Hello Laurent,
Kindly elaborate the user migration process. You may need to do this in two stages iteratively. Make sure the below before migrating the Windows AD users using UMT
Stage -1
- Configure and Enable the AD Authentication in target BI4.0 system.
- Update only the AD Groups and avoid importing Users.
- Make sure all the AD groups are imported with no users assigned under them
Stage-2
Select only Users and Groups in UMT. Once the dependent object list is created exclude the Users and Groups and select the below
- User Favorites Folder
- Personal Categories
- User Inboxes
Try this and let me know how it goes.
Regards,
Mani
