As far as I know, two things will block access to an ldap server.
1- Either the firewall is not allowing traffic in on port 389 . This you 
can check with iptables -nvL. You should see a line ACCEPTing packets 
from whoever should be able to query the ldap server. (I'm not sure what 
you mean by "dropped the firewall..." ?)
2- Access limited by "access" rules in your slapd.conf file 
(/etc/openldap/slapd.conf). The default, if there are no access rules, 
is to allow everyone read access, and only the root user to write.
