Thanks for answering, with your help I've been able to pinpoint the exact cause of my issues with Liferay. BUT copying the keys prior to start CAS is not working, you see, I'm developing using Docker containers, and before starting the image I copy a lot of files, including the keys, and I've found these messages in CAS log (most relevant in yellow). The main reason is that the testing environment is a Docker container. It's CAS 6.6.

Confirmed when inspecting the files in the container. And the prior idp-metadata imported by Liferay is not valid anymore. Until re-imported. Is there a property to override this behaviour? So far, the workaround is re-creating the idp-metadata using CAS endpoint "/idp/metadata", and re-importing it in Liferay, it takes no longer than 2 minutes, but the client is worried that in the production environment, where is known that docker container restart with no reason, this can be troublesome.
