A cloud-based identity and access management service for securing user authentication and resource access
@Prasant Chettri Thanks for reaching out. There is no such requirement of having Intune ODJ connector to be same on AAD connect server. Both services serve different purpose and are independent and should always be consider for a separate server existence if the infrastructure has no restrictions.
AAD connect server already have few dedicated work which consume much resources from the server, giving it extra task of Intune ODJ will only take a toll on its performance if your are having large number of devices. But if this is a small environment, both can be on Same server. For example, I run everything on same server (DC, AAD connect, Intune connector) and it works perfectly fine obviously mine is a very small lab environment,
