In Qlik Sense there are two alternative license models: the serial and control number and the signed license key. The License Enabler File (LEF) defines the terms of your license and the access types that you can allocate to users.
When licensing Qlik Sense using a serial and control number, the LEF can be downloaded when the serial number and the control number have been entered in the Qlik Management Console (QMC). The LEF can also be pasted directly into the QMC, if, for example, no network connection is available. There are two license types that can be activated using a serial and control number: Professional and Analyzer Users licenses, and Qlik Token licenses.
When licensing Qlik Sense using a signed key, the LEF file is stored in the License Backend.
For a complete overview on licenses, see: Qlik Sense Licenses
Professional and Analyzer Users license
Professional and Analyzer Users licenses grant a predefined number Professional and Analyzer (user-based) access type allocations. The LEF file determines the allocation of the access types.
You use tokens to allocate access passes to users so that they can access Qlik Sense. The License Enabler File (LEF) determines the number of tokens that you can allocate, and holds the number of tokens available for the central node in a site. This means that a Qlik Sense site needs at least one (1) LEF. A user without an access pass cannot access apps.
Increase in tokens
When the number of tokens in the LEF increases (for example, when buying additional tokens), the new tokens are added to the pool of unallocated tokens that can be used to allocate access passes that allow users to access Qlik Sense.
Decrease in tokens
When the number of tokens in the LEF decreases, the following happens:
- Unallocated tokens are removed.
- If step 1 is not enough to meet the decreased number of tokens in the LEF, any tokens that are freed up by removal of access passes cannot be used for new allocations until the number of allocated tokens is below the new number set in the LEF.
