πŸ” Blog – Identity Lifecycle Management: Automating Access from Hire to Exit

Welcome back to the sixth post of my first blog series here on Dev, where we’re tackling the most essential β€” yet often neglected β€” piece of Identity Management: Identity Lifecycle Management (ILM).

Whether you're managing Windows Servers, Azure AD environments, or mixed infrastructures, understanding ILM will help you eliminate manual mistakes, automate compliance and streamline operations.

πŸ” What is Identity Lifecycle Management?
Identity Lifecycle Management (ILM) refers to the end-to-end process of creating, managing and deleting user identities as they progress through their lifecycle:

  1. Onboarding (Joiners)
  2. Movement (Movers)
  3. Offboarding (Leavers)

Done right, ILM ensures:

  • Users have the right access at the right time.
  • No orphaned accounts after someone leaves.
  • Reduced security risks and audit gaps.

🏒 1. ILM in Windows Server (Active Directory)
πŸ“₯ Onboarding (Joiners):
Use PowerShell scripts or HR system triggers to create users automatically.

Assign them to the right Organizational Units (OUs) and security groups.

powershell

New-ADUser -Name "Vaibhav Agwane" -GivenName "Vaibhav" -Surname "Agwane" -SamAccountName "vaibhav.a"
-UserPrincipalName "vaibhav.a@yourdomain.com" -Path "OU=Dev,DC=yourdomain,DC=com"

-AccountPassword (ConvertTo-SecureString "Temp@1234" -AsPlainText -Force) -Enabled $true

πŸ”„ Movers:

  • Automate role-based group changes using group membership automation or scripts.
  • Move users between OUs using policies for access control and GPO enforcement.

powershell

Move-ADObject -Identity "CN=Shubham Agasti,OU=Dev,DC=yourdomain,DC=com" -TargetPath "OU=Managers,DC=yourdomain,DC=com"

❌ Offboarding:

  • Disable account immediately, move to "Disabled Users" OU.
  • Schedule account deletion and home folder cleanup.
  • Log actions for audits.

☁️ 2. ILM in Azure Active Directory
Azure AD offers cloud-native, policy-driven automation:

πŸ“₯ Onboarding:
Dynamic Groups assign licenses, apps and roles based on user attributes (e.g., department = 'Engineering').

Provisioning from HR systems (e.g., Workday) using SCIM (System for Cross-domain Identity Management).

πŸ”„ Movers:

  • Changes in department, title, or location auto-update user’s group membership and access.
  • Conditional Access adapts based on updated user risk or device compliance.

❌ Offboarding:

  • Immediate account block via Azure AD portal or Graph API.
  • Use Access Reviews to clean up group memberships.
  • Trigger Just-In-Time (JIT) access removal workflows with Microsoft Entra ID Governance.

powershell

Disable a user in Azure AD

Set-AzureADUser -ObjectId "user@domain.com" -AccountEnabled $false

🐧 3. ILM in Linux Server (OpenLDAP or Integrated with AD)
Linux ILM typically ties into AD or OpenLDAP. Use these tools:

πŸ“₯ Onboarding:
If integrated with AD, accounts are auto-available via SSSD/realmd.

For OpenLDAP, use ldapadd scripts or tools like FusionDirectory to create users.

bash

sudo ldapadd -x -D "cn=admin,dc=example,dc=com" -W -f new_user.ldif
πŸ”„ Movers:

  • Update user attributes via ldapmodify.
  • Map LDAP groups to sudoers or access policies.

❌ Offboarding:

  • Use ldapdelete or AD user disablement to revoke access.
  • Monitor Linux auth logs for last login β€” useful for determining inactive users.

πŸ›‘οΈ Best Practices for ILM
βœ… Disable accounts instead of immediate deletion β€” retain for forensic/audit purposes.

βœ… Use Least Privilege model β€” access only as needed.

βœ… Automate via event-driven triggers (e.g., new hire email from HR).

βœ… Regular Access Reviews and attestation.

βœ… Multi-system synchronization (AD + Azure AD + Apps).

🧩 Wrapping Up
Identity Lifecycle Management is more than user creation. It's a strategic capability that ensures security, compliance and efficiency across your IT environment β€” whether in the cloud or on-prem.

Start small: automate onboarding, then build toward full lifecycle automation.
