Abilitazione del modulo cambio password in Horde per Postfixadmin

• Verificare di aver installato il modulo passwd

sudo /var/www/horde/pear/pear -c /var/www/horde/pear.conf install -a -B horde/passwd

• Creare il file di configurazione custom, copiando la sezione template da backends.php

sudoedit /var/www/horde/passwd/config/backends.local.php

<?php
// This is an example configuration for Postfix.admin 2.3.
// Set the 'password_policy' section as you wish.
// In most installations you probably only need to change the
// hostspec and/or  password fields.
$backends['postfixadmin'] = array(
    'disabled' => false,
    'name' => 'Postfix Admin server',
    'driver' => 'Sql',
    'policy' => array(
        'minLength' => 8,
        'maxLength' => 20,
        'minNumeric' => 1,
    ),
    'params' => array(
        'phptype' => 'mysql',
        'hostspec' => 'localhost',
        'username' => 'postfixadmin',
        'password' => 'SECRETPASSWORD',
        'encryption' => 'crypt-md5',
        'database' => 'postfixadmin',
        'table' => 'mailbox',
        'user_col' => 'username',
        'pass_col' => 'password',
        'show_encryption' => false,
        // The following two settings allow you to specify custom queries for
        // lookup and modify functions if special functions need to be
        // performed.  In places where a username or a password needs to be
        // used, refer to this placeholder reference:
        //    %d -> gets substituted with the domain
        //    %u -> gets substituted with the user
        //    %U -> gets substituted with the user without a domain part
        //    %p -> gets substituted with the plaintext password
        //    %e -> gets substituted with the encrypted password
        //
        'query_lookup' => 'SELECT password FROM mailbox WHERE username = %u and active = 1',
        'query_modify' => 'UPDATE mailbox SET password = %e WHERE username = %u'
    ),
);
