Key Responsibilities (Active Directory Admin)

1) On-Prem Active Directory (AD DS) Administration

· Administer AD DS components: forests, domains, trusts, OUs, users/groups, and delegation models.

· Manage and maintain Domain Controllers, ensuring health, capacity, patching, and lifecycle compliance.

· Configure and maintain Group Policy Objects (GPOs) including security baselines, hardening, and troubleshooting.

· Monitor and troubleshoot AD replication, SYSVOL issues, DFSR/FRS (as relevant), and domain controller health.

· Manage AD-integrated DNS including zones, records, scavenging, forwarders, and resiliency architecture.

· Perform AD upgrades/migrations (domain/forest functional levels, DC replacement, OS upgrades) with minimal downtime.

· Support Active Directory Certificate Services (AD CS) operations such as CRL publishing/renewals (if in scope).

2) Azure AD / Microsoft Entra ID (Cloud Identity)

· Administer Azure AD / Entra ID tenant configuration and identity services for enterprise users and applications.

· Implement and manage Conditional Access, MFA, Identity Protection, and risk-based access controls.

· Manage Privileged Identity Management (PIM) and privileged access policies (JIT/JEA, role assignment governance).

· Configure and support SSO, Enterprise Applications, App registrations, OAuth permissions, and federation settings.

· Operate and optimize hybrid identity services (cloud-only and synced identities) aligned to security standards.

3) Hybrid Identity & Synchronization (Azure AD Connect / Cloud Sync)

· Deploy and maintain Azure AD Connect / Cloud Sync for identity synchronization and writeback (where applicable).

· Manage synchronization rules, troubleshooting (staging mode, metaverse, connector space), and sync monitoring.

· Support hybrid authentication models: Password Hash Sync, Pass-through Authentication, or Federation (AD FS).

· Manage hybrid features like Seamless SSO, device writeback, group writeback, and lifecycle operations.

4) Security, Compliance & Governance

· Enforce identity security baseline: least privilege, tiering model, administrative boundaries, and secure admin workstations.

· Support audits by providing evidence: access reviews, privileged role logs, change records, and security reports.

· Implement and maintain RBAC, delegated admin permissions, and standard operating procedures for identity operations.

· Drive remediation for vulnerabilities and security findings related to directory services and identity components.

5) Operations, Monitoring & ITSM Processes

· Provide L2/L3 support for incidents and service requests related to AD, Entra ID, SSO, and authentication.

· Manage changes through Change Management, create implementation plans, rollback procedures, and conduct PIRs/RCA.

· Maintain monitoring dashboards and alerts for AD DS, DNS, AAD Connect, Entra sign-in activity, and service health.

· Create and maintain knowledge articles, runbooks, SOPs, and operational documentation.

6) Integration & Stakeholder Collaboration

· Work with Security/IAM teams on access governance, privileged access, and policy enforcement.

· Collaborate with Messaging/M365, Endpoint, Network, and Application teams for identity integrations and SSO enablement.

· Provide technical inputs for enhancements, standardization, and continuous improvement of identity services.

Deliverables / Expected Outcomes

· Stable and secure AD DS and Entra ID operations with minimal incidents.

· Consistent enforcement of identity governance (MFA/CA/PIM, privileged access, access reviews).

· Healthy synchronization and authentication across hybrid workloads (Azure AD Connect, SSO).

· Audit-ready evidence and updated documentation (SOPs, diagrams, runbooks, baseline policies).
