So ... can anyone comment on the assertions in there that LDAP replication is easier/better than RDBMS replication?<p>The data backend is not my area of expertise but in working with a competitor stack with an LDAP datastore lately the fact that the backend store was not a database, does not seem to be that performant and is not really transactional has been a pain point. Effectively having to mimic relational structures using embedded JSON in sub-attributes seems like a terrible way to carry on - I have no idea if Gluu makes you work this way, but again, the competitor seemed to.
