Adesso dobbiamo copiare in <tt>/etc/ldap/schema</tt> lo schema LDAP necessario per SAMBA.
Adesso dobbiamo recuperare gli schemi mancanti, che aggiungeremo poi alla configurazione di LDAP, e copiare in <tt>/etc/ldap/schema</tt> lo schema LDAP necessario per SAMBA.

# wget http://www.pepinet.com/download/samba/hdb.schema -P /etc/ldap/schema/

Ora occorre modificare il file di configurazione di slapd (<tt>/etc/ldap/slapd.conf</tt>) aggiungendo nella sezione <tt>Schema and objectClass definitions</tt> lo schema per samba:
Ora occorre modificare pesantemente il file di configurazione di slapd (<tt>/etc/ldap/slapd.conf</tt>) aggiungendo diverse sezioni. Il contenuto del file dovrebbe essere il seguente:<br/>
<pre>
include /etc/ldap/schema/samba.schema
</pre>
Nella sezione <tt>Indexing options</tt> aggiungere una serie di indicizzazioni che ottimizzeranno le interogazioni per l'utilizzo del server SAMBA:
<pre>
index objectClass eq,pres
index uid,uidNumber,gidNumber,memberUid eq,pres
index ou,cn,mail,surname,givenname eq,pres,sub
index loginShell                        eq,pres
index displayName                      pres,sub,eq
index nisMapName,nisMapEntry            eq,pres,sub
index sambaSID eq
index sambaPrimaryGroupSID eq
index sambaDomainName eq
index sambaGroupType eq
index sambaSIDList eq
index uniqueMember eq
index default                          sub
</pre>
Bisogna consentire agli utenti di cambiare non solo la propria password LDAP, ma anche le password di SAMBA e contemporaneamente proteggere tali informazioni da un accesso pubblico sostituendo la riga:
<pre>
access to attribute=userPassword
</pre>
con:
<pre>
access to attrs=userPassword,sambaNTPassword,sambaLMPassword,sambaPwdMustChange,sambaPwdLastSet
</pre>
Infine aggiungere le informazioni per l'autenticazione:
<pre>
rootdn          "cn=admin,dc=dominio,dc=local"
rootpw          {MD5}Qhz9FD5FDD9YFKBJVAngcw==
</pre>
Il contenuto del file dovrebbe essere il seguente:<br/>
'''/etc/ldap/sldap.conf''':
'''/etc/ldap/sldap.conf''':
