The user licensing is also based on connections. The ExtraWeb Server and the ExtraNet Server both read the same license file. Each of the two servers, as well as the Management Server, has its own section in the license file that is read at startup. The license file primarily controls cryptographic strength and the maximum number of users and connections.
Today there are two types of capacity-oriented licenses.
The grace value is defined as a percentage of maximum allowed connections. Typically, grace has been set to 150 percent by default. Under normal operating situations, this allows a maximum capacity of 1.5 times the true license limit before the AEC will begin ignoring new connection attempts. Once connections reach 100 percent, warnings are generated in the system log files to notify the administrator that the license is being exceeded. In this licensing model, the server capacity is controlled, not by total connections running through the system, but by uniquely authenticated users running through the system with a per user connection maximum.
