Importare schema LDAP

In questo esempio si userà l'importo del schema di Pure FTP.

a) Creare il file pureftpd.schema con il seguente contenuto:

#
# pureftpd.schema
#
# Pure-FTPd User LDAP Schema
# See README.LDAP in the Pure-FTPd documentation for more information.

        SUP top AUXILIARY

              FTPDownloadRatio $ FTPUploadBandwidth $ FTPDownloadBandwidth $
              FTPuid $ FTPgid $ FTPHomeDir ) )

b) Copiare il file nelle seguenti cartelle:

/etc/ldap/schema/
/usr/share/univention-ldap/schema/
/var/lib/univention-ldap/local-schema/

c) Aggiungere in /etc/ldap/slapd.conf :

# Indexes for Pure-FTPd LDAP attributes.
index FTPQuotaFiles,FTPQuotaMBytes eq,pres
index FTPUploadRatio,FTPDownloadRatio eq,pres
index FTPUploadBandwidth,FTPDownloadBandwidth eq,pres
index FTPStatus,FTPuid,FTPgid,FTPHomeDir eq,pres

d) Eseguire i seguenti cli:

/usr/sbin/univention-config-registry commit /etc/ldap/slapd.conf
/etc/init.d/slapd crestart

Creare gli attributi

Creare gli attributi secondo lo schema. Cioè. objectClass è PureFTPdUser e gli attributi con le loro caratteristiche sono:

FTPHomeDir con valore string /var/ftp
FTPgid con valore integer 1000
FTPuid con valore integer 1000
FTPStatus con valore string enabled/disabled

Usare il web per creare gli attributi. Andare su LDAP directory. Scegliere dal albero univention-custom attributes. Clicare su add. Andate su Setting: Extended Attribute. Compilare con il nome del attributo le seguenti:

Unique name *
UDM CLI name
Short description *

a) In Module scegliete User.

b) In LDAP Mapping 'LDAP object class *' è PureFTPdUser e gli attributi secondo lista FTPHomeDir o FTPgid o FTPStatus oppure FTPuid. Clicare 'Remove object class if the attribute is removed'. Per ogni attributo si fa lo stesso procedimento.

c) In UMC inserisci 'Tab name' come il nome del attributo se si desidera.

d) In 'Data Type' scegli 'Edit after Creation'. Mettere i valori default come sopra indicato.Esempio.Per FTPuid e FTPgid inserire 1000.

Il valore FTPStatus si puo cambiare nel utente. Se si mette il valore 'disabled', l'utente non puo accedere con FTP.

Config Pure FTP

Questa è la config giusta per l'ambiente 3D. /etc/pure-ftpd/db/ldap.conf
