The benefits of having compact entries in the database are available today with Sun Directory Server Enterprise Edition 7 and Sun OpenDS Standard Edition 2.2, writes Ludovic Poitou in his blog "Sun Directory Compresses Data for Better Performance," adding that both solutions are helping customers to reduce the overall cost of ownership of the directory services.

Sun OpenDS Standard Edition (SE) 2.2 provides improvement to the core directory server as well as a new proxy server capability to manage requests between LDAP client applications and remote LDAP servers (either Sun OpenDS SE 2.2 or Sun Directory Server Enterprise Edition (DSEE) 7.0). It also includes a web-based "Namefinder" lookup sample application to browse users in the Directory.

Sun announced the availability of a new, fine-grained entitlement enforcement engine as part of OpenSSO Express 9, and a next-generation directory proxy server as part of Sun OpenDS Standard Edition 2.2. The entitlement enforcement engine supports enterprise deployments and provides mass-scale extranet deployments with a complete off-the-shelf, standards-based solution that can externalize authorization for more than 100 million users. The new directory proxy server proactively maintains up-time as activity increases with a "global index" to help easily distribute and balance loads - based on factors such as any identity attribute or based on a traffic distribution algorithms.
