Titolo: problema con OpenLDAP: ldap_bind: Invalid credentials (49)

Come suggeritomi ripropongo qui il mio quesito, postato inizialmente su it.comp.os.linux.debian
 
Ho un grosso problema con OpenLDAP: non funziona!
Ho una distribuzione Debian Wheezy e ho installato OpenLDAP:
apt-get install slapd ldap-utils
 
pero' a quanto vedo non esiste proprio il file di configurazione in /etc/ldap
L'UNICO che ho trovato in tutto il sistema e' in
/usr/share/slapd
ed e' questo:
=======================
# This is the main slapd configuration file. See slapd.conf(5) for more
# info on the configuration options.

=========================================
inoltre non esiste da nessuna parte neppure un file ldap.conf, neppure in /etc
 
Quando faccio una qualche prova con:
 
ldapsearch -x -D "cn=admin, dc=example" -W
a qualunque password metto mi risponde sempre:
ldap_bind: Invalid credentials (49)
 
Ho provato anche a disinstallare e reinstallare piu' volte i pacchetti, ma fa sempre lo stesso.
Inoltre ho provato a riconfigurare il server con:
dpkg-reconfigure slapd
ho risposto alle varie domande, ma il file di configurazione (sempre in /usr/share/slapd)  non sembra essere mai cambiato.
Qualcuno puo' aiutarmi?
Grazie. 

 /usr/share/slapd
 
Devi evidentemente configurarlo dopo averlo installato:
 
https://wiki.debian.org/LDAP/OpenLDAPSetup
 
 
In particolare: 
https://wiki.debian.org/LDAP/OpenLDAPSetup#Missing_slapd.conf.3F
 
 

 /etc/ldap
 
E` normale, OpenLDAP ha cambiato sistema di gestione della configurazione 
dalla 2.4 in poi, passando dal file slapd.conf al sistema cn=config . In 
teoria, dovresti poter riconfigurare tutto con debconf (anche se puoi usare 
un file slapd.conf come template), in pratica ti consiglio di lasciare 
perdere OpenLDAP e di passare a qualcosa di piu` evoluto (se puoi, 389-ds e` 
presente solo in sid, e OpenDJ potrebbe non piacerti a causa delle 
dipendenze)
