 # Lemonldap::NG Handler
-The job support running a Lemonldap::NG handler, but in a very specific configuration only for now. You have to use a MySQL or MariaDB for the config and the sessions, and this DB must be reachable through the Consul service mesh.
-Then you need to enable support for the handler, in your variables.yml file
