Sync users from specific group in A.D to nextcloud

Hi
I trying to sync security group in Active directory to nextcloud
I did exactly like this link:
https://forum.owncloud.org/viewtopic.php?t=21164
but the nextcloud can’t see users in group

When I am using this query in “window” , I get the full list of users in that group, but same query in nextcloud show nothing.:
memberof=CN=ownCloudUsers,OU=Security_Groups,OU=Contoso,DC=contoso,DC=local

Thanks
Omer.
