Found finaly the "AD-Import-Wizard-Button" (System>Authentication>Authentication Servers at the end of the Row...) and got my Add-Groups imported in the Copernicus-Groups.
But the Groups were empty on Copernicus.
In the AD-Group the Users were still there.
The Base-DN was DC=domain,DC=local.
The User for the Import was the Domain-Admin.
So everything should be visible...
Has anyone experienced something similar, have I made a mistake somewhere?.
