I've been reading a bit about gluu. It uses an ldap or a couchbase backend. I need some of the user data (at least the immutable user identifier) to be replicated to an RDBMS (let's say postgresql).
Is it possible? Also, am I out to lunch trying to achieve this? Cas and keycloak offer the option to hook the product to an rdbms, so I would say no - but it might be an anti-pattern.
Thanks
