<h1>LDAP Authentication</h1>
<h2 id="introduction"><a class="toclink" href="#introduction">Introduction</a></h2>
<p>Getting started with ldap and this mailserver we need to take 3 parts in account:</p>
<ul>
<li><code>postfix</code> for incoming &amp; outgoing email</li>
<li><code>dovecot</code> for accessing mailboxes</li>
<li><code>saslauthd</code> for SMTP authentication (this can also be delegated to dovecot)</li>
</ul>
<h2 id="variables-to-control-provisioning-by-the-container"><a class="toclink" href="#variables-to-control-provisioning-by-the-container">Variables to Control Provisioning by the Container</a></h2>
<p>Have a look at <a href="../../environment/">the ENV page</a> for information on the default values.</p>
<h3 id="ldap_query_filter_"><a class="toclink" href="#ldap_query_filter_"><code>LDAP_QUERY_FILTER_*</code></a></h3>
<p>Those variables contain the LDAP lookup filters for postfix, using <code>%s</code> as the placeholder for the domain or email address in question. This means that...</p>
<ul>
<li>...for incoming email, the domain must return an entry for the <code>DOMAIN</code> filter (see <a href="http://www.postfix.org/postconf.5.html#virtual_alias_domains"><code>virtual_alias_domains</code></a>).</li>
<li>...for incoming email, the inboxes which receive the email are chosen by the <code>USER</code>, <code>ALIAS</code> and <code>GROUP</code> filters.<ul>
<li>The <code>USER</code> filter specifies personal mailboxes, for which only one should exist per address, for example <code>(mail=%s)</code> (also see <a href="http://www.postfix.org/postconf.5.html#virtual_mailbox_maps"><code>virtual_mailbox_maps</code></a>)</li>
<li>The <code>ALIAS</code> filter specifies aliases for mailboxes, using <a href="http://www.postfix.org/postconf.5.html#virtual_alias_maps"><code>virtual_alias_maps</code></a>, for example <code>(mailAlias=%s)</code></li>
<li>The <code>GROUP</code> filter specifies the personal mailboxes in a group (for emails that multiple people shall receive), using <a href="http://www.postfix.org/postconf.5.html#virtual_alias_maps"><code>virtual_alias_maps</code></a>, for example <code>(mailGroupMember=%s)</code></li>
<li>Technically, there is no difference between <code>ALIAS</code> and <code>GROUP</code>, but ideally you should use <code>ALIAS</code> for personal aliases for a singular person (like <code>ceo@example.org</code>) and <code>GROUP</code> for multiple people (like <code>hr@example.org</code>).</li>
</ul>
</li>
<li>...for outgoing email, the sender address is put through the <code>SENDERS</code> filter, and only if the authenticated user is one of the returned entries, the email can be sent.<ul>
<li>This only applies if <code>SPOOF_PROTECTION=1</code>.</li>
<li>If the <code>SENDERS</code> filter is missing, the <code>USER</code>, <code>ALIAS</code> and <code>GROUP</code> filters will be used in in a disjunction (OR).</li>
<li>To for example allow users from the <code>admin</code> group to spoof any sender email address, and to force everyone else to only use their personal mailbox address for outgoing email, you can use something like this: <code>(|(memberOf=cn=admin,*)(mail=%s))</code></li>
</ul>
</li>
</ul>
<details class="example" open="open"><summary>Example</summary><p>A really simple <code>LDAP_QUERY_FILTER</code> configuration, using only the <em>user filter</em> and allowing only <code>admin@*</code> to spoof any sender addresses.</p>

<h3 id="dovecot__filter-dovecot__attrs"><a class="toclink" href="#dovecot__filter-dovecot__attrs"><code>DOVECOT_*_FILTER</code> &amp; <code>DOVECOT_*_ATTRS</code></a></h3>
<p>These variables specify the LDAP filters that dovecot uses to determine if a user can log in to their IMAP account, and which mailbox is responsible to receive email for a specific postfix user.</p>
<p>This is split into the following two lookups, both using <code>%u</code> as the placeholder for the full login name (<a href="https://doc.dovecot.org/configuration_manual/config_file/config_variables/">see dovecot documentation for a full list of placeholders</a>). Usually you only need to set <code>DOVECOT_USER_FILTER</code>, in which case it will be used for both filters.</p>
<ul>
<li><code>DOVECOT_USER_FILTER</code> is used to get the account details (uid, gid, home directory, quota, ...) of a user.</li>
<li><code>DOVECOT_PASS_FILTER</code> is used to get the password information of the user, and is in pretty much all cases identical to <code>DOVECOT_USER_FILTER</code> (which is the default behaviour if left away).</li>
</ul>
<p>If your directory doesn't have the <a href="https://github.com/variablenix/ldap-mail-schema/blob/master/postfix-book.schema">postfix-book schema</a> installed, then you must change the internal attribute handling for dovecot. For this you have to change the <code>pass_attr</code> and the <code>user_attr</code> mapping, as shown in the example below:</p>
<div class="highlight"><pre><span></span><code><span class="p p-Indicator">-</span> <span class="l l-Scalar l-Scalar-Plain">DOVECOT_PASS_ATTRS=&lt;YOUR_USER_IDENTIFIER_ATTRIBUTE&gt;=user,&lt;YOUR_USER_PASSWORD_ATTRIBUTE&gt;=password</span>
<span class="p p-Indicator">-</span> <span class="l l-Scalar l-Scalar-Plain">DOVECOT_USER_ATTRS=&lt;YOUR_USER_HOME_DIRECTORY_ATTRIBUTE&gt;=home,&lt;YOUR_USER_MAILSTORE_ATTRIBUTE&gt;=mail,&lt;YOUR_USER_MAIL_UID_ATTRIBUTE&gt;=uid,&lt;YOUR_USER_MAIL_GID_ATTRIBUTE&gt;=gid</span>
</code></pre></div>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>For <code>DOVECOT_*_ATTRS</code>, you can replace <code>ldapAttr=dovecotAttr</code> with <code>=dovecotAttr=%{ldap:ldapAttr}</code> for more flexibility, like for example <code>=home=/var/mail/%{ldap:uid}</code> or just <code>=uid=5000</code>.</p>
<p>A list of dovecot attributes can be found <a href="https://doc.dovecot.org/configuration_manual/authentication/user_databases_userdb/#authentication-user-database">in the dovecot documentation</a>.</p>

<p>The LDAP server configuration for dovecot will be taken mostly from postfix, other options can be found in <a href="../../environment/">the environment section in the docs</a>.</p>
<h3 id="dovecot_auth_bind"><a class="toclink" href="#dovecot_auth_bind"><code>DOVECOT_AUTH_BIND</code></a></h3>
<p>Set this to <code>yes</code> to enable authentication binds (<a href="https://wiki.dovecot.org/AuthDatabase/LDAP/AuthBinds">more details in the dovecot documentation</a>). Currently, only DN lookup is supported without further changes to the configuration files, so this is only useful when you want to bind as a readonly user without the permission to read passwords.</p>
<h3 id="saslauthd_ldap_filter"><a class="toclink" href="#saslauthd_ldap_filter"><code>SASLAUTHD_LDAP_FILTER</code></a></h3>
<p>This filter is used for <code>saslauthd</code>, which is called by postfix when someone is authenticating through SMTP (assuming that <code>SASLAUTHD_MECHANISMS=ldap</code> is being used). Note that you'll need to set up the LDAP server for saslauthd seperately from postfix.</p>
<p>The filter variables are explained in detail <a href="https://github.com/winlibs/cyrus-sasl/blob/master/saslauthd/LDAP_SASLAUTHD#L121">in the <code>LDAP_SASLAUTHD</code> file</a>, but unfortunately, this method doesn't really support domains right now - that means that <code>%U</code> is the only token that makes sense in this variable.</p>
<div class="admonition note">
<p class="admonition-title">When to use this and how to avoid it</p>
<p>Using a separate filter for SMTP authentication allows you to for example allow <code>noreply@example.org</code> to send email, but not log in to IMAP or receive email: <code>(&amp;(mail=%U@example.org)(|(memberOf=cn=email,*)(mail=noreply@example.org)))</code></p>
<p>If you don't want to use a separate filter for SMTP authentication, you can set <code>SASLAUTHD_MECHANISMS=rimap</code> and <code>SASLAUTHD_MECH_OPTIONS=127.0.0.1</code> to authenticate against dovecot instead - this means that the <code>DOVECOT_USER_FILTER</code> and <code>DOVECOT_PASS_FILTER</code> will be used for SMTP authentication as well.</p>

<p>To enable LDAPS, all you need to do is to add the protocol to <code>LDAP_SERVER_HOST</code>, for example <code>ldaps://example.org:636</code>.</p>
<p>To enable LDAP over StartTLS (on port 389), you need to set the following environment variables instead (the <strong>protocol must not be <code>ldaps://</code></strong> in this case!):</p>
