Re: LDAP Authentication

*) Check whether you have any iptables rules running with command "iptables -L -n".
*) Check whether your OpenLDAP is listening on port 389 and accepts connection from external network. e.g.

# netstat -ntlp | grep 389
tcp        0      0 0.0.0.0:389             0.0.0.0:*               LISTEN      3184/slapd

NOTE: If it's 0.0.0.0:389, it's fine. if it's '127.0.0.1:389', you have to update parameter 'SLAPD_SERVICES' in /etc/default/slapd:

SLAPD_SERVICES="ldap:/// ldapi:///"

Then use correct LDAP server address, port (389), bind dn and password in your ldap client.
