Active Directory schema accepts custom attributes. Based on business requirements some time organizations will have to introduce custom attributes to object classes. On most occasions, it is related to application integration requirements with Active Directory. In one of my previous blog posts, I explained how we can add a custom attribute to Active Directory. You can access it using https://www.rebeladmin.com/2017/11/step-step-guide-create-custom-active-directory-attributes/
In a hybrid setup, Azure AD Connect can sync attribute values from on-premise Active Directory to Azure AD (https://docs.microsoft.com/en-us/azure/active-directory/hybrid/reference-connect-sync-attributes-synchronized). Apart from default attributes, sometimes there can be business requirements to sync custom Active Directory attributes to Azure AD. We can sync these custom attributes to Azure AD by using the Azure AD Connect “Directory extension attribute sync” feature.
In this demo, I am going to demonstrate how to sync the custom Active Directory attribute to Azure AD. To simplify the process, I already installed Azure AD Connect and configure it to sync. I also created a custom AD attribute called “nINumber” and added it to the user class.

Let’s go ahead and see how we can configure Azure AD Connect to sync custom attributes. [Continue reading] about Step-by-Step Guide: How to sync Custom Active Directory Attributes to Azure AD?
