The ForgeRock Certified IDM Specialist certification validates your expertise in implementing and managing ForgeRock Identity Management solutions. This guide provides everything you need to prepare for and pass the exam.

What is ForgeRock IDM?

ForgeRock Identity Management (IDM) is an enterprise-grade identity governance and provisioning platform that enables:

• User Lifecycle Management – Joiner, mover, leaver automation
• Identity Synchronization – Real-time sync between systems
• Self-Service Capabilities – Password reset, profile management
• Workflow Orchestration – Approval workflows and business processes
• Reconciliation – Detecting and resolving identity data discrepancies

Exam Overview

Exam Domains and Objectives

Domain 1: IDM Architecture and Installation (15%)

Key Topics:

• IDM deployment models (standalone, clustered)
• Repository configuration (embedded DS, external DS, JDBC)
• Boot properties and system configuration
• Project structure and file organization
• Upgrade and migration procedures

What You Should Know:

conf/
├── boot/
│   └── boot.properties      # JVM and startup settings
├── config.properties        # IDM configuration
├── logging.properties       # Log configuration
└── resolver/               # Object mappings
    └── *.json

script/
├── onCreate/               # Object creation scripts
├── onUpdate/               # Update trigger scripts
└── onDelete/               # Deletion scripts

Domain 2: Managed Objects and Schema (20%)

This is a critical domain covering how IDM stores and manages identity data.

Key Concepts:

• Managed object definitions
• Schema design and properties
• Relationships between objects
• Virtual properties and calculated values
• Object lifecycle states

Example Managed Object Schema:

{
  "name": "user",
  "schema": {
    "properties": {
      "userName": { "type": "string", "required": true },
      "givenName": { "type": "string" },
      "sn": { "type": "string" },
      "mail": { "type": "string", "format": "email" },
      "accountStatus": {
        "type": "string",
        "enum": ["active", "inactive", "staged"]
      },
      "manager": {
        "type": "relationship",
        "reverseRelationship": true,
        "properties": {
          "_ref": { "type": "string" },
          "_refProperties": {
            "type": "object"
          }
        }
      }
    }
  }
}

Domain 3: Connectors and External Systems (25%)

The most heavily weighted domain. Focus extensively on:

• Connector types (LDAP, Scripted, Database, REST)
• Connector configuration and pooling
• Object type mappings
• Attribute flow (source → IDM → target)
• Scripted connectors (Groovy)

Common Connector Configurations:

Scripted Connector Example:

// SearchScript.groovy
import org.forgerock.openicf.connectors.groovy.OperationType
import org.identityconnectors.framework.common.objects.*

def operation = operation as OperationType
def objectClass = objectClass as ObjectClass
def filter = filter
def options = options as OperationOptions

// Query external system
def results = httpClient.get("/api/users")

results.each { user ->
    handler {
        uid user.id
        id user.username
        attribute 'firstName', user.firstName
        attribute 'lastName', user.lastName
        attribute 'email', user.email
    }
}

Domain 4: Synchronization and Reconciliation (20%)

Critical for exam success:

• Mapping configurations
• Source and target sync
• Correlation and situation handling
• Reconciliation types (full, incremental)
• LiveSync configuration
• Conflict resolution

Synchronization Situations:

Mapping Configuration Example:

{
  "name": "systemHrAccounts_managedUser",
  "source": "system/hr/account",
  "target": "managed/user",
  "correlationQuery": {
    "type": "text/javascript",
    "source": "{'_queryFilter': 'employeeId eq \"' + source.empId + '\"'}"
  },
  "properties": [
    {
      "source": "empId",
      "target": "employeeId"
    },
    {
      "source": "firstName",
      "target": "givenName"
    },
    {
      "source": "",
      "transform": {
        "type": "text/javascript",
        "source": "source.firstName + '.' + source.lastName + '@company.com'"
      },
      "target": "mail"
    }
  ]
}

Domain 5: Workflows and Business Processes (10%)

• BPMN workflow definitions
• Approval processes
• Task management
• Email notifications
• Custom workflow nodes

Domain 6: Security and Access Control (10%)

• Authentication configuration
• Authorization policies
• Role-based access control
• Audit logging
• Secure communication (TLS)

Hands-On Lab Exercises

Lab 1: Basic Connector Setup

Set up a CSV connector to import users:

1. Create a CSV file with user data
2. Configure the CSV connector in provisioner.openicf-csv.json
3. Define object mappings
4. Run reconciliation
5. Verify users in managed/user

Lab 2: Synchronization Mapping

Create a mapping from HR system to IDM:

1. Define source (HR connector)
2. Define target (managed/user)
3. Configure correlation rules
4. Set up attribute mappings with transforms
5. Handle all synchronization situations

Lab 3: Scripted Connector Development

Build a custom REST connector:

1. Create Groovy scripts for CRUD operations
2. Configure HTTP client settings
3. Implement pagination for large datasets
4. Add error handling
5. Test with reconciliation

Key Differences: AM vs IDM Certification

Exam Day Tips

1. Time Management – 90 minutes for ~60 questions = ~90 seconds per question
2. Read Carefully – Scenario questions require understanding the full context
3. Eliminate Obviously Wrong – Narrow down to 2 options, then decide
4. Flag and Return – Don’t get stuck; mark difficult questions for review
5. Trust Your Experience – Real-world IDM work is the best preparation
