To work with Vault, you need to enable TLS on the Artifactory application. Details on how to do this are described here, an outline of the necessary steps can be found below:
A] Enable TLS for Access by adding the TLS setting:
#If the file does not exist, that is ok vim $ART_HOME/etc/access/access.config.lastest.yml
B] Add the following lines:
security: tls: true
C] Change the file name:
cp access.config.latest.yml access.config.import.yml
D] Reboot Artifactory for the change to take effect:
service artifactory restart
