Lemonldap::NG::Portal::Main::Issuer - Base class for identity providers.


  package Lemonldap::NG::Portal::Issuer::My;
  use strict;
  use Mouse;
  extends 'Lemonldap::NG::Portal::Main::Issuer';
  use Lemonldap::NG::Portal::Main::Constants qw(PE_OK);
  # Required: URL root path
  use constant path => 'saml';
  # Optional initialization method
  sub init {
      my ($self) = @_;
      # Must return 1 (succeed) or 0 (failure)
  # Required methods are run() and logout(), they are launched only for
  # authenticated users
  # $req is a Lemonldap::NG::Portal::Main::Request object
  # They must return a Lemonldap::NG::Portal::Main::Constants constant
  sub run {
      my ( $self, $req ) = @_
      return PE_OK
  sub logout {
      my ( $self, $req ) = @_
      return PE_OK


Lemonldap::NG::Portal::Main::Issuer is a base class to write identity providers for Lemonldap::NG web-SSO system. It provide several methods to write easily an IdP and manage authentication if the identity request comes before authentication.


To write a classic identity provider, you just have to inherit this class and write run() and logout() methods. These methods must return a Lemonldap::NG::Portal::Main::Constants constant.

A classic identity provider needs a "issuerDB>XXX<Path" parameter in LLNG configuration to declare its base URI path (see Lemonldap::NG::Manager::Build). Example: /saml/. All requests that starts with /saml/ will call run() after authentication if needed, and no one else.

The logout() function is called when user asks for logout on this server. If you want to write an identity provider, you must implement a single logout system.

managing other URI path

Lemonldap::NG::Portal::Main::Issuer provides methods to bind a method to an URI path:

They must be called during initialization process (so you must write the optional init() sub).

Be careful with "add*authRoute()": you can't catch here your root path (= path declared in "$self->path") because it is caught by this module, but you can catch sub-routes (ie "/path/something").


  sub init {
      my ($self) = @_;
      $self->addUnauthRoute( saml => { soap => 'soapServer' }, [ 'POST' ] );
      return 1;
  sub soapServer {
      my ( $self, $req ) = @_;
      # You must return a valid PSGI response
      return [ 200, [ 'Content-Type' => 'application/xml' ], [] ];

avoid conflicts in path

If you share base URI path with another plugin (a "Auth::*" module for example), it is recommended to write a "ssoMatch" function that returns true if "$req->uri" has to be handled by Issuer module. See "Issuer::SAML" or "Issuer::OpenIDConnect" to have some examples.
