* Your virtual host configuration contains per-URL ``skip`` or ``unprotect`` access rule
In this situation, you have to update your LUA configuration file like ``/etc/nginx/nginx-lua-headers.conf``. See also `issue 2434 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2434>`__.
* It is now possible to hide sessions identifier in Manager (parameter ``displaySessionId``). See also `issue 2350 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2350>`__.
* Second factor management by end user now requires safer conditions. See also `issue 2332 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2332>`__, `issue 2337 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2337>`__ and `issue 2338 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2338>`__.
- RHEL/CentOS SELinux users should install the new ``lemonldap-ng-selinux`` package to fix `an issue with the new default cache directory <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2401>`__
- In the Manager API, postLogoutRedirectUri is now `returned and consumed as an array <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2347>`__
- We fixed a bug that caused SAML sessions to be created and never deleted, you should check your session databases for sessions that have ``"_session_kind": "ISAML"`` but no ``_utime``. You can safely delete SAML sessions with no ``_utime`` during the upgrade.
Or, better yet, integrate the changes in ``2fregisters.tpl`` and ``skin.min.js`` into your custom theme to benefit from the `new 2F removal confirmation dialog <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2438>`__
A CSS change has been done in ``styles.css`` to avoid checkbox labels overflow. See `issue 2301 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2301>`__.
The ``form-check-input`` class is missing in ``register.tpl`` and ``notifinclude.tpl``. See `issue 2374 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2374>`__.
Password checker
^^^^^^^^^^^^^^^^
Input id values have been modified in ``mail.tpl`` to work with password checker. See `issue 2355 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2355>`__.
Tables caption
^^^^^^^^^^^^^^
Tables captions have been added in ``sessionArray.tpl``. See `issue 2356 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2356>`__.
Stay connected
^^^^^^^^^^^^^^
A small change is required in ``checklogins.tpl`` for `issue 2365 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2365>`__.
Other changes needed in ``2fchoice.tpl``, ``ext2check.tpl``, ``totp2fcheck.tpl``, ``u2fcheck.tpl`` and ``utotp2fcheck.tpl`` for `issue 2366 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2366>`__.
Mails
^^^^^
The HTML ``alt`` attribute has been added on ``img`` in all ``mail_*.tpl``. See `issue 2422 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2422>`__.
- SAML SOAP calls are now using ``text/xml`` instead of ``application/xml`` as the MIME Content Type, as required by `the SOAP standard <https://www.w3.org/TR/2000/NOTE-SOAP-20000508/#_Toc478383526>`__
LDAP server certificates were previously not verified by default when using secure transports (LDAPS or TLS), see `CVE-2020-16093 <https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2250>`__. Starting from this release, certificate validation is now enabled by default, including on existing installations.
If you have configured your CA certificates incorrectly, LemonLDAP::NG will now start complaining about invalid certificates. You may temporarily disable it again with the following command ::
/your/path/to/lemonldap-ng-cli set ldapVerify none
If you use LDAP as a configuration storage, and want to temporarily disable certificate validation, you must make the following addition to `/etc/lemonldap-ng/lemonldap-ng.ini` ::
If you use LDAP as a session backend, you are strongly encouraged to also upgrade corresponding ``Apache::Session`` modules (``Apache::Session::LDAP`` or ``Apache::Session::Browseable``). After this upgrade, if you want to temporarily disable certificate validation, you can add the following parameter to the list of Apache::Session module options:
Please note that it is HIGHLY recommended to set certificate validation to `require` when contacting LDAP servers over a secure transport to avoid man-in-the-middle attacks.
