EJB3 later ?). | | And also avoid a heavy drawback : in High Availability, having a replication of data from LDAP to a DB is not a nice thing, if the purpose is just "caching with hibernate". | One more DB in HA is a lot of prod work, and a weak part more. | | I guess this is new and will evolved when it is time. | I can customize a users and roles module too. | I wish I can and contribute with it. | but I don't see any opportunity (and time) to do that before... a long time. | As a follow up to your post on the JIRA task, this strategy would be hidden as an implementation details of the Identity Modules (UserModule, RoleModule etc), as I stated earlier in my post on the JIRA task. The HSQL based optimization/caching will apply only to the core DB based IdentityModule implementations that we ship out-of-the-box with the Portal. For other Identity Modules it will fall back to retrieving Identity Data via Identity interfaces and any performance related optimizations in that case will be delegated to the actual implementation and not to the CMS Security engine.
