Display members of Active Directory groups

I'm trying to display the members of the groups I can select from LDAP (Ms Active Directory in my company)
I can see the groups with no problems, but in the braket I cannot see any member. the same if I click ib the gruop name, I obtain an empty list.
I tried quite all, but this is something I cannot solve. Can anyone help me?
In attached my group.ldap.proprietis file

1. Configuration file for standard ldap server
   groups.ldap.context.factory = com.sun.jndi.ldap.LdapCtxFactory
   groups.ldap.url = ldap://10.148.2.29:389/
   groups.ldap.authentification.mode = simple
   groups.ldap.public.bind.dn = cn=wpsbind,ou=portal,ou=application,dc=europe,dc=odcorp,dc=net
   groups.ldap.public.bind.password = wpsbind

1. attribute holding the group name
   groups.ldap.search.attribute = cn

1. base dn search
   groups.ldap.search.name = OU=Portal,OU=Application,DC=europe,DC=odcorp,DC=net
   groups.ldap.search.countlimit = 100
   groups.ldap.search.objectclass = group
   groups.ldap.members.attribute = member

1. ------- objectclasses and member attributes ------------
   groups.ldap.dynamic.search.objectclass = memberOf
   groups.ldap.dynamic.members.attribute = cn

1. ------- originale ------
2. groups.ldap.search.objectclass = groupOfUniqueNames
3. groups.ldap.members.attribute = uniqueMember
4. groups.ldap.dynamic.search.objectclass = groupOfURLs
5. groups.ldap.dynamic.members.attribute = memberurl

1. if set to false, group members will not be preloaded and members will not appear in engines
   groups.ldap.preload = true

1. the following defines the attributes to use for wildcard search such as *=test
   groups.ldap.search.wildcards.attributes = cn, sAMAccountName

1. Map attribute, that indicate which LDAP attribute to map to Jahia standard properties
2. Make sure you comment out the ones you are not using, especially if the LDAP
3. repository contains same names attributes. If you don't searching goups will
4. most probably not work correctly.
   groups.ldap.groupname.attribute.map = cn
   groups.ldap.description.attribute.map = sAMAccountName
