Need some help on artifactory.lic

[ningweiii]

Hi friends,
I am trying to build my own artifactory module to apply on my existing running artifactory.
Thanks for the hint of re-encrypted db.properties password, I managed to overcome keep restarting issue.
Currently, I am so close to the end. One thing I have not understood is:

artifactory/manifests/config.pp

Line 273 in 907ad67

if ($::artifactory::license_key) {

1. Do we really need artifactory.lic? It does not exist in my artifactory folder but instead I have artifactory.cluster.license
2. Everytime artifactory restarts, the new created artifactory.lic disappears. And the next puppet run detects the missing file, it will create and restart artifactory again. I am having a very hard time finding out what is exactly the usage for this file. I commented out the block to ensure this license file, my artifactory is still happy.
3. I am using Artifactory Version 6.11.1 Enterprise and in HA

Any help would be much appreciated !
