CyberArk does not implement license limits by controlling the number and types of users that can be provisioned in the vault. CyberArk implements license limits by controlling the number and types of users that can authenticate to the vault and use its features. The license limits are based on the user types and objects that are defined in the vault, such as Vault Users, LDAP Users, LDAP Groups, Safes, Accounts, etc. The license limits are enforced by the License Manager, which is a service that runs on the Vault server and monitors the license usage. The License Manager can send notifications and alerts when the license usage reaches certain thresholds, and can also block or allow access to the vault based on the license status1.
