CQ 5.5 & LDAP Conf

I try to configure ldap to only autocreate groups with a specific filter, this doesn't work. Does anyone have such a configuration in place?

Here's what I have :

    groupMembershipAttribute="member"
    autocreate="create"
    autocreate.path="splitdn"
    autocreate.user.cn="rep:fullname"
    autocreate.user.mail="profile/email"
    autocreate.user.sn="profile/familyName"
    autocreate.user.givenName="profile/givenName"
    autocreate.group.cn="rep:fullname"
    autocreate.group.mail="profile/email"
    autocreate.group.description="profile/aboutMe"
    cache.expiration="30000"
    cache.maxsize="1000"
    userFilter="(objectClass=person)"
    groupFilter="(&(ObjectClass=group)(cn=*AEM*))"

I use Active Directory.

I actually do not want AEM to create all groups users are member of but only the ones containing AEM.

groupFilter="(ObjectClass=group)" creates all AD groups within AEM the user is member of.
