How to manage your DSLS licenses (Allow/Deny/Reserve/Limit..) effectively using License Authorization rules?

When working with Dassault Systemes License Server there are times when just installing and enrolling the license file isn’t enough. For the bigger companies with multiple license for different products it’s important to manage the licenses so that certain group of users is allowed to use certain products or reserve specific number of licenses to a group so that others cannot use it.

For DraftSight we have different packages available like Enterprise, Enterprise Plus. Let’s say there are some users who are working on a project that needs access 3D features from Enterprise Plus package. If these licenses are already occupied by user who can work with Enterprise Package, it can cause unnecessary delays and downtime for the users. To avoid this we can use authorization rules and reserve 3D license for specific set of users so that these licenses will be available when users need them.

Define users or groups to define authorization rules:

  • Launch DSLS License Administration Tool
  • On Server definitions tab check server is connected
  • Go to Authorizations tab, Right click in a blank space under Users\\Host\\IPRanges and select Add.
  • Add Users\\Hosts\\Groups

We can see in above image that  4 users and 2 groups are defined. We will assign the group of users to access the certain licenses only. (You can see users added in certain group by double clicking on it)

NOTE: Usernames are the windows login username and hostnames are system names.

Add authorization rules:

To add the rule, go to Authorizations tab >right click on the license you intend to add a rule to and select Add new rule.


Select Allow/Deny/Reserve/Limit/Composite. We will use Reserve to reserve Enterprise Plus licenses to users (user1, user2) in this group so that other users will not be able to get these 2 Enterprise Plus licenses.


Similarly we can apply different rules to different licenses and manage how the licenses will be used.

We can also export the authorization file as .xml> edit it and reimport it.


For more information about different rules refer to ‘Setting License Authorization Rules’ section in DS License Server Installation Guide.
