User's Group Membership problem with enterprise domain

Hi

I have some problems synchronizing Active Directory in LiveCycle ES 8.0.1.
I'm able to import the users and groups from an active directory to a enterprise domain... but the asociation user to group is not keeped.

The problem could be why the DN of users is different to the DN of the group?

the DN users is something like this:

OU=CED,OU=CDC Utent,DC=house,DC=lan

and the DN of the group:

DC=house,DC=lan

Thanks
