<h1 id="synchronising-from-freeipa"><a class="header" href="#synchronising-from-freeipa">Synchronising from FreeIPA</a></h1>
<p>FreeIPA is a popular opensource LDAP and Kerberos provider, aiming to be &quot;Active Directory&quot; for
Linux.</p>
<p>Kanidm is able to synchronise from FreeIPA for the purposes of coexistence or migration.</p>
<h2 id="installing-the-freeipa-sync-tool"><a class="header" href="#installing-the-freeipa-sync-tool">Installing the FreeIPA Sync Tool</a></h2>
<p>See <a href="../installing_client_tools.html">installing the client tools</a>.</p>
<h2 id="configure-the-freeipa-sync-tool"><a class="header" href="#configure-the-freeipa-sync-tool">Configure the FreeIPA Sync Tool</a></h2>
<p>The sync tool is a bridge between FreeIPA and Kanidm, meaning that the tool must be configured to
communicate to both sides.</p>
<p>Like other components of Kanidm, the FreeIPA sync tool will read your /etc/kanidm/config if present
to understand how to connect to Kanidm.</p>
<p>The sync tool specific components are configured in it's own configuration file.</p>
<pre><code>
# The sync account token as generated by &quot;system sync generate-token&quot;.
sync_token = &quot;eyJhb...&quot;
# A cron-like expression of when to run when in scheduled mode. The format is:
# sec min hour day of month month day of week year
#
# The default of this value is &quot;0 */5 * * * * *&quot; which means &quot;run every 5 minutes&quot;.
# schedule = &quot;&quot;
# If you want to monitor the status of the scheduled sync tool (you should)
# then you can set a bind address here.
#
# If not set, defaults to no status listener.
# status_bind = &quot;&quot;
# The LDAP URI to FreeIPA. This MUST be LDAPS. You should connect to a unique single
# server in the IPA topology rather than via a load balancer or dns srv records. This
# is to prevent replication conflicts and issues due to how 389-ds content sync works.
ipa_uri = &quot;ldaps://specific-server.ipa.dev.kanidm.com&quot;
# Path to the IPA CA certificate in PEM format.
ipa_ca = &quot;/path/to/kanidm-ipa-ca.pem&quot;
# The DN of an account with content sync rights. By default cn=Directory Manager has
# this access.
ipa_sync_dn = &quot;cn=Directory Manager&quot;
ipa_sync_pw = &quot;pi9aix6balaqu8Maerah&quot;
# The basedn to examine.
ipa_sync_base_dn = &quot;dc=ipa,dc=dev,dc=kanidm,dc=com&quot;
# The sync tool can alter or exclude entries. These are mapped by their syncuuid
# (not their ipa-object-uuid). The syncuuid is derived from nsUniqueId in 389-ds.
# This is chosen oven DN because DN's can change with modrdn where nsUniqueId is
# immutable and requires an entry to be deleted and recreated.
[ac60034b-3498-11ed-a50d-919b4b1a5ec0]
# my-problematic-entry
exclude = true
</code></pre>
<p>This example is located in <a href="https://github.com/kanidm/kanidm/blob/master/examples/kanidm-ipa-sync">examples/kanidm-ipa-sync</a>.</p>
<p>In addition to this, you must make some configuration changes to FreeIPA to enable synchronisation.</p>
<p>You must modify the retro changelog plugin to include the full scope of the database suffix.</p>
<pre><code>dn: cn=Retro Changelog Plugin,cn=plugins,cn=config
changetype: modify
add: nsslapd-include-suffix
nsslapd-include-suffix: dc=ipa,dc=dev,dc=kanidm,dc=com
</code></pre>
<p>You must then restart your FreeIPA server.</p>
<h2 id="running-the-sync-tool-manually"><a class="header" href="#running-the-sync-tool-manually">Running the Sync Tool Manually</a></h2>
<p>You can perform a dry run with the sync tool manually to check your configurations are
correct.</p>
<pre><code>kanidm-ipa-sync [-c /path/to/kanidm/config] -i /path/to/kanidm-ipa-sync -n
kanidm-ipa-sync -i /etc/kanidm/ipa-sync -n
</code></pre>
<h2 id="running-the-sync-tool-automatically"><a class="header" href="#running-the-sync-tool-automatically">Running the Sync Tool Automatically</a></h2>
<p>The sync tool can be run on a schedule if you configure the <code>schedule</code> parameter, and provide
the option &quot;--schedule&quot; on the cli</p>
<pre><code>kanidm-ipa-sync [-c /path/to/kanidm/config] -i /path/to/kanidm-ipa-sync --schedule
</code></pre>
<h2 id="monitoring-the-sync-tool"><a class="header" href="#monitoring-the-sync-tool">Monitoring the Sync Tool</a></h2>
<p>When running in schedule mode, you may wish to monitor the sync tool for failures. Since failures
block the sync process, this is important to ensuring a smooth and reliable synchronisation process.</p>
<p>You can configure a status listener that can be monitored via tcp with the parameter <code>status_bind</code>.</p>
<p>An example of monitoring this with netcat is:</p>
<pre><code># status_bind = &quot;[::1]:12345&quot;
# nc ::1 12345
Ok
</code></pre>
<p>It's important to note no details are revealed via the status socket, and is purely for Ok or Err status
of the last sync.</p>
