i want to create a ad connection in user profile service application, which sync specific users. These users are members of a group. When i check this group in the "AD Container" and start a full sync, none of the group members is synced. Question: How can i sync AD users without checking them directly in the "AD Container"?
You need to select the OU, not the group. You can use exclusion filters to define who not to select. See this article below by Spence Harbar.
