Abstract: As enterprises adopt hybrid IT environments, traditional network perimeter defenses are no longer sufficient to protect critical resources. Identity has emerged as the new perimeter, with LDAP and Active Directory (AD) serving as foundational technologies for managing authentication, authorization, and access control across distributed systems. This review examines best practices for LDAP and AD management, including role-based access control, multi-factor authentication, automated provisioning and deprovisioning, monitoring, and incident response. It also explores integration strategies with cloud platforms, Single Sign-On (SSO), and DevOps workflows, highlighting real-world implementations and lessons learned from finance, healthcare, and government sectors. Finally, the article addresses emerging trends such as Zero Trust architecture, AI-driven behavioral analytics, and multi-cloud orchestration, emphasizing the evolving role of identity in securing hybrid IT infrastructures and ensuring compliance, operational efficiency, and resilience.
