? Blog – Identity Lifecycle Management: Automating Access from Hire to Exit

[Lomanu4]

Welcome back to the sixth post of my first blog series here on Dev, where we’re tackling the most essential — yet often neglected — 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.

? 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)
? 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

? 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:

? 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).

? 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:

? 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
? 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 — useful for determining inactive users.

?️ Best Practices for ILM
Disable accounts instead of immediate deletion — retain for forensic/audit purposes.

Use Least Privilege model — access only as needed.

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

Regular Access Reviews and attestation.

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 — whether in the cloud or on-prem.

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