Understanding license keys

Depending on whether you have purchased software licenses, your license keys might provide limited evaluation usage of the software for a specific number of days, or permanent access to features for a specific number of computers. If you initially install using an evaluation license key, you must eventually replace that evaluation key with one or more permanent license keys to continue using the software.

Your capacity for enabling access for standard UNIX services or applications is defined by the total of all of the licenses you purchase and install. For example, if you install three valid license keys that each enable 100 workstations for UNIX access, you have a total of 300 workstation login licenses available.

Each license you purchase has a 24-character registration key that specifies:

  • The type of license granted by the key.
  • The total number of computers that may be enabled under this key’s license. If this is an evaluation key, the number of computers is unlimited, but the license count is displayed as zero (0) to indicate no computers are licensed under the evaluation key.
  • The time limit for the key. If the license is a permanent license key, the time limit is not applicable. If the license is an evaluation key, the time is set to a duration that is defined in the license key.

Because each license key specifies a set number of computers, it is common to receive multiple license keys. You can provide these license keys when you install Centrify software on a Windows computer or after installation using the licensing service.
