Sorry, assume they match. "usuario-ikev2" is the real user I'm using,
and I substituted it with "roadwarrior" in my email but obviously
forgot to do so in every instance. The problem is not there.

I don't understand this. As for wildcard or rightid=%any, that is not
viable because the configuration MUST be unique for each user, so it
can assign their fixed IPs...so what might the problem be? Maybe the
roadwarrior is presenting the subjectAltName?
