Un annuaire LDAP (avec le schéma misc) est déjà en place, nous souhaitons monter un serveur de mail SMTP/IMAPS en s’appuyant sur l’authentification de l’annuaire LDAP :
apt-get install postfix postfix-ldap dovecot-imapd
Postfix
Tout d’abord /etc/postfix/main.cf :
smtpd_banner = $myhostname
biff = no
append_dot_mydomain = no
readme_directory = no
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
myhostname = hostname.zici.fr
myorigin = /etc/mailname
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = /usr/lib/dovecot/deliver
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
luser_relay =
alias_maps = hash:/etc/aliases
virtual_mailbox_domains = zici.fr, mercereau.info, liencontrelien.zici.fr
virtual_alias_maps = hash:/www/zici/emailPoubelle/virtual
dovecot_destination_recipient_limit = 1
virtual_transport = dovecot
mailbox_transport = dovecot
dovecot_destination_recipient_limit = 1
Dans le fichier master.cf il suffit de rajouter la ligne suivante à la fin du fichier:
# Dovecot LDA
dovecot unix - n n - - pipe flags=DRhu user=vmail:mail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} -d ${user}
Dovecot
Il n’y a que 2 fichiers de conf, d’abord, /etc/dovecot/dovecot.conf
protocols = imap imaps
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/var/mail/%n
mail_uid = 500
mail_gid = 8
mail_privileged_group = mail
protocol imap {
imap_client_workarounds = outlook-idle
}
protocol pop3 {
pop3_uidl_format = %08Xu%08Xv
}
protocol managesieve {
}
protocol lda {
postmaster_address = postmaster@zici.fr
auth_socket_path = /var/run/dovecot/auth-master
}
auth default {
mechanisms = plain login
passdb pam {
}
passdb ldap {
args = /etc/dovecot/dovecot-ldap.conf
}
userdb ldap {
args = /etc/dovecot/dovecot-ldap.conf
}
user = root
socket listen {
master {
path = /var/run/dovecot/auth-master
mode = 0600
user = vmail
group = mail
}
}
}
dict {
}
plugin {
}
et enfin /etc/dovecot/dovecot-ldap.conf
hosts = 127.0.0.1
auth_bind = yes
ldap_version = 3
base = ou=Utilisateur,dc=zici,dc=fr
user_attrs = uidNumber=500,gidNumber=8
user_filter = (&(objectClass=posixAccount)(cn=%n))
pass_filter = (&(objectClass=posixAccount)(cn=%n))
default_pass_scheme = SSHA
Astuce pour tester les filtres utiliser la commande
ldapsearch -x -h localhost -b "ou=Utilisateur,dc=zici,dc=fr" '(&(objectClass=posixAccount)(cn=Utilisateur))'
