LDAP sip show peers

I have a voip compiled from sources and running on Ubuntu 12.04. For authentication it connects to a remote OpenLDAP server provded by Zentyal. Locally, on Zentyal, if I run sip show peers I get all users, however, if I run sip show peers on the remote voip I get nothing.

Am I missing something? My extconfig.conf and res_ldap.conf are as follows:
