Handlers

Handlers are software control agents to be installed on your web servers (Nginx, Apache, PSGI like Plack based servers or Node.js).

Handler type Apache Nginx Plack* servers Node.js Comment
Main (default handler) Partial (*)
AuthBasic Designed for some server-to-server applications
CDA For Cross Domain Authentication
DevOps (SSOaaS) Allows application developers to define their own rules and headers inside their applications
DevOpsST (SSOaaS) Enables both DevOps and Service Token
Secure Token Designed to secure exchanges between a LLNG reverse-proxy and a remote app
Service Token (Server-to-Server) Designed to permit underlying requests (API-Based Infrastructure)
Zimbra PreAuth

(*): Node.js handler has not yet reached the same level of functionalities.

LLNG databases

Configuration database

LL::NG needs a storage system to store its own configuration (managed by the manager). Choose one in the following list:

Backend Shareable Comment
File (JSON) Not shareable between servers except if used in conjunction with REST or with a shared file system (NFS,…). Selected by default during installation.
YAML Same as File but in YAML format instead of JSON
SQL (RDBI/CDBI) Recommended for large-scale systems. Prefer CDBI.
LDAP
MongoDB
SOAP (deprecated) Proxy backend to be used in conjunction with another configuration backend.
Can be used to secure another backend for remote servers.
REST Proxy backend to be used in conjunction with another configuration backend.
Can be used to secure another backend for remote servers.
Local Use only lemonldap-ng.ini parameters.
You can not start with an empty configuration, so read how to change configuration backend to convert your existing configuration into another one.

Sessions database

Sessions are stored using Apache::Session modules family. All Apache::Session style modules are usable except for some features.

If you plan to use LLNG in a large-scale system, take a look at Performance Test to choose the right backend. A Browseable SQL backend is generally a good choice.
Backend Shareable Session explorer Session restrictions Session expiration Comment
File Not shareable between servers except if used in conjunction with REST session backend or with a shared file system (NFS,…). Selected by default during installation.
SQL Unoptimized for session explorer and single session features.
LDAP
Redis The fastest. Must be secured by network access control.
MongoDB Must be secured by network access control.
Browseable (SQL, Redis or LDAP) Optimized for session explorer and single session features.
REST Proxy backend to be used in conjunction with another session backend.
Can be used to secure another backend for remote servers.
SOAP (deprecated) Proxy backend to be used in conjunction with another session backend.
Can be used to secure another backend for remote servers.

Developer corner

To develop an handler, see:

To develop a portal plugin, see manpages:

  • Lemonldap::NG::Portal
  • Lemonldap::NG::Portal::Auth
  • Lemonldap::NG::Portal::UserDB
  • Lemonldap::NG::Portal::Main::SecondFactor
  • Lemonldap::NG::Portal::Main::Issuer
  • Lemonldap::NG::Portal::Main::Plugin
  • Lemonldap::NG::Portal::Main::Request (the request object)

To add a new language:

If you don't want to publish your translation (XX must be replaced by your language code):

  • Manager: translate lemonldap-ng-manager/site/htdocs/static/languages/en.json in lemonldap-ng-manager/site/htdocs/static/languages/XX.json and enable it in “lemonldap-ng.ini” file
  • Portal: translate lemonldap-ng-portal/site/htdocs/static/languages/en.json in lemonldap-ng-portal/site/htdocs/static/languages/XX.json and enable it in “lemonldap-ng.ini” file
  • Portal Mails: translate lemonldap-ng-portal/site/templates/common/mail/en.json in lemonldap-ng-portal/site/templates/common/mail/XX.json
