|
|
<p>iRedMail configures Roundcube webmail to store last password change date while
|
|
user changed password. For MySQL/MariaDB/PostgreSQL backends, it's stored in
|
|
SQL database <code>vmail</code>, column <code>mailbox.passwordlastchange</code>. For LDAP backends,
|
|
it's stored in LDAP attribute <code>shadowLastChange</code> of user account. If user
|
|
didn't change password before, or user account is newly created, the password
|
|
last change date will be set to <code>0000-00-00 00:00:00</code>.</p>
|
|
<p>iRedAPD has plugin to force mail users to change password before sending email:</p>
|
|
<ul>
|
|
<li><code>sql_force_change_password</code>: for SQL backends (MySQL, MariaDB and
|
|
PostgreSQL).</li>
|
|
<li><code>ldap_force_change_password</code>: for LDAP backends (OpenLDAP and OpenBSD
|
|
built-in LDAP server <code>ldapd(8)</code>).</li>
|
|
</ul>
|
|
<p>When user trying to send an email, iRedAPD will invoke this plugin to
|
|
check password last change date stored in SQL/LDAP and compare
|
|
it with current date. if password last change date is longer than specified
|
|
days, this plugin rejects smtp session with specified message.</p>
|
|
<h2 id="how-to-enable-iredapd-plugin">How to enable iRedAPD plugin</h2>
|
|
<p>To enable this plugin, please list the plugin name in iRedAPD config file
|
|
<code>/opt/iredapd/settings.py</code>, variable <code>plugins =</code>. For example:</p>
|
|
<pre><code class="language-python"># For SQL backends
|
|
plugins = [..., 'sql_force_change_password']
|
|
|
|
# For LDAP backends:
|
|
plugins = [..., 'ldap_force_change_password']
|
|
</code></pre>
|
|
<p>There're three optional settings pre-defined in <code>/opt/iredapd/libs/default_settings.py</code>,
|
|
if you want to change them, please copy the parameter names and set proper values
|
|
in <code>/opt/iredapd/settings.py</code>:</p>
|
|
<pre><code># Force to change password in certain days.
|
|
CHANGE_PASSWORD_DAYS = 90
|
|
|
|
# Reject reason.
|
|
# It's recommended to add URL of the web applications which user can login
|
|
# to change password in this message. e.g. Roundcube webmail, iRedAdmin-Pro.
|
|
CHANGE_PASSWORD_MESSAGE = 'Password expired or never changed, please change your password in webmail before sending email'
|
|
|
|
# Allow certain users or domains to never change password.
|
|
# sample values: ['user@example.com', 'domain.com']
|
|
CHANGE_PASSWORD_NEVER_EXPIRE_USERS = []
|
|
</code></pre>
|
|
<p>Restarting <code>iredapd</code> service is required after changed <code>/opt/iredapd/settings.py</code>.</p>
|
|
<h2 id="roundcube-plugin-force_password_change">Roundcube plugin: <code>force_password_change</code></h2>
|
|
