[Postfix-es] Error de conexion con server LDAP

[Alejandro Kurchis]

Buenos dias, soy nuevo en la lista y tambien en Postfix, pero me
interesa mucho este servidor. Lo estoy tratando de configurar con un
server LDAP para autenticar usuarios de mail, el server LDAP funciona
bien (slapd en el port tcp/389)y ambos servicios corren en la misma PC.

Mi /etc/hosts resuelve bien a localhost y a la IP de la interface LAN,
poniendole como alias ademas del nombre del host, el dominio del mismo
(mi_casa.com).

Siendo root, intento mandar un mail a un alias de mi sistema, y me da
error de conexion con el server LDAP /nss_ldap: could not connect to any
LDAP server as (null) - Can't contact LDAP serv), y el contenido del
/var/log/mail.log es el siguiente:
