As organizations decide to migrate to cloud SaaS, and particularly Microsoft 365, one of the first steps many take is synchronizing their on-premises directory to Microsoft Azure. This process allows businesses to have the same usernames and passwords in the cloud that exist on-premises, allowing users to have seamless functionality. One of the tools available is a tool called IDfix. It aims to improve directory synchronization and resolve issues with attributes for on-premises users. Developed by Microsoft, it simplifies the tasks of Active Directory Administrators responsible for flawless synchronization.
What is Active Directory?
Active Directory (AD) is the defacto identity and access management solution used in on-premises environments for years. It helps administrators manage and secure network resources. Active Directory Domain Services (AD DS) and Azure Active Directory are essential components, with Azure Active Directory extending directory services to the cloud.
As a note, Microsoft recently renamed Azure Active Directory to Entra ID. So, we are starting to see documentation and naming conventions reflecting this change.
Why Idfix is Important for Directory Synchronization
Organizations typically use a Microsoft tool known as Azure AD Connect for directory synchronization between On-Premises Active Directory and Azure Active Directory. It provides synchronization capabilities, allowing companies to successfully synchronize users between on-premises AD resources to Azure Active Directory.
However, after years of churn and flux with on-premises Active Directory, attributes and other properties of these objects may contain errors, duplicates, etc. While these can be resolved manually, IDfix can automatically scan for and resolve issues with Active Directory objects. It’s crucial for administrators who want to synchronize users successfully without an error message to fix object errors and ensure correct attribute values without hassle.
Features of the Idfix Tool
The Idfix tool offers various functions to assist Active Directory Administrators in achieving perfect directory synchronization. It’s handy for identifying and fixing object errors with suggested values.
Identifying and Fixing Errors
IDfix can spot errors, including invalid characters and duplicate items in attribute values. It’s excellent at finding errors within identity objects in the on-premises Active Directory, providing details on possible synchronization issues.
Easy Installation and Friendly Interface
IDfix is easy to install with basic Internet settings and meets NET Framework requirements. Users can download Idfix and start the installation with the ClickOnce app. The tool provides an intuitive interface for easy navigation and use.
Streamlined Error Fixing Process
Idfix has a streamlined process for fixing errors. It provides suggested values to correct errors once identified. Administrators can view suggestions in the action column and implement changes easily, ensuring successful synchronization and the ability to remediate object errors.
Installing and running the IDfix tool
It’s important to make sure the user account has write access and the domain controller is accessible before running Idfix. However, as we will see below, there is a way to pass along a different user in the tool.
The IDfix tool can be downloaded from the official Microsoft Github site here: https://github.com/microsoft/idfix. It is a ClickOnce app. When you download, simply execute the EXE and click Install.

Here, the IDfix utility is launched and ready to scan our Active Directory environment.
After the IDfix utility launches, click the Query button to scan your Active Directory environment objects. Note, that you must run the tool as a user with permissions to your Active Directory environment.
Under the settings of the IDfix tool, you can specify alternate credentials for connecting to your Active Directory environment.
Once we run the Query function, the Active Directory users will be pulled into the tool. Also, take note of the Actions column. For the actions column, we can choose various actions to perform on the object.
Those options are:
- Edit – The value stored in the attribute will be updated with the correct one
- Remove – The incorrect value stored in the attribute will be removed.
- Complete – This option allows you to confirm that the attributes have the correct value, even if they display an error. It means it won’t be changed after selecting Complete and Apply.
Pay attention to error messages from Idfix as they provide insight into synchronization issues. Following the tool’s recommendations in the action column helps fix errors, helping to make sure you have a successful user synchronization between directory services.
Frequently Asked Questions
How Does Idfix Relate to Azure AD Connect?
Idfix is often used with Azure AD Connect to resolve any issues with AD objects and attributes before synchronization happens.
Can Idfix Handle All the Errors in Active Directory?
There may be some complex or unique errors or edge cases that IDfix can’t handle and instead need manual intervention by Active Directory Administrators.
What Are the Prerequisites for Using Idfix?
Before using Idfix, make sure you run it on a compatible Windows device with Microsoft .NET Framework installed, and the user account that will run Idfix has the necessary write access permissions to make changes to Active Directory.
What Happens After Idfix Identifies Errors?
Once Idfix identifies errors, it provides suggestions in the update and action columns to help administrators decide on the best action to fix these errors.
What Types of Objects Does Idfix Work With?
Idfix works with identity objects within your Active Directory, such as users, groups, and contacts.
Wrapping up
In Active Directory synchronization, Idfix is an essential tool for administrators. It can identify, fix, and resolve errors in the Active Directory before administrators attempt to synchronize the on-premises directory with Azure Active Directory. It helps to make the transition to hybrid identities much smoother and resolve issues beforehand when organizations migrate to Microsoft 365 and implement single sign-on.
