OneIM 8.1.4 Synchronization Editor "Scope" auto update

Hello,

I have a question regarding the Scope functionning in the Synchronization Editor.


After created the Active Directory connector, we've set a Scope for the synchronization by activating the needed OrganizationalUnits that we can see in the hierarchy(a blue buttons selection)
The problem is, this scope (a blue selection) has been automatically updated after we created a new OrganizationalUnit in the target system.
I'm not sure this is a normal functionning. What we need is to be sure that only the selected OrganizationalUnit take part in the synchronization, whatever the changes take place in the target. In other words, if there is a new OrganizationalUnit created in the AD, we dont want it to be automatically included in our scope.

Is there some configuration parameter for that?

Many thanks
