Database Connectors is a separately licensed product, distinct from the activation information you received for your development product. You are required to activate a separate license for each type of database you intend to connect to.
You may request a license file for one or more users. The number of users (user limit) is set in your license agreement with Micro Focus. When you receive your products, the package includes codes and keys for every product you ordered; enter these code/key pairs using the Activator utility, which creates the required license files and places them in the required location.
