Cannot synchronize users with Active Directory

Hi,
I am trying to synchronize the users of an Active Directory group with a jmix application (1.4) but I am getting the following error, while this group contains several users:

java.lang.IllegalArgumentException:
No users found in the group: OU=12-Impersonal Users & Groups,OU=Company Users,OU=Group,DC=etae,DC=com
java.lang.IllegalArgumentException: No users found in the group: OU=12-Impersonal Users & Groups,OU=Company Users,OU=Group,DC=etae,DC=com
