Case Study: Transports Metropolitans de Barcelona achieves automated AD management and improved security with One Identity Active Roles

TMB improves AD management and security

Transports Metropolitans de Barcelona (TMB), the main public transport operator in Barcelona, needed an easy-to-use, comprehensive Active Directory management solution to automate routine tasks, enable granular delegation of administrative authority, and provide individual accountability through auditing. AD administrators were spending excessive time on low-value tasks and many users had overly broad domain administrator rights, so TMB chose Active Roles from One Identity to address these challenges.

One Identity implemented Active Roles (alongside MessageStats and Reporter) to automate account creation and daily AD management, enforce role-based security, and deliver built‑in auditing and reporting. As a result, administrators now spend far fewer hours on routine tasks—boosting IT productivity—while granular delegation and audit-ready reports have reduced privilege-related risk and improved accountability and error reduction across TMB’s AD environment.
