Настройка Postfix для аутентификации пользователей в Active Directory.

Настройка

Создание пользователя в Active Directory

samba-tool user add -W Users vmail
samba-tool user setexpiry vmail --noexpiry

Настройка Postfix

apt-get install postfix-ldap

Изменение файлов

В каталоге /etc/postfix изменяем файлы для домена test.alt:

main.cf

# Global Postfix configuration file.  This file lists only a small subset
# of all parameters.  For the syntax, and for a complete parameter list,
# see the postconf(5) manual page.  For a commented and more complete
# version of this file see /etc/postfix/main.cf.dist

transport

test.alt        dovecot

Запуск postmap

postmap hash:/etc/postfix/transport

Тестируем работу

Проверка пользователя почты petrov:

# postmap -q petrov@test.alt ldap:/etc/postfix/ad_virtual_mailbox_maps.cf
test.alt/petrov/Maildir/

Проверка входа:

# postmap -q petrov@test.alt ldap:/etc/postfix/ad_sender_login_maps.cf
petrov@test.alt

Проверка общего адреса e-mail:

# samba-tool group add --mail-address=sales@test.alt Sales
Added group Sales
# samba-tool group addmembers Sales ivanov,petrov
Added members to group Sales
# postmap -q sales@test.alt ldap:/etc/postfix/ad_virtual_group_maps.cf
ivanov@test.alt,ivanov@test.alt,petrov@test.alt,petrov@test.alt

Настройка Dovecot

Устанавливаем Dovecot:

apt-get install dovecot

Создаём файл /etc/dovecot/dovecot-ldap.conf.ext

hosts           = test.alt:389
ldap_version    = 3
auth_bind       = yes
dn              = cn=vmail,cn=Users,dc=test,dc=alt
dnpass          = Pa$$word
base            = cn=Users,dc=example,dc=com
scope           = subtree
deref           = never
user_filter     = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl=514)))
pass_filter     = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl=514)))
pass_attrs      = userPassword=password
default_pass_scheme = CRYPT
user_attrs      = =home=/var/vmail/vmail1/%Ld/%Ln/Maildir/,=mail=maildir:/var/vmail/vmail1/%Ld/%Ln/Maildir/

Перезапускаем службу dovecot и включаем её в автозапуск:

chkconfig dovecot on
service dovecot restart

Проверяем вход

# telnet localhost 143
