Do not forget to read the release notes of the version you are about to install for any specific instructions.

Upgrade from 2.0 to 2.1

SOAP deprecation

LLNG 2.1.x will be the last major version supporting SOAP services. Please start migration to REST services (available since 2.0.0).

Upgrade from 2.0.x to 2.0.y

Please apply general caution as you would with any software: have backups and a rollback plan ready!

Known issues

Upgrading from 2.0.0 or 2.0.1 to later versions

If you have installed LemonLDAP::NG from official RPMs, you may run into bug #1757 and lose your Apache configuration files while updating from LemonLDAP::NG 2.0.0 or 2.0.1 to later versions. Please backup your /etc/httpd/conf.d/z-lemonldap-ng-*.conf files before the update.

Known regressions in the latest released version

None

2.0.14

LemonLDAP::NG version is returned by the CheckState plugin

If you use the /checkstate URL to monitor LemonLDAP::NG, you may notice a slight change in the output format:

2.0.13 :

` {"result":1} `

2.0.14 :

` {"result":1,"version":"2.0.14"} `

Depending on your load balancer or monitoring configuration, this can cause false negatives.

This plugin is disabled by default, and you may use a shared secret to hide this information to regular users and bots, please check the Check state plugin documentation for more information.

Empty scopes now rejected in OAuth2.0 grants

Previously, it was possible to be granted an empty scope, or an automatic openid scope when doing OAuth2.0 Password Grant or Client Credentials Grant.

Starting with 2.0.14, empty scopes are no longer allowed (RFC 6749#section-3.3). You need to either add a scope parameter to your request, or define a default scope in your Relying Party’s Scope Rules.

Portal templates changes

If you defined the “Register page URL” or the password “Reset page URL” to an external application, you need to fix the standardform.tpl template by applying the following patch:

2.0.13

Portal templates changes

Some autocomplete attributes have been added to improve accessibility in the following files: checkdevops.tpl, checkuser.tpl, register.tpl, ext2fcheck.tpl, totp2fcheck.tpl, utotp2fcheck.tpl.

2.0.12

Security

  • CVE-2021-35473: Access token lifetime is not verified with OAuth2 Handler (see issue 2549)

  • CVE-2021-35472: Session cache corruption can lead to authorization bypass or spoofing (see issue 2539)

  • 2FA bypass with sfOnlyUpgrade and totp2fDisplayExistingSecret (see issue 2543)

  • Incorrect regexp construction in isTrustedUrl lets attacker steal session on CDA application (see issue 2535)

  • XSS on register form (see issue 2495)

  • Wildcard in virtualhost allows being redirected to untrusted domains (see issue 2477)

Portal templates changes

Email templates

If you customized the HTML email templates, you must update them to use HTML::Template variables (this was changed to fix XSS injections).

In the following files: mail_2fcode.tpl mail_certificateReset.tpl mail_footer.tpl mail_password.tpl mail_register_done.tpl mail_certificateConfirm.tpl mail_confirm.tpl mail_header.tpl mail_register_confirm.tpl

Replace the following variables:

Old syntax

New syntax

$code

<TMPL_VAR NAME="code" ESCAPE=HTML>

$url

<TMPL_VAR NAME="url" ESCAPE=HTML>

$login

<TMPL_VAR NAME="login" ESCAPE=HTML>

$password

<TMPL_VAR NAME="password" ESCAPE=HTML>

$firstname

<TMPL_VAR NAME="firstname" ESCAPE=HTML>

$lastname

<TMPL_VAR NAME="lastname" ESCAPE=HTML>

Replace all other variables such as $cn by <TMPL_VAR NAME="session_cn" ESCAPE=HTML>.

Login form

To benefit from the new feature allowing to show password on login form, adapt standardform.tpl (see changes)

To disable password store in browser when changing password (this was already possible for login form), adapt password.tpl (see changes)

To fix placeholder display in password field when password store is disabled in browser, adapt password.tpl (see changes)

TOTP

See also Simplification of TOTP options below.

FindUser, CheckDevOps templates

Some changes have been made to include new plugins (FindUser and CheckDevOps), you need to report them only if you have a custom theme and you want to use these plugins

Client Credential sessions missing expiration time

If you started using Client Credential grants in 2.0.11, you may have encountered issue 2481.

Because of this bug, the created sessions may never be purged by the purgeCentralCache script.

In order to detect these sessions, you can run the following command:

lemonldap-ng-sessions  search --where _session_kind=SSO --select _session_id --select _utime | \
jq -r  '. | map(select(._utime == null)) | map(._session_id) | join ("\n")'

This will output a list of SSO sessions with no expiration time.

Review them manually using

lemonldap-ng-sessions get <session_id>

You can then remove them with

lemonldap-ng-sessions delete <session_id> <session_id> <etc.>

Brute-force protection plugin may cause duplicate persistent sessions

Because of bug #2482 , some users may notice that the persistent session database is filling with duplicate sessions. Some examples include:

  • An uppercase version of the regular persistent session (dwho vs DWHO)

  • An unqualified version (dwho vs dwho@idp.com)

This bug was fixed in 2.0.12, but administrators are advised to clean up their persistent session database to remove any duplicate persistent sessions remaining after the upgrade.

OpenID Connect check session iframe

The OIDC check session iframe is not working, it has been removed from OIDC configuration metadata. It should not impact any installation as this feature was already broken.

Simplification of TOTP options

The following options have been removed from TOTP configuration:

  • Display existing secret (totp2fDisplayExistingSecret)

  • Change existing secret (totp2fUserCanChangeKey)

As a consequence, users who are not using the default bootstrap skin may need to ajust their totp2fregister.tpl template:

  • Move #divToHide from the .col-md-6 div to the .card div

  • Change:

    <pre id="serialized"></pre>

  • to:

    <br/><tt id="secret"></tt>

  • Remove the #changekey button

2.0.11

Portal templates changes

If you created your own skin and modified some template files, you may need to update them. No change is required if you are using the default bootstrap theme.

A new plugin has been introduced, in beta version: FindUser. It requires a modification of login.tpl to include finduser.tpl.

2.0.10

Security

A vulnerability affecting LemonLDAP::NG installations has been found out when ALL following criteria apply:

  • Your handler server uses Nginx

  • 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.

Other minor security fixes:

  • It is now possible to hide sessions identifier in Manager (parameter displaySessionId). See also issue 2350.

  • Second factor management by end user now requires safer conditions. See also issue 2332, issue 2337 and issue 2338.

Main changes

  • New dependency: IO::Socket::Timeout

  • TOTP check tolerates forward AND backward clock drift (totp2fRange)

  • Avoid assignment in expressions option is disabled by default

  • RHEL/CentOS SELinux users should install the new lemonldap-ng-selinux package to fix an issue with the new default cache directory

  • If you use Mattermost Team Edition with OpenID Connect, you need to set the id claim type to Integer

  • BruteForceProtection plugin now prevents authentication on backend if an account is locked

  • In the Manager API, postLogoutRedirectUri is now returned and consumed as an array

  • 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.

Portal templates changes

If you created your own skin and modified some template files, you may need to update them, see below if they have been modified.

No change is required if you are using the default bootstrap theme.

2FA manager

In 2fregisters.tpl you need to add the remove2f class to the button that triggers second factor removal:

- <span device='<TMPL_VAR NAME="type">' epoch='<TMPL_VAR NAME="epoch">' class="btn btn-danger" role="button">
+ <span device='<TMPL_VAR NAME="type">' epoch='<TMPL_VAR NAME="epoch">' class="btn btn-danger remove2f" role="button">

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

Checkboxes

A CSS change has been done in styles.css to avoid checkbox labels overflow. See issue 2301.

The form-check-input class is missing in register.tpl and notifinclude.tpl. See issue 2374.

Password checker

Input id values have been modified in mail.tpl to work with password checker. See issue 2355.

Tables caption

Tables captions have been added in sessionArray.tpl. See issue 2356.

Stay connected

A small change is required in checklogins.tpl for issue 2365.

Other changes needed in 2fchoice.tpl, ext2check.tpl, totp2fcheck.tpl, u2fcheck.tpl and utotp2fcheck.tpl for issue 2366.

Mails

The HTML alt attribute has been added on img in all mail_*.tpl. See issue 2422.

2.0.9

  • Bad default value to display OIDC Consents tab has been fixed. The default value is now: $_oidcConsents && $_oidcConsents =~ /\w+/

  • Some user log messages have been modified, check logs documentation (see also #2244)

  • SAML SOAP calls are now using text/xml instead of application/xml as the MIME Content Type, as required by the SOAP standard

  • Incremental lock times values can now be set in BruteForceProtection plugin through Manager. It MUST be a list of comma separated values. Default values are 5, 15, 60, 300, 600

  • This version is not compatible with Mattermost Team Edition

Change in default cache directory

The default config/session cache directory has been moved from /tmp to /var/cache/lemonldap-ng in order to avoid issues with cache purges when using Systemd. This change is only applied to new installations. If your installation is experiencing cache purge issues, you need to manually change your existing localSessionStorageOptions/cache_root parameter from /tmp to /var/cache/lemonldap-ng. Be sure to create this directory on your file system before modifying your configuration.

If you are using SELinux, you also need to run the following commands

semanage fcontext --add -t httpd_cache_t -f a '/var/cache/lemonldap-ng(/.*)?'
restorecon -R /var/cache/lemonldap-ng/

Required changes in NGINX handler rules (CVE-2020-24660)

We discovered a vulnerability that affects LemonLDAP::NG installations when ALL of the following criteria apply:

  • You are using the LemonLDAP::NG Handler to protect applications

  • Your handler server uses Nginx

  • Your virtual host configuration contains per-URL access rules based on regular expressions in addition to the built-in default access rule.

Note

You are safe from this vulnerability if your virtualhost only uses a regexp-based rule to trigger logout

If you are in this situation, you need to modify all your handler-protected virtualhosts by making the following change:

  • Replace fastcgi_param X_ORIGINAL_URI $request_uri by fastcgi_param X_ORIGINAL_URI $original_uri if you are using FastCGI

  • Replace uwsgi_param X_ORIGINAL_URI $request_uri by uwsgi_param X_ORIGINAL_URI $original_uri if you are using uWSGI

  • Right after auth_request /lmauth;, add the following line

    set $original_uri $uri$is_args$args;

You can check the Manage virtual hosts page for more information

LDAP certificate validation (CVE-2020-16093)

LDAP server certificates were previously not verified by default when using secure transports (LDAPS or TLS), see CVE-2020-16093. 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

[configuration]
...
ldapVerify = none

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:

  • key: ldapVerify

  • value: none

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.

2.0.8

  • New dependency: Perl module Time::Fake is now required to run unit test and build packages, but should not be mandatory to run the software.

  • Nginx configuration: some changes are required to allow IPv6, see #2152

  • Option singleSessionUserByIP was removed, see #2159

  • A memory leak was found in perl-fcgi with Perl < 5.18, a workaround is possible with Apache and llng-fastcgi-server, see #1314

    • With Apache: set FcgidMaxRequestsPerProcess 500 in portal virtual host

    • With llng-fastcgi-server: set PM_MAX_REQUESTS=500 in llng-fastcgi-server service configuration

  • Cookie SameSite value: to avoid problems with recent browsers, SAML POST binding, LLNG cookies are now tagged as “SameSite=None”. You can change this value using manager, “SameSite=Lax” is best for installations without federations. Important note: if you’re using an unsecured connection (http:// instead of https://), “SameSite=None” will be ignored by browsers and users that already have a valid session might be prompted to login again.

  • OAuth2.0 Handler: a VHost protected by the OAuth2.0 handler will now return a 401 when called without an Access Token, instead of redirecting to the portal, as specified by RFC 6750#section-3.

  • If you encounter the following issue:

AH01630: client denied by server configuration: /usr/share/lemonldap-ng/manager/api/api.fcgi

when trying to access the portal. It probably comes from incorrect Apache configuration. Remove the (optional and disabled by default) manager API config:

rm /etc/httpd/conf.d/z-lemonldap-ng-api.conf && systemctl reload httpd

2.0.7

  • Security:

    • #2040: Configuration of a redirection URI for an OpenID Connect Relying Party is now mandatory, as defined in the specifications. If you save your configuration, you will have an error if some of your RP don’t have a redirect URI configured.

    • #1943 / CVE-2019-19791: along with the patch provided in 2.0.7 in Lemonldap/NG/Common/PSGI/Request.pm, Apache rewrite rule must be updated to avoid an unprotected access to REST services:

portal-apache2.conf

RewriteCond "%{REQUEST_URI}" "!^/(?:(?:static|javascript|favicon).*|.*\.fcgi(?:/.*)?)$"
RewriteRule "^/(.+)$" "/index.fcgi/$1" [PT]

manager-apache2.conf

RewriteCond "%{REQUEST_URI}" "!^/(?:static|doc|lib|javascript|favicon).*"
RewriteRule "^/(.+)$" "/manager.fcgi/$1" [PT]

  • Other:

    • Option checkTime was enabled by default in lemonldap-ng.ini, this let the portal check the configuration immediately instead of waiting for configuration cache expiration. You can keep this option enabled unless you need strong performances.

  • Removed parameters:

    • samlIdPResolveCookie

2.0.6

  • Option was added to display generate password box in password reset by mail plugin. If you use this feature, you must enable this option, which is disabled by default.

  • If you use the default _whatToTrace macro and a case insensitive authentication backend, then a user can generate several persistent sessions for the same login (see issue 1869). This can lead to a security bug if you enabled 2FA, which rely on data stored in the persistent session. To fix this, either choose a unique attribute for _whatToTrace, either force lower case in your macro:

$_auth eq 'SAML' ? lc($_user.'@'.$_idpConfKey) : $_auth eq 'OpenIDConnect' ? lc($_user.'@'.$_oidc_OP) : lc($_user)

  • On CentOS 7 / RHEL 7, a system upgrade breaks ImageMagick, which is used to display captchas (see #1951). To fix this, you can run the following commands:

yum install -y urw-base35-fonts-legacy
sed 's,/usr/share/fonts/default/Type1/,/usr/share/X11/fonts/urw-fonts/,g' -i /etc/ImageMagick/type-ghostscript.xml

2.0.5

  • The Text::Unidecode perl module becomes a requirement (it will be automatically installed if you upgrade from from the deb or RPM repositories)

  • CAS logout starts validating the service= parameter, but only if you use the CAS Access control policy. The URL sent in the service= parameter will be checked against known CAS applications, Virtual Hosts, and trusted domains. Add your target domain to trusted domains if you suddenly start having “Invalid URL” messages on logout

  • Improvements in cryptographic functions: to take advantage of them, you must change the encryption key of LemonLDAP::NG (see CLI example).

  • Debian packaging: FastCGI / uWsgi servers require llng-lmlog.conf and llng-lua-headers.conf. Those configuration files are now provided by lemonldap-ng-handler package and installed in /etc/nginx/snippets directory.

Upgrade from 1.9 to 2.0

Attention

2.0 is a major release, lot of things have been changed. You must read this document before upgrade.

Upgrade order from 1.9.*

As usual, if you use more than 1 server and don’t want to stop SSO service AND IF YOU HAVE NO INCOMPATIBILITY MENTIONED IN THIS DOCUMENT, upgrade must be done in the following order:

  1. servers with handlers only;

  2. portal servers (all together if your load balancer is stateless (user or client IP) and if users use the menu);

  3. manager server

Attention

You must revalidate your configuration using the manager.

Installation

Attention

French documentation is no more available. Only English version of this documentation is maintained now.

This release of LL::NG requires these minimal versions of GNU/Linux distributions:

  • Debian 9 (stretch)

  • Ubuntu 16.04 LTS

  • CentOS 7

  • RHEL 7

For SAML features, we require at least Lasso 2.5 and we recommend Lasso 2.6.

Configuration

  • lemonldap-ng.ini requires some new fields in portal section. Update yours using the one given installed by default. New requires fields are:

    • staticPrefix (manager and portal): the path to static content

    • templateDir (manager and portal): the path to templates directory

    • languages (manager and portal): accepted languages

  • Portal skins are now in /usr/share/lemonldap-ng/portal/templates. See skin customization to adapt your templates.

  • User module in authentication parameters now provides a “Same as authentication” value. You must revalidate it in the manager since all special values must be replaced by this (Multi, Choice, Proxy, Slave, SAML, OpenID,…)*

  • “Multi” doesn’t exist anymore: it is replaced by Combination, a more powerful module.

  • Apache and Nginx configurations must be updated to use FastCGI portal

  • URLs for mail reset and register pages have changed, you must update configuration parameters. For example:

mailUrl => 'http://auth.example.com/resetpwd',
registerUrl => 'http://auth.example.com/register',

Attention

Apache mod_perl has got lot of troubleshooting problems since 2.4 version (many segfaults,…), especially when using MPM worker or MPM event. That’s why LL::NG doesn’t use anymore ModPerl::Registry: all is now handled by FastCGI (portal and manager), except for Apache2 Handler.

For Handlers, it is now recommended to migrate to Nginx, but Apache 2.4 is still supported with MPM prefork.

Configuration refresh

Now portal has the same behavior than handlers: it looks to configuration stored in local cache every 10 minutes. So it has to be reload like every handler.

Attention

If you want to use reload mechanism on a portal only host, you must install a handler in Portal host to be able to refresh local cache. Include handler-nginx.conf or handler-apache2.conf for example

LDAP connection

Now LDAP connections are kept open to improve performances. To allow that, LL::NG requires an anonymous access to LDAP RootDSE entry to check connection.

Kerberos or SSL usage

  • A new Kerberos authentication backend has been added since 2.0. This module solves many Kerberos integration problems (usage in conjunction with other backends, better error display,…). However, you can retain the old integration manner (using Apache authentication module).

  • For SSL, a new Ajax option can be used in the same idea: so SSL can be used in conjunction with other backends.

Logs

  • Syslog: logs are now configured in lemonldap-ng.ini file only. If you use Syslog, you must reconfigure it. See logs for more.

  • Apache2: Portal doesn’t use anymore Apache2 logger. Logs are always written to Apache error.log but Apache “LogLevel” parameter has no more effect on it. Portal is now a FastCGI application and doesn’t use anymore ModPerl. See logs for more.

  • If you are running behind a proxy, make sure LemonLDAP::NG can see the original IP address of incoming HTTP connections

Security

LLNG portal now embeds the following features:

  • CSRF protection (Cross-Site Request Forgery): a token is build for each form. To disable it, set requireToken to 0 (portal security parameters in the manager)

  • Content-Security-Policy header: portal build dynamically this header. You can modify default values in the manager (Général parameters » Advanced parameters » Security » Content-Security-Policy)

Handlers

  • Apache only:

    • Apache handler is now Lemonldap::NG::Handler::ApacheMP2 and Menu is now Lemonldap::NG::Handler::ApacheMP2::Menu

    • because of an Apache behaviour change, PerlHeaderParserHandler must no more be used with “reload” URLs (replaced by PerlResponseHandler). Any “reload url” that are inside a protected vhost must be unprotected in vhost rules (protection has to be done by web server configuration).

  • CDA, ZimbraPreAuth, SecureToken and AuthBasic are now Handler Types. So there is no more special file to load: you just have to choose “VirtualHost type” in the manager/VirtualHosts.

  • SSOCookie: Since Firefox 60 and Chrome 68, “+2d, +5M, 12h and so on…” cookie expiration time notation is no more supported. CookieExpiration value is a number of seconds until the cookie expires. A zero or negative number will expire the cookie immediately.

Rules and headers

  • hostname() and remote_ip() are no more provided to avoid some name conflicts replaced by `$ENV{}`)

  • $ENV{<cgi_variable>} is now available everywhere: see Writing rules and headers

  • some variable names have changed. See Variables document

Opening conditions

  • Rule and message fields have been swaped. You have to modifiy and validate again your access rules.

Supported servers

  • Apache-1.3 files are not provided now. You can build them yourself by looking at Apache-2 configuration files

Ajax requests

Before 2.0, an Ajax query launched after session timeout received a 302 code. Now a 401 HTTP code is returned. WWW-Authenticate header contains: SSO <portal-URL>

SOAP/REST services

  • SOAP server activation is now split in 2 parameters (configuration/sessions). You must set them else SOAP service will be disabled

  • Notifications are now REST/JSON by default. You can force old format in the manager. Note that SOAP proxy has changed: http://portal/notifications now.

  • If you use “adminSessions” endpoint with “singleSession*” features, you must upgrade all portals simultaneously

  • SOAP services can be replaced by new REST services

Attention

AuthBasic Handler uses now REST services instead of SOAP.

CAS

CAS authentication module no more use perl CAS client, but our own code. You can now define several CAS servers in a specific branch in Manager, like you can define several SAML or OpenID Connect providers.

CAS issuer module has also been improved, you must modify the configuration of CAS clients to move them from virtual host branch to CAS client branch.

Developer corner

APIs

Portal has now many REST features and includes an API plugin. See Portal manpages to learn how to write auth modules, issuers or other features.

Portal overview

Portal is no more a single CGI object. Since 2.0, It is based on Plack/PSGI and Mouse modules. Little resume

Portal object
  |
  +-> auth module
  |
  +-> userDB module
  |
  +-> issuer modules
  |
  +-> other plugins (notification,...)

Requests are independent objects based on Lemonldap::NG::Portal::Main::Request which inherits from Lemonldap::NG::Common::PSGI::Request which inherits from Plack::Request. See manpages for more.

Handler

Handler libraries have been totally rewritten. If you’ve made custom handlers, they must be rewritten, see customhandlers.

If you used self protected CGI, you also need to rewrite them, see documentation.
