a network administrator's priority, Novell has released a new NetWare Usage tool that lets you see a statistic of the total number of licenses consumed and generate a report of users' last network access. See Using the NetWare Usage Tool for more information.
In the User Access Model, non-User objects like printers and ZENworksTM do not consume user licenses.
