Case Study: Los Angeles Department of Water and Power achieves single‑ID access and 95% performance improvement with Oracle Unified Directory (Oracle)

LADWP Simplifies Access to Online City Services by Consolidating Directory Infrastructure

The Los Angeles Department of Water and Power (LADWP), the nation’s largest municipal water and power utility serving nearly 4 million residents, needed to simplify citizen access to services across LADWP.com, MyLA311 and LACitySan. The agency faced fragmented identity repositories, infrastructure complexity, the need for a one‑tier LDAP directory with embedded storage, and real‑time replication between two data centers to ensure availability and reduce administrative overhead.

LADWP consolidated directory services using Oracle Unified Directory and Oracle Identity Management, with implementation support from AST Corporation, creating a single secure user ID and a one‑tier solution managed by one administrator. Multi‑master replication removed single points of failure and simplified infrastructure, while performance improved dramatically—search response improved by 350% and overall system performance by 95%—delivering high availability, lower costs, and a scalable platform for future growth.
