Abstract: A method and system for providing flexibility to a license management system. A license management system permits the concurrent use of n copies of a software program over a network comprising a plurality of client workstations, each client workstation having a copy of the software program installed thereon requiring an authorization from one of a plurality of S license servers each time the software program is used. For security reasons, the license management system requires that at least the integer majority of the plurality of license servers is active at any time. The method and system allow to change the number of license servers, but impose the following limit: taken s1 and s2 respectively as the minimum and the maximum number of servers that may belong to the cluster, the sum of the integer majority of s1 and of the integer majority of s2 must be strictly greater than s2.
