Azure Active Directory Guide: From Basic to Advanced with Scripts
1. Introduction to Azure AD
Before diving into configuration and scripting, let’s quickly recap what Azure AD is and its core functionality:
2. Setting Up and Configuring Azure AD (Basic Level)
2.1. Azure AD Subscription
To get started with Azure AD:
2.2. User Management (PowerShell Example)
Create a User Manually via Portal:
Bulk Create Users via PowerShell:
You can use PowerShell to automate user creation in Azure AD.
PowerShell Script: Bulk User Creation via CSV
# Import the AzureAD module
Install-Module AzureAD
# Sign in to Azure AD
Connect-AzureAD
# Import users from CSV file
$users = Import-Csv -Path "C:\Path\To\your\users.csv"
foreach ($user in $users) {
New-AzureADUser -DisplayName $user.Name -UserPrincipalName $user.UserPrincipalName -PasswordProfile @{ ForceChangePasswordNextSignIn = $true; Password = "TempPassword123" } -MailNickName $user.MailNickName -UserType "Member"
}
CSV Format Example:
Name
UserPrincipalName
MailNickName
John Doe
john.doe@contoso.com
john.doe
Jane Smith
jane.smith@contoso.com
jane.smith
2.3. Group Management
Create a Group via PowerShell:
# Create a new security group
New-AzureADGroup -DisplayName "Marketing Team" -MailEnabled $false -SecurityEnabled $true -MailNickname "marketingteam"
Dynamic Group Example:
To create a dynamic group where all users in the Marketing department are automatically added:
$rule = New-AzureADMSGroupLifecyclePolicy -GroupId "marketinggroup" -UserMemberSettings "None" -GroupMembershipRule "user.department -eq 'Marketing'"
2.4. Role-based Access Control (RBAC)
Assigning a Role to a User via PowerShell:
# Get the "User Administrator" role
$role = Get-AzureADDirectoryRole | Where-Object {$_.DisplayName -eq "User administrator"}
# Assign role to a user
Add-AzureADDirectoryRoleMember -ObjectId $role.ObjectId -RefObjectId (Get-AzureADUser -SearchString "john.doe@contoso.com").ObjectId
Best Practice: Always apply the principle of least privilege. Only assign necessary roles to users and groups.
3. Identity Management and Security (Intermediate Level)
3.1. Multi-Factor Authentication (MFA)
Enabling MFA for a User via PowerShell:
# Install the MSOnline module if not already installed
Install-Module MSOnline
# Connect to Azure AD
Connect-MsolService
# Enable MFA for a specific user
Set-MsolUser -UserPrincipalName "john.doe@contoso.com" -StrongAuthenticationRequirements @(@{State="Enabled"})
3.2. Self-Service Password Reset (SSPR)
Configuring SSPR:
To enable SSPR:
Example:
# Enable self-service password reset for a user
Set-MsolUserPassword -UserPrincipalName "john.doe@contoso.com" -ForceChangePassword $true
3.3. Conditional Access Policies
Create Conditional Access Policy for MFA:
# Create a conditional access policy
New-AzureADMSConditionalAccessPolicy -DisplayName "Require MFA for external logins" -State "enabled" -Conditions @{
SignInRiskLevels = "High"
Locations = @{
Include = "All"
Exclude = "Trusted Locations"
}
} -Actions @{
SignInRiskLevel = "High"
AccessControls = "MFA"
}
3.4. Identity Protection
Risk-Based Policies Example:
# Configure a policy to block access if high-risk sign-ins are detected
New-AzureADMSIdentityProtectionPolicy -DisplayName "Block high-risk sign-ins" -State "enabled" -RiskLevel "High" -AccessControls "Block"

csharp
// Using Microsoft Graph API to create a B2C user:
GraphServiceClient graphClient = new GraphServiceClient(authProvider);
User newUser = new User
{
DisplayName = "John Doe",
UserPrincipalName = "john.doe@yourtenant.onmicrosoft.com",
PasswordProfile = new PasswordProfile
{
ForceChangePasswordNextSignIn = true,
Password = "TempPassword123"
}
};
await graphClient.Users.Request().AddAsync(newUser);
9. Advanced Automation with Azure AD
9.1. Automating User Lifecycle Management
Automatically Assign Users to Groups Based on Attributes:
You can automate the process of adding users to specific groups based on their department or other attributes.
PowerShell Script to Add Users to Group Based on Department:
# Get users where department is 'Finance'
$users = Get-AzureADUser -Filter "Department eq 'Finance'"
# Get the group you want to add users to
$group = Get-AzureADGroup -SearchString "Finance Group"
foreach ($user in $users) {
Add-AzureADGroupMember -ObjectId $group.ObjectId -RefObjectId $user.ObjectId
}
Best Practice: Automate the assignment of users to groups based on role or department. This ensures that users are always in the correct group without manual intervention.
9.2. Automating User Deactivation and Cleanup:
Set up an automation process to deactivate or delete users who have left the organization.
PowerShell Script to Delete Users After 90 Days of Inactivity:
# Get inactive users (no sign-ins for 90 days)
$inactiveUsers = Get-AzureADUserSignInActivity -Filter "lastSignInDateTime lt '$(Get-Date).AddDays(-90)'"
foreach ($user in $inactiveUsers) {
Remove-AzureADUser -ObjectId $user.ObjectId
}
Best Practice: Implement automated cleanup for user accounts that have been inactive for a specific period to prevent unauthorized access.
9.3. Automation Using Azure Logic Apps:
Azure Logic Apps can be used for workflow automation in Azure AD.
Example Scenario: Automatically notify HR and IT when a user is created or deactivated.
Steps:

"definition": {
"schema": {
"properties": {
"trigger": {
"type": "AzureEventGridTrigger",
"properties": {
"events": [
"Microsoft.DirectoryServices.UserCreated",
"Microsoft.DirectoryServices.UserDeleted"
]
}
},
"action": {
"type": "SendEmail",
"properties": {
"To": "hr@yourcompany.com",
"Subject": "New User Created",
"Body": "A new user has been created: {{trigger.eventData.userPrincipalName}}"
}
}
}
}
}
}
10. Security and Compliance
10.1. Azure AD Conditional Access Policies (Advanced)
Scenario: Restrict access to corporate data from unmanaged devices.
You can enforce conditional access to block access from devices that are not compliant with your security policies (e.g., not enrolled in Intune).
PowerShell for Conditional Access Policy:
New-AzureADMSConditionalAccessPolicy -DisplayName "Block Access from Non-Compliant Devices" -State "enabled" -Conditions @{
DeviceState = "Unmanaged"
} -Actions @{
BlockAccess = $true
}
Best Practice:
10.2. Azure AD Privileged Identity Management (PIM)
Azure AD Privileged Identity Management (PIM) helps manage elevated access for users (e.g., global administrators).
Enable PIM:
# Enable Privileged Identity Management
Enable-AzureADPrivilegedIdentityManagement
Activate a Role Using PIM:
# Activate a role in PIM for a user
New-AzureADMSPrivilegedRoleAssignment -ProviderId "aadRoles" -RoleDefinitionId <RoleDefinitionId> -ResourceId <ResourceId> -PrincipalId <UserObjectId> -AssignmentType "User"
Best Practice: Use Just-In-Time (JIT) elevation for admin roles to minimize the attack surface.
11. Troubleshooting Azure AD
11.1. Azure AD Sign-in Troubleshooting
Troubleshoot Failed Sign-ins:
PowerShell Example for Reviewing Sign-In Logs:
# Retrieve the last 10 failed sign-ins
Get-AzureADAuditSignInLogs | Where-Object { $_.Status.ErrorCode -ne 0 } | Select-Object UserPrincipalName, CreatedDateTime, Status, ErrorCode | Select-Object -First 10
11.2. Sync Issues with Azure AD Connect
Use Azure AD Connect Health to monitor synchronization between on-premise AD and Azure AD.
PowerShell to Check Sync Health:

13.1. Azure AD Integration with Microsoft 365
Automating Microsoft 365 License Assignment:
You can automate license assignment based on Azure AD user attributes. For example, assign Microsoft 365 licenses to users based on their department or job title.
PowerShell Script to Assign License Based on Department:
# Connect to Azure AD
Connect-AzureAD
# Define the department-based license assignment
$users = Get-AzureADUser -Filter "Department eq 'Sales'"
# Define the Microsoft 365 license (replace with your actual SKU ID)
$license = New-Object -TypeName Microsoft.Open.AzureAD.Model.AssignedLicense -ArgumentList "sku-id-here"
foreach ($user in $users) {
Set-AzureADUserLicense -ObjectId $user.ObjectId -AssignedLicenses $license
}
Best Practice: Create dynamic groups in Azure AD and assign licenses to the group rather than individual users for better manageability.
13.2. Azure AD and Azure Key Vault
Azure AD can be used for authentication to Azure Key Vault, allowing secure access to secrets, certificates, and keys.
Using Azure AD for Key Vault Authentication:
PowerShell to Grant Access to Key Vault:
# Create Service Principal
$sp = New-AzureADServicePrincipal -AppId "your-app-id"
# Grant access to the Key Vault
Set-AzureKeyVaultAccessPolicy -VaultName "your-keyvault-name" -ServicePrincipalName $sp.AppId -PermissionsToSecrets get,list
13.3. Azure AD and Azure Sentinel (SIEM Integration)
Azure AD can be integrated with Azure Sentinel for security incident and event management (SIEM).
Set Up Azure AD Logs in Azure Sentinel:
PowerShell Example to Monitor Suspicious Activity:
# Query the sign-in logs for failed sign-ins in the last 24 hours
Search-AzureADSignInLogs -Filter "Status/ErrorCode eq 50053" -StartDate (Get-Date).AddDays(-1) -EndDate (Get-Date)
This can help detect suspicious activity, such as brute-force attacks or unusual sign-in locations.
14. Advanced User Management and Automation
14.1. Dynamic Group Membership
Dynamic groups can automatically add or remove members based on attributes such as department, job title, or location. This is a key feature for automating access control.
Create a Dynamic Group for Users in the HR Department:
# Create a dynamic group with the rule for 'HR' department
New-AzureADMSGroup -DisplayName "HR Group" -MailEnabled $false -SecurityEnabled $true -MailNickname "HRGroup" -GroupTypes "DynamicMembership" -MembershipRule "(user.department -eq 'HR')" -MembershipRuleProcessingState "On"
Best Practice: Use dynamic groups for role-based access control (RBAC) and automate membership based on attributes. This minimizes manual errors and ensures users always have the right access based on their role.
14.2. Managing External Collaboration Settings
Azure AD allows you to configure external collaboration settings for B2B users, controlling what external users can see or access in your environment.
PowerShell Script to Configure External User Invitations:
You can enable or restrict the ability of external users to join your directory.
# Enable invitations to be sent to external users
Set-AzureADDirectorySetting -Id "ExternalCollaborationSetting" -ExternalUserInviteRedirectUrl "https://yourcompany.com/invite" -AllowInvitesFrom "All" -AllowEmailVerifiedUsersOnly $false
Best Practice: Regularly audit external users and ensure proper restrictions are in place to prevent over-permissioned external users.
15. Monitoring and Auditing
15.1. Azure AD Audit Logs for Security and Compliance
Azure AD Audit Logs track all actions taken in your tenant, including changes in user roles, group memberships, and permissions.
PowerShell to Export Audit Logs:
# Export audit logs from Azure AD
Get-AzureADAuditDirectoryLogs -Filter "activityDisplayName eq 'Add member to group'" | Export-Csv "C:\AuditLogs.csv" -NoTypeInformation
This helps maintain audit trails for compliance purposes, ensuring that any actions taken within Azure AD are logged for future reference.
15.2. Azure AD Sign-In Logs for Threat Detection
Azure AD Sign-In logs can be used to detect and mitigate failed logins, risky sign-ins, or suspicious activity.
PowerShell to Retrieve Failed Sign-ins in Last 30 Days:
# Get sign-in logs where status error code indicates failure
Get-AzureADAuditSignInLogs -Filter "Status/ErrorCode ne 0" -StartDate (Get-Date).AddDays(-30) | Select-Object UserPrincipalName, Status, CreatedDateTime
You can integrate these logs with Azure Sentinel for real-time threat monitoring.
16. Best Practices for Large-Scale Azure AD Deployments
16.1. Implement Role-Based Access Control (RBAC)
Azure AD allows you to control who has access to which resources, reducing the attack surface.
Best Practice:
Assign a Custom Role to a User:
# Create custom role (example)
$customRole = New-AzureADMSRoleDefinition -DisplayName "Custom Admin" -Description "Custom role for administration" -IsEnabled $true -RoleTemplateId "your-template-id"
# Assign role to user
Add-AzureADMSRoleAssignment -ProviderId "aadRoles" -RoleDefinitionId $customRole.Id -ResourceId "your-resource-id" -PrincipalId "user-object-id"
16.2. Plan for Global and Regional Redundancy
When implementing Azure AD at scale, consider multi-region deployments to ensure high availability and disaster recovery.
16.3. Automate User Offboarding:
Offboarding is critical in large-scale environments to prevent unauthorized access.
PowerShell to Offboard Users:
# Disable and remove a user (example: user leaves the company)
Set-AzureADUser -ObjectId "user-object-id" -AccountEnabled $false
Remove-AzureADUser -ObjectId "user-object-id"
Automate this process as part of your workflow management using Azure Logic Apps or Power Automate.
17. Advanced Security Features in Azure AD
17.1. Azure AD Identity Protection
Azure AD Identity Protection can automate the detection of risk events and enforce protective actions.
PowerShell to Create a Risk-Based Conditional Access Policy:
# Create a conditional access policy to block risky sign-ins
New-AzureADMSConditionalAccessPolicy -DisplayName "Block Risky Sign-Ins" -State "enabled" -Conditions @{
UserRiskLevels = "High"
} -Actions @{
BlockAccess = $true
}
You can configure these policies to automatically protect user accounts based on sign-in risk levels and other risk indicators.
17.2. Azure AD Privileged Identity Management (PIM) for Role Management
PIM allows you to manage elevated admin privileges and just-in-time (JIT) access to admin roles.
PowerShell to Enable PIM:
# Enable Privileged Identity Management (PIM)
Enable-AzureADPrivilegedIdentityManagement
PIM can be configured to audit every role activation and automatically notify admins of role assignments.
18. Conclusion and Key Takeaways
19. Advanced Azure AD Security and Governance
19.1. Azure AD Conditional Access with MFA (Multi-Factor Authentication)
One of the core components of Azure AD Security is enforcing Multi-Factor Authentication (MFA). Conditional Access policies can dynamically require MFA under specific conditions, such as risky sign-ins or access to sensitive resources.
Scenario: Require MFA for Access to Specific Apps (e.g., Microsoft 365)
You can set up Conditional Access policies to require MFA for accessing Microsoft 365 apps only when users are signing in from unfamiliar locations or devices.
# Create a Conditional Access policy to enforce MFA when accessing Microsoft 365 apps
New-AzureADMSConditionalAccessPolicy -DisplayName "Require MFA for Microsoft 365" -State "enabled" -Conditions @{
Applications = @("Office365")
Locations = "Unfamiliar"
} -Actions @{
Grant = "RequireMultiFactorAuthentication"
}
Best Practice: Always require MFA for high-risk actions (like accessing critical resources or changing security settings) and for users outside your corporate network. Configure risk-based conditional access to block or enforce MFA for risky logins.
19.2. Azure AD Identity Protection for Risk-Based Policies
Azure AD Identity Protection is a powerful tool that uses machine learning and heuristics to detect potential security risks in user behavior, such as sign-ins from unfamiliar locations or suspicious activity.
Creating a Risk Policy to Block Sign-In from Unfamiliar Locations:
You can configure Identity Protection to detect high-risk sign-ins and take action, such as blocking access or requiring MFA.
PowerShell to Enable Risk-Based Conditional Access Policy:
# Enable conditional access to block risky sign-ins
New-AzureADMSConditionalAccessPolicy -DisplayName "Block Risky Sign-Ins" -State "enabled" -Conditions @{
RiskLevels = "High"
} -Actions @{
BlockAccess = $true
}
Best Practice: Integrate Azure AD Identity Protection with Conditional Access for a multi-layered security approach.
19.3. Azure AD Privileged Identity Management (PIM) for Enhanced Role Management
PIM enables Just-In-Time (JIT) access to elevated roles in Azure AD, reducing the attack surface by ensuring that administrators only have the necessary permissions for a limited time.
Configure Role Eligibility and Assignments via PIM:
You can configure PIM for roles like Global Administrator or Security Administrator to ensure that users only activate these roles when necessary.
# Assign a role using PIM
New-AzureADMSPrivilegedRoleAssignment -ProviderId "aadRoles" -RoleDefinitionId "<RoleDefinitionId>" -ResourceId "<ResourceId>" -PrincipalId "<UserObjectId>"
Best Practice: Enforce approval workflows and audit logs for role activations and removals in PIM. Use MFA for role activation to add an additional layer of security.
20. Azure AD Integration with Third-Party Applications
20.1. Integrating Azure AD with SaaS Applications for Single Sign-On (SSO)
Azure AD supports SSO integration with thousands of SaaS apps. Integrating apps into Azure AD allows users to authenticate with their Azure AD credentials rather than having separate credentials for each service.
Add a New App to Azure AD for SSO:
You can configure apps manually or automatically using the Enterprise Applications section in Azure AD.
PowerShell to Configure SSO for an Application:
# Set SSO for a particular app (replace with your app's details)
$application = Get-AzureADApplication -Filter "DisplayName eq 'Salesforce'"
Set-AzureADApplication -ObjectId $application.ObjectId -Web @{HomePage = "https://www.salesforce.com"}
Best Practice: Enable SSO for all external applications to simplify the user experience and improve security by centralizing user authentication.
20.2. Azure AD Integration with AWS for Cross-Cloud Identity Management
You can configure Azure AD as the identity provider (IdP) for AWS and use SAML-based authentication to manage AWS access.
Steps:
Best Practice: Integrating Azure AD with AWS and other cloud providers reduces the complexity of managing user identities across multiple clouds. Use Role-Based Access Control (RBAC) to align permissions between the two systems.
21. Azure AD and Active Directory Federation Services (ADFS)
21.1. Configuring Federation with ADFS for Hybrid Identity
In hybrid identity scenarios, where both on-premises Active Directory and Azure AD are used, ADFS can provide seamless SSO.
Steps to Configure ADFS for Federation:
PowerShell Example to Configure Federation:
# Check ADFS status for your domain
Get-MsolDomainFederationSettings -DomainName "contoso.com"
# Configure ADFS federation for your domain
Set-MsolDomainAuthentication -DomainName "contoso.com" -FederationBrandName "Contoso Federation" -Authentication Federated
Best Practice: Use ADFS for hybrid scenarios where on-premises identities need to be preserved in Azure AD. Ensure backup and disaster recovery for ADFS to avoid service outages.
22. Advanced User Lifecycle Management and Automation
22.1. Automating User Creation, Assignment, and Offboarding
Automating the entire lifecycle from user creation to offboarding can significantly improve administrative efficiency.
PowerShell Script to Automatically Assign User to Groups Based on Role:
This script automates user creation and assigns them to the correct roles and groups based on their department.
# Create a user
$newUser = New-AzureADUser -UserPrincipalName "jdoe@contoso.com" -DisplayName "John Doe" -PasswordProfile @{ ForceChangePasswordNextSignIn = $true; Password = "TempPassword123" }
# Assign the user to a group based on department
$group = Get-AzureADGroup -SearchString "Sales"
Add-AzureADGroupMember -ObjectId $group.ObjectId -RefObjectId $newUser.ObjectId
Automated Offboarding (Disabling and Deleting Users):
This script will automatically disable and delete users after 30 days of inactivity.
# Find inactive users and disable/delete them
$inactiveUsers = Get-AzureADUser -All $true | Where-Object { $_.LastSignInDateTime -lt (Get-Date).AddDays(-30) }
foreach ($user in $inactiveUsers) {
Set-AzureADUser -ObjectId $user.ObjectId -AccountEnabled $false
Remove-AzureADUser -ObjectId $user.ObjectId
}
Best Practice: Implement a user lifecycle management process that automates the creation, role assignment, and offboarding of users, ensuring security and compliance while minimizing manual errors.
23. Best Practices for Large-Scale Azure AD Operations
23.1. Implement Role-Based Access Control (RBAC) at Scale
For large organizations, managing access via RBAC ensures that users have only the necessary permissions. By using custom roles and groups, you can enforce the principle of least privilege.
PowerShell to Create a Custom Role:
# Create a custom role with limited permissions (e.g., read-only access)
New-AzureADMSRoleDefinition -DisplayName "ReadOnlyRole" -Description "Can read directory data" -IsEnabled $true -RolePermissions @(
@{PermissionName = "Directory.Read.All"}
)
23.2. Plan for Disaster Recovery and Redundancy
Azure AD provides geo-redundancy by default, but consider setting up custom alerts for critical issues. Ensure that backup authentication methods like ADFS are configured in case of Azure AD outages.
Best Practice: Always have a backup plan that includes Geo-Redundant configurations and cross-region synchronization for critical operations.
24. Advanced Hybrid Identity Management
24.1. Azure AD Connect: Deep Dive into Synchronization
Azure AD Connect is a vital tool for organizations with hybrid environments (on-premises Active Directory and Azure AD). It ensures that users and groups are synchronized between both directories. Let’s explore advanced scenarios with Azure AD Connect.
24.1.1. Use of Custom Synchronization Filters
Sometimes you may need to synchronize a subset of objects from your on-premises Active Directory to Azure AD. Azure AD Connect allows for custom filtering of users, groups, or organizational units (OUs).
PowerShell Example: Filtering Specific Organizational Units (OUs)
# Set synchronization rules to only sync specific OUs
Set-ADSyncAADDomainService -DomainController "yourdomaincontroller" -SyncRules "OU=Sales,DC=contoso,DC=com"
Best Practice: Limit synchronization to only necessary organizational units (OUs) and avoid syncing the entire directory. This minimizes the attack surface and optimizes performance.
24.2. Azure AD B2C (Business to Consumer)
For customer-facing applications, Azure AD B2C allows you to implement SSO and custom authentication for users outside your organization. It provides a scalable identity management solution for customer applications.
PowerShell Example: Configure Custom Identity Providers (e.g., Google)
# Create a new B2C identity provider for Google
New-AzureADMSIdentityProvider -Type "Google" -DisplayName "Google B2C" -ClientId "your-client-id" -ClientSecret "your-client-secret"
Best Practice: Use Azure AD B2C for customer or third-party access to your applications. Integrate multiple identity providers (e.g., Google, Facebook, etc.) to streamline sign-ups and sign-ins.
25. Azure AD Advanced Security Features
25.1. Azure AD Conditional Access and MFA (Advanced Policies)
Beyond basic MFA enforcement, you can set up more granular Conditional Access policies based on risk levels, network location, or device compliance. This provides an additional layer of security for sensitive resources.
PowerShell Example: Configure Conditional Access Based on Device Compliance
# Create a Conditional Access Policy to require device compliance for accessing critical resources
New-AzureADMSConditionalAccessPolicy -DisplayName "Require Device Compliance for Critical Apps" -State "enabled" -Conditions @{
Applications = @("Office365")
DeviceStates = "Compliant"
} -Actions @{
Grant = "RequireMultiFactorAuthentication"
}
Best Practice: For high-risk resources, configure multi-factor authentication and ensure devices are compliant with your organization's security requirements before granting access.
25.2. Microsoft Defender for Identity Integration with Azure AD
Microsoft Defender for Identity provides a layer of security by detecting advanced threats and anomalies in your Azure AD environment.
Steps for Integration:
PowerShell Example: Enabling Defender for Identity Alerts
# Enable Defender for Identity alerts
Set-MicrosoftDefenderIdentityAlert -Enabled $true -AlertSeverity "High" -AlertType "SuspiciousSignIn"
Best Practice: Enable Microsoft Defender for Identity for advanced threat detection. Set up automated response actions to block suspicious activities (e.g., automatic password reset, blocking sign-in).
25.3. Azure AD Identity Governance
Identity Governance features allow you to have full control over user access and entitlement management. This is crucial for ensuring that users are properly assigned access, and their rights are reviewed periodically.
Access Reviews: Automating the Access Review Process
You can use Access Reviews to ensure that users have the appropriate permissions.
# Create an access review for a specific group to ensure only required users have access
New-AzureADMSAccessReview -DisplayName "Monthly Sales Group Access Review" -Schedule "Monthly" -GroupId "SalesGroupId"
Best Practice: Regularly perform access reviews to ensure users’ access is up-to-date and remove any unnecessary or excessive permissions.
26. Automation and User Lifecycle Management
26.1. Automating User Creation and Group Assignment
You can automate user onboarding and group assignments using Power Automate or Azure Logic Apps, integrated with Azure AD.
Example: Power Automate Flow for Automated User Onboarding
Example PowerShell to Automate User Onboarding
# Automatically create a user and assign them to a group based on job title
$jobTitle = "Developer"
$newUser = New-AzureADUser -UserPrincipalName "newuser@contoso.com" -DisplayName "New Developer" -PasswordProfile @{ ForceChangePasswordNextSignIn = $true; Password = "TempPassword123" }
if ($jobTitle -eq "Developer") {
$group = Get-AzureADGroup -Filter "DisplayName eq 'Developers'"
Add-AzureADGroupMember -ObjectId $group.ObjectId -RefObjectId $newUser.ObjectId
}
Best Practice: Automate the entire user lifecycle, including onboarding and offboarding, to eliminate manual intervention and ensure consistency across the organization.
26.2. Automating User Offboarding and Cleanup
Automating user offboarding (removing access and disabling accounts) ensures that former employees do not retain unauthorized access.
PowerShell Script for Offboarding Users:
# Automatically disable users who have left the company and remove group membership
$users = Get-AzureADUser -All $true | Where-Object { $_.AccountEnabled -eq $false }
foreach ($user in $users) {
# Remove group memberships
$groups = Get-AzureADUserMembership -ObjectId $user.ObjectId
foreach ($group in $groups) {
Remove-AzureADGroupMember -ObjectId $group.ObjectId -MemberId $user.ObjectId
}
# Disable and delete user account
Set-AzureADUser -ObjectId $user.ObjectId -AccountEnabled $false
Remove-AzureADUser -ObjectId $user.ObjectId
}
Best Practice: Automate user offboarding to revoke all access promptly upon termination to prevent security risks.
27. Azure AD API and Integration
27.1. Azure AD Graph API and Microsoft Graph API
Azure AD provides powerful APIs to interact with users, groups, devices, and more.
Example: Use Microsoft Graph API to Create a User
# Example of creating a user using Microsoft Graph API
$accessToken = Get-MicrosoftGraphAccessToken
$uri = "https://graph.microsoft.com/v1.0/users"
$body = @{
accountEnabled = $true
displayName = "John Doe"
