Azure Active Directory (Azure AD) Connect
Azure Active Directory (Azure AD) Connect is a tool that connects your on-premises identity infrastructure to Microsoft Azure AD. When setting up Azure AD Connect, one of the critical considerations is choosing which objects should be synchronized to Azure AD. By configuring object filters, you can define precisely which objects, such as users, groups, and contacts, are included or excluded from the synchronization process.
Understanding Default and Custom Synchronization Rules
Azure AD Connect comes with a set of default synchronization rules that apply to common scenarios. These rules define which objects are included or excluded based on attributes like location in the directory or the presence of specific attribute values. In some cases, however, you may need to create custom synchronization rules to meet the specific requirements of your organization.
Creating and Customizing Synchronization Rules
To create or customize synchronization rules, you can use the “Synchronization Rules Editor” that is included with Azure AD Connect. This tool provides a graphical interface for creating new rules or editing existing rules.
Filtering by Organizational Units (OUs)
One common method of filtering objects is by organizational unit (OU). You can select which OUs you want to sync to Azure AD.
For example, suppose your Active Directory has the following OUs:
- Employees
- Contractors
- Service Accounts
- Inactive Users
If you only want to synchronize the “Employees” and “Contractors” OUs, you can set up your synchronization rule to include only these two.
Filtering by Attribute-Based Rules
Another method for filtering objects is to use attribute-based rules. You can create rules that include or exclude objects based on the values of specific attributes. This approach is more granular and allows for nuanced control over synchronization.
For instance, you might have a user attribute called “EmployeeType.” You can create a rule that only includes users where “EmployeeType” equals “Full-Time” or “Part-Time,” excluding other types such as “Intern” or “Contractor.”
Object Filtering Best Practices
- Plan your filters: Before you begin configuring your filters, carefully plan which objects should and should not be synchronized. A well-thought-out filtering strategy can prevent unnecessary data from being synchronized and reduce the risk of polluting your Azure AD tenant with unwanted objects.
- Test changes in a staging environment: It’s important to test your synchronization rules in a controlled environment to understand the impact of your filters. Azure AD Connect provides a staging mode that can be used for this purpose.
- Avoid unnecessary exclusions: Be cautious about over-filtering. While it’s possible to exclude a large number of objects, doing so may inadvertently leave out important information or users. Be particularly wary of filtering out system or service accounts required for application integrations.
- Consistency across directories: Ensure that your filtering configuration aligns with the way your on-premises directory and Azure AD are structured. Consistency will reduce confusion and make management easier.
- Regularly review your filters: The needs of your organization may change over time, so it’s a good idea to periodically review your filter configurations to ensure they still align with your current requirements.
Example of Custom Synchronization Rule
| Attribute | Condition | Value | Action |
|---|---|---|---|
| userAccountControl | NOT Bitwise AND | 2 | Exclude |
| department | EQUAL | “HR” | Include |
| employeeType | EQUAL | “Full-Time” | Include |
| employeeType | EQUAL | “Part-Time” | Include |
In this example table, we are setting conditions such that user accounts that are disabled (userAccountControl with Bitwise AND of 2) are excluded, department is “HR” are included, and employeeType is either “Full-Time” or “Part-Time” are also included.
By properly configuring Azure AD Connect object filters, you can ensure that only the necessary objects are synchronized to your Azure AD, thereby streamlining the identity management process and improving overall security and performance in your hybrid environment.
Practice Test with Explanation
True or False: Azure AD Connect allows you to filter which objects are synchronized to Azure AD based on OU, domain, and attribute-based filters.
- (A) True
- (B) False
Answer: A
Explanation: Azure AD Connect allows for filtering by organizational unit (OU), domain, and attributes. This enables selective synchronization of only the objects needed.
Which filtering option in Azure AD Connect allows you to exclude particular synchronization rules without deleting them?
- (A) Domain-based filtering
- (B) OU-based filtering
- (C) Group-based filtering
- (D) Attribute-based filtering
Answer: D
Explanation: Attribute-based filtering can be used to configure exclusions on synchronization rules, thereby preventing specific objects from being synced without deleting the actual rules.
True or False: Once you’ve chosen a filtering configuration during the Azure AD Connect wizard setup, you cannot change the configuration later on.
- (A) True
- (B) False
Answer: B
Explanation: You can change your filtering configuration after the initial setup by rerunning the Azure AD Connect wizard or using PowerShell.
What is the default configuration for object filtering in Azure AD Connect?
- (A) Synchronize all objects
- (B) Synchronize objects from selected domains only
- (C) Synchronize no objects
- (D) Synchronize only users and groups
Answer: A
Explanation: The default configuration of Azure AD Connect is to synchronize all objects from all domains in the directory.
True or False: Azure AD Connect does not support filtering based on group memberships.
- (A) True
- (B) False
Answer: B
Explanation: Azure AD Connect supports group-based filtering, where synchronization can be scoped to the members of a specific group.
In which scenario would you use domain-based filtering in Azure AD Connect?
- (A) To only sync objects from specific domains within your forest
- (B) To exclude specific attributes from synchronization
- (C) To filter out specific users or groups
- (D) To sync only objects with a specific attribute value
Answer: A
Explanation: Domain-based filtering is used when you want to limit the synchronization to objects that reside in specific domains within the forest.
True or False: By default, password hash synchronization is filtered out and must be manually enabled.
- (A) True
- (B) False
Answer: B
Explanation: Password hash synchronization is enabled by default with Azure AD Connect unless you explicitly choose to disable it during setup.
When using attribute-based filtering, which tool do you use to define custom synchronization rules?
- (A) Azure AD Connect wizard
- (B) Azure portal
- (C) Synchronization Rules Editor
- (D) Synchronization Service Manager
Answer: C
Explanation: The Synchronization Rules Editor is the tool used to create or modify custom synchronization rules for attribute-based filtering.
To apply OU-based filtering, which step must be completed in Azure AD Connect?
- (A) Run the Azure AD Connect synchronization service
- (B) Modify the AD FS configuration
- (C) Disable and re-enable synchronization
- (D) Deselect the OUs you want to exclude in the Azure AD Connect wizard
Answer: D
Explanation: Within the Azure AD Connect setup wizard, you can select or deselect the organizational units (OUs) you want to include or exclude from synchronization.
True or False: After implementing filtering in Azure AD Connect, it’s essential to perform a full synchronization to apply the changes.
- (A) True
- (B) False
Answer: A
Explanation: When you change filtering configurations in Azure AD Connect, a full synchronization is required to ensure that the correct objects are synced based on the new filtering setup.
Which synchronization feature in Azure AD Connect should be used if you want to ensure that only user objects from certain departments are synchronized?
- (A) OU-based filtering
- (B) Domain-based filtering
- (C) Group-based filtering
- (D) Attribute-based filtering
Answer: D
Explanation: Attribute-based filtering would allow you to synchronize only user objects with specific attribute values, such as those who have a certain department listed in their AD properties.
True or False: You can set up Azure AD Connect filtering to include only user accounts that are not disabled.
- (A) True
- (B) False
Answer: A
Explanation: By using attribute-based filtering, you can include or exclude user accounts based on their ‘userAccountControl’ attribute, which indicates whether an account is disabled.
