How many licenses?

Question / Problem

How many licenses do I need?

Answer / Solution

The number of licenses will be calculated per user. An user cannot share his license with other users. That is technically secured. As soon as the user logs in via the login mask, he consumes a license.
The Software only needs a single installation on a single machine (server). For this installation, you need a single license-key. This license key contains the valid number of licenses/clients.
