Microsoft Entra ID | Identity & Access Management | Role-Based Access Control (RBAC)
Overview
In this lab, I validated Microsoft Entra ID privileged role assignments for the Global Administrator role to confirm identity consistency and assess whether apparent duplicate entries in the portal represented actual RBAC duplication or only a UI-level representation.
The focus of this exercise was not simply role identification, but understanding how Entra ID models privileged access at the identity and assignment layer.
- Objective
The objective of this lab was to:
- Identify Global Administrator role assignments within Microsoft Entra ID
- Validate the associated identity using Object ID
- Confirm Role Definition ID consistency
- Investigate whether duplicate entries in the portal represent actual RBAC duplication
- Understand how privileged roles are represented in Entra ID
This lab builds on foundational Azure environment setup by introducing identity governance and privileged access validation.
- Environment and Configuration
This lab was performed in:
- Microsoft Entra admin centre
- Directory: Default Directory
- Role: Global Administrator
Key identifiers:
- Principal ID: e725c212-4d94-4ae4-9bf1-62422d7bac76
- Role Definition ID: 62e90394-69f5-4237-9190-012177145e10
- Scope: Directory (Default Directory)
- Assignment Type: Direct
- Key Steps Performed
3.1 Accessing Role Management
Navigated to:
Microsoft Entra ID → Roles and administrators → Global Administrator
From here, I accessed the role assignment view to review all assigned principals.
3.2 Reviewing Role Assignments
Within the Global Administrator role, a single identity was observed:
- The same Principal ID appeared consistently across entries
- The same Role Definition ID was associated with the assignment
- Scope remained at the directory level
3.3 UI Observation and Investigation
Multiple entries appeared visually in the portal under the same role context.
However, each entry shared identical backend identifiers:
- Principal ID
- Role Definition ID
- Directory scope
This suggested a presentation-layer duplication, rather than multiple RBAC assignments.
3.4 Validation of Identity Consistency
Cross-checking confirmed:
- One unique Principal ID
- One Role Definition ID
- One directory-scoped assignment
No evidence of multiple distinct assignments was found.
- Evidence
The following evidence supports the findings:
- Global Administrator role visible in Entra ID
- Principal ID: e725c212-4d94-4ae4-9bf1-62422d7bac76
- Role Definition ID: 62e90394-69f5-4237-9190-012177145e10
- Consistent assignment scope: Default Directory
- No duplicate RBAC assignment detected at backend level
- Operational Interpretation
From an identity governance perspective, this lab highlights an important distinction between:
- UI representation of role assignments
- Underlying RBAC data model
In Microsoft Entra ID:
- Role assignments are uniquely defined by Principal ID + Role Definition ID + Scope
- Portal views may aggregate or visually repeat entries depending on UI context
- Apparent duplication does not necessarily indicate security misconfiguration
- Key Learning Outcome
This lab reinforced a critical IAM principle:
Identity and access validation must be based on backend identifiers, not portal presentation.
Key concepts reinforced:
- Role-Based Access Control (RBAC) structure in Entra ID
- Object ID as a stable identity anchor
- Role Definition ID as a privileged role identifier
- Separation between UI and actual access control state
- Conclusion
This lab confirmed that the Global Administrator role assignment exists as a single, consistent privileged identity mapping within Microsoft Entra ID.
While the portal interface may suggest duplication, backend validation shows a single authoritative assignment.
This exercise reinforces the importance of structured identity validation when working with privileged roles in enterprise environments.
Repository Context
This lab is part of a structured Azure and identity security learning progression focused on:
- Microsoft Entra ID identity governance
- Privileged access management concepts
- Role-based access control validation
- SOC-style identity investigation methodology
