LDAP groups and profiles

I have RADIUS running with multiple realms and multiple LDAP back ends that stores all my user attributes. I am trying to apply different user profiles to different groups. What I did was setup the profile in the USERS file, add the group attributes to the ldap config file, and on the user's LDAP account I added the attribute radiusGroupName with the value "residential_profile",  but I can't seem to get it to work correctly. It doesn't seem to query the correct backend. I am sure that I have something wrong but I am not sure what I looked at rlm_ldap and searched the archive list but haven't been able to find anything any help would be appreciated.

This is what my configuration files look like;


DEFAULT Ldap-Group == residential_profile
        Service-Type = Framed-User,
        Framed-Protocol = PPP,
        Cisco-AVPair += "ip:inacl#100=permit tcp any x.x.x.x eq 25",
        Cisco-AVPair += "ip:inacl#200=deny tcp any any eq 25",
        Cisco-AVPair += "ip:inacl#300=permit ip any any",
        Fall-Through = No

ldap ldap2.REALM-2.ca {
        basedn = "ou=radius,o=REALM-2.ca,dc=container,dc=ca"
        filter = "(&(uid=%{%{Stripped-User-Name}:-%{User-Name}})(objectclass=posixAccount)(cn=true))"

ldap ldap1.REALM-1.ca {

       basedn = "ou=radius,o=REALM-1.ca,dc=container,dc=ca"
        filter = "(&(uid=%{%{Stripped-User-Name}:-%{User-Name}})(objectclass=posixAccount)(cn=true))"
        groupname_attribute = cn
        groupmembership_filter = "(|(&(objectClass=GroupOfNames)(member=%{control:Ldap-UserDn}))(&(objectClass=GroupOfUniqueNames)(uniquemember=%{control:Ldap-UserDn})))"
        groupmembership_attribute = radiusGroupName

Output from radius -X
