Problem with Group Mapping (return 0 Members)

I am using 3.2.2 version of Wildfire and have following problem.

The Openldap is the base of users standard in my work, and for User Mapping I have success to see the users, but when I try to Group Mapping, not obtain result (it always returns for me 0 members).

My Group Field is ou (organizationalUnit)

My Member Field is uid

My Description Field is displayName (but that is indifferent for me)

I already tried change Posix Mode, I tried use search filters (Group Filter), per example: (ou=Support)… or (&(ou=Support)(uid=)) … and a lot of other alternatives… still thus it did not work… the groups are not populated…

Somebody can help me?
