  sub validateAudience {
    my ( $self, $req, $rp, $target, $requestedTokenType ) = @_;
    #
    # verify and update if needed:
    # * $target->{audience}
    # * $target->{rp}
    #
    return 1;
  }
  
  sub getUid {
    my ( $self, $req, $rp, $subjectToken, $subjectTokenType ) = @_;
    #

Overview

When Lemonldap::NG <https://lemonldap-ng.org> detects a Oauth2 token exchange <https://datatracker.ietf.org/doc/html/rfc8693> request, it searches for a plugin able to respond. If no one returns a valid response, it rejects the requests.

Lemonldap::NG::Portal::Lib::OIDCTokenExchange permits one to build such plugin by just writing two methods. Of course you need then to load the module for example using Enabling custom plugin <https://lemonldap-ng.org/documentation/latest/plugincustom.html#enabling-your-plugin>.

Methods to write

validateAudience

The goal of validateAudience() is to validate the requested audience.

If a non-null value is returned, then the request is accepted and Lemonldap::NG will build new "access_token", "id_token" and "refresh_token" using the values included into $target hash.

If a null value is returned, Lemonldap::NG will try the next plugin.

Parameters:

•: $req, the Lemonldap::NG::Portal::Main::Request object

•: $rp, the internal LLNG name of the Relying Party which pushed the request

•

$target, a hash value with 2 keys:

•: audience, the requested audience

•: rp: if Lemonldap::NG found a known Relying Party which Client-ID matches with requested audience, its name is put here, else this value is undefined.

This value can be modified inside "validateAudience" and will be used to generate the new "access_token".

•

$requestedTokenType, the type of the requested token. This value is always one of:

•: access_token

•: refresh_token

•: id_token

•: saml1

•: saml2

•: undef

getUid

getUid() is a boolean method to validate the token given in the request.

If a non-null value is returned, then the request is accepted. Else Lemonldap::NG will try the next plugin.

Parameters:

•: $req, the Lemonldap::NG::Portal::Main::Request object

•: $rp, the internal LLNG name of the Relying Party which pushed the request

•: $subjectToken, the token given in the request

•

$subjectTokenType, the type of the given token. This value is always one of:

•: access_token

•: refresh_token

•: id_token

•: saml1

•: saml2

•: undef
