Asterisk & LDAP

I know where I can find information or can guide me on how to integrate asterisk to LDAP. Asterisk I have it compiled with the LDAP module and LDAP and the asterisk integregre scheme, but I is working on login.

My system is running with:
Ubuntu 10.04LTS 64b + Samba PDC + LDAP
asterisk-1.8.10.1
freepbx-2-10.0

best regards
