Microsoft Identity Manager 2016 Synchronization Service

Microsoft Identity Manager (MIM) 2016 Synchronization Service is a powerful identity synchronization platform that enables organizations to manage and synchronize identity data across multiple disparate systems. This document provides a comprehensive high-level overview of the service, its architecture, capabilities, and use cases.

What is MIM 2016 Synchronization Service?

The Microsoft Identity Manager 2016 Synchronization Service (formerly known as Forefront Identity Manager or FIM Synchronization Service) is the core synchronization engine within the MIM suite. It serves as a central hub for identity data synchronization, enabling organizations to:

  • Synchronize identities across multiple connected data sources
  • Transform and map identity attributes between different systems
  • Maintain data consistency across heterogeneous environments
  • Automate identity lifecycle management processes
  • Enforce business rules through custom logic and workflows
Note

The Synchronization Service can operate independently of the MIM Service and Portal, making it a lightweight solution for pure synchronization scenarios.

Architecture Overview

Core Components

The MIM 2016 Synchronization Service consists of several key components that work together to provide comprehensive identity synchronization capabilities:

1. Synchronization Engine

The Synchronization Engine is the heart of the service, responsible for:

  • Data processing: Reading, transforming, and writing identity data
  • Rule evaluation: Applying synchronization rules and business logic
  • Conflict resolution: Handling data conflicts and inconsistencies
  • Change tracking: Monitoring and processing data changes
  • Workflow orchestration: Coordinating synchronization operations

2. Metaverse

The Metaverse serves as the authoritative identity store within MIM:

  • Central repository: Stores the unified view of each identity
  • Schema definition: Defines the structure and attributes of identity objects
  • Relationship management: Maintains connections between related objects
  • Data consolidation: Combines data from multiple connected systems
  • Authoritative source: Provides the single source of truth for identities

3. Connector Space

Connector Spaces represent the staging areas for connected data sources:

  • Data staging: Temporarily stores data from connected systems
  • Change detection: Identifies modifications in source systems
  • Transformation preparation: Prepares data for processing rules
  • Isolation: Keeps each system's data separate during processing
  • Synchronization coordination: Manages the flow of data to/from systems

4. Management Agents (MAs)

Management Agents are the connectors that interface with external systems:

  • Data source connectivity: Establish connections to various systems
  • Protocol support: Handle different communication protocols and formats
  • Import/Export operations: Facilitate data transfer operations
  • Change detection: Monitor source systems for modifications
  • Error handling: Manage connectivity and data processing errors
