Recently I deployed Azure AD Connect server and I notice there are lots of updates and changes made to the latest version of Azure AD Connect application.
The latest version of Azure AD Connect is 2.0. There are few conditions required to follow before setting up the Azure AD Connect application to be running smoothly.
Now there is a new requirement for the service account that is assign for Azure AD Connect application purpose only, the service account must be a member of Administrators group in your local Active Directory. Without this permission, you will faced the synchronization status shows as “completed-with-error” and “permission-denied-access“. You will have trouble in terms of password synchronization.
To further view of what’s new with the version 2.0, you may refer to the references below.
