As much as Immy pulling AD information from Azure AD where that is available is great, we do have many clients that are either not sync’d for various reasons or do not use AAD at all (eg. Google). In those scenarios, if Immy could populate People information from connected domain controllers directly that would be great, as we’re missing out on some of the key functionality of Immy without that.
We just create an azure tenant and run azure ad sync. Doesn’t cost anything but about 30 minutes of time once you get the process down. Then, you are also already set up for any kind of migrations or MS licensing with SSO as well.
