Connect to Renater Federation

Presentation

Renater provides an SAML federation for higher education in France.

It is based on SAMLv2 but add some specific items like a WAYF service and a metadata bundle to list all SP and IDP from the federation.

Since LL::NG 2.0, you can register into Renater federation.

Register as Service Provider

LL::NG configuration

Configure LL::NG as SAML Service Provider with this documentation. You don't need to declare any IDP for the moment.

Configure SAML Discovery Protocol to redirect users on WAYF Service. The endpoint URL is https://discovery.renater.fr/renater/WAYF.

Metadata import

You now need to import IDP metadata in LL::NG configuration. Use the importMetadata script that should be installed in /usr/share/lemonldap-ng/bin. You need to select the correct metadata bundle proposed by Renater: https://services.renater.fr/federation/technique/metadata, for example:

/usr/share/lemonldap-ng/bin/importMetadata -m https://metadata.federation.renater.fr/renater/main/main-idps-renater-metadata.xml -r -i "idp-renater" -s "sp-renater"
You need to add this in cron to refresh metadata into LL::NG configuration.

If you need too customize some settings of the script, copy it and edit configuration:

cp /usr/share/lemonldap-ng/bin/importMetadata /usr/share/lemonldap-ng/bin/importMetadataCustom
vi /usr/share/lemonldap-ng/bin/importMetadataCustom

Set attributes (use the SAML Name, not FriendlyName) that are provided by IDPs, for example:

my $exportedAttributes = {
    'cn'                          => '0;urn:oid:2.5.4.3',
    'eduPersonPrincipalName'      => '1;urn:oid:1.3.6.1.4.1.5923.1.1.1.6',
    'givenName'                   => '0;urn:oid:2.5.4.42',
    'sn'                          => '0;urn:oid:2.5.4.4',
    'eduPersonAffiliation'        => '0;urn:oid:1.3.6.1.4.1.5923.1.1.1.1',
    'eduPersonPrimaryAffiliation' => '0;urn:oid:1.3.6.1.4.1.5923.1.1.1.5',
    'mail'                        => '0;urn:oid:0.9.2342.19200300.100.1.3',
    'supannListeRouge'            => '0;urn:oid:1.3.6.1.4.1.7135.1.2.1.1',
    'supannEtuCursusAnnee'        => '0;rn:oid:1.3.6.1.4.1.5923.1.1.1.10',
};

Adapt IDP options, for example:

my $idpOptions = {
    'samlIDPMetaDataOptionsAdaptSessionUtime'        => 0,
    'samlIDPMetaDataOptionsAllowLoginFromIDP'        => 0,
    'samlIDPMetaDataOptionsAllowProxiedAuthn'        => 0,
    'samlIDPMetaDataOptionsCheckAudience'            => 1,
    'samlIDPMetaDataOptionsCheckSLOMessageSignature' => 1,
    'samlIDPMetaDataOptionsCheckSSOMessageSignature' => 1,
    'samlIDPMetaDataOptionsCheckTime'                => 1,
    'samlIDPMetaDataOptionsEncryptionMode'           => 'none',
    'samlIDPMetaDataOptionsForceAuthn'               => 0,
    'samlIDPMetaDataOptionsForceUTF8'                => 1,
    'samlIDPMetaDataOptionsIsPassive'                => 0,
    'samlIDPMetaDataOptionsNameIDFormat'             => 'transient',
    'samlIDPMetaDataOptionsRelayStateURL'            => 0,
    'samlIDPMetaDataOptionsSignSLOMessage'           => -1,
    'samlIDPMetaDataOptionsSignSSOMessage'           => -1,
    'samlIDPMetaDataOptionsStoreSAMLToken'           => 0,
    'samlIDPMetaDataOptionsUserAttribute' => 'urn:oid:1.3.6.1.4.1.5923.1.1.1.6',
};

Add your SP into the federation

Go to https://federation.renater.fr/registry and register your SP.

Be sure to check all attributes as mandatory to be able to get them in SAML assertions.

Register as Identity Provider

LL::NG configuration

Configure LL::NG as SAML Identity Provider with this documentation. You don't need to declare any SP for the moment.

Metadata import

You now need to import SP metadata in LL::NG configuration. Use the importMetadata script that should be installed in /usr/share/lemonldap-ng/bin. You need to select the correct metadata bundle proposed by Renater: https://services.renater.fr/federation/technique/metadata, for example:

/usr/share/lemonldap-ng/bin/importMetadata -m https://metadata.federation.renater.fr/renater/main/main-sps-renater-metadata.xml -r -i "idp-renater" -s "sp-renater"
You need to add this in cron to refresh metadata into LL::NG configuration.

If you need too customize some settings of the script, copy it and edit configuration:

cp /usr/share/lemonldap-ng/bin/importMetadata /usr/share/lemonldap-ng/bin/importMetadataCustom
vi /usr/share/lemonldap-ng/bin/importMetadataCustom

Adapt IDP options, for example:

my $spOptions = {
    'samlSPMetaDataOptionsCheckSLOMessageSignature'   => 1,
    'samlSPMetaDataOptionsCheckSSOMessageSignature'   => 1,
    'samlSPMetaDataOptionsEnableIDPInitiatedURL'      => 0,
    'samlSPMetaDataOptionsEncryptionMode'             => 'none',
    'samlSPMetaDataOptionsForceUTF8'                  => 1,
    'samlSPMetaDataOptionsNameIDFormat'               => '',
    'samlSPMetaDataOptionsNotOnOrAfterTimeout'        => 72000,
    'samlSPMetaDataOptionsOneTimeUse'                 => 0,
    'samlSPMetaDataOptionsSessionNotOnOrAfterTimeout' => 72000,
    'samlSPMetaDataOptionsSignSLOMessage'             => 1,
    'samlSPMetaDataOptionsSignSSOMessage'             => 1
};

Add your IDP into the federation

Go to https://federation.renater.fr/registry and register your IDP.
