Connect to Renater Federation
=============================
|image0|
Presentation
------------
`Renater <https://www.renater.fr/>`__ 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
:doc:`documentation<authsaml>`. You don't need to declare any IDP for
the moment.
Configure :ref:`SAML Discovery Protocol<samlservice-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 Renater, you need to customize some settings of the script, copy it
and edit configuration:
::
cp /usr/share/lemonldap-ng/bin/importMetadata /usr/share/lemonldap-ng/bin/importMetadataRenater
vi /usr/share/lemonldap-ng/bin/importMetadataRenater
.. versionchanged:: 2.0.15
Since version 2.0.15 it is no longer necessary to copy the script, you can
use the ``--configfile`` option to handle most customization use cases. See
:ref:`importmetadataconfig` below for details.
Set attributes (use the SAML Name, not FriendlyName) that are provided
by IDPs, for example:
.. code-block:: perl
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:
.. code-block:: perl
my $idpOptions = {
'samlIDPMetaDataOptionsAdaptSessionUtime' => 0,
'samlIDPMetaDataOptionsAllowLoginFromIDP' => 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',
};
Then run the script:
::
/usr/share/lemonldap-ng/bin/importMetadataRenater -m https://metadata.federation.renater.fr/renater/main/main-idps-renater-metadata.xml -r -i "idp-renater-" -s "sp-renater-"
The script provide the following options
* -i (--idpconfprefix): Prefix used to set IDP configuration key
* -h (--help): print this message
* -m (--metadata): URL of metadata document
* -s (--spconfprefix): Prefix used to set SP configuration key
* --ignore-sp: ignore SP matching this entityID (can be specified multiple times)
* --ignore-idp: ignore IdP matching this entityID (can be specified multiple times)
* -a (--nagios): output statistics in Nagios format
* -n (--dry-run): print statistics but do not apply changes
* -c (--configfile): use a configuration file
* -v (--verbose): increase verbosity of output
* -r (--remove): remove provider from LemonLDAP::NG if it does not appear in metadata
Example :
::
/usr/libexec/lemonldap-ng/bin/importMetadata -m https://pub.federation.renater.fr/metadata/renater/main/main-sps-renater-metadata.xml -s "sp-fed-prd" -c https://pub.federation.renater.fr/metadata/certs/renater-metadata-signing-cert-2016.pem -bs https://test-sp.federation.renater.fr -r -v -d
This command will
* fetch all SPs metadata from renater
* set a prefix to entity stored inside LemonLdap::NG
* disable local modification of SP https://test-sp.federation.renater.fr
* remove local SPs wich didn't exist anymore in Federation metadata
* show only all modifications to apply
The output is the following :
::
...
Update SP https://www-iuem.univ-brest.fr/sp in configuration
Attribute mail (urn:oid:0.9.2342.19200300.100.1.3) requested by SP https://gesper.ad.bnu.fr/shibboleth
Attribute eduPersonPrimaryAffiliation (urn:oid:1.3.6.1.4.1.5923.1.1.1.5) requested by SP https://gesper.ad.bnu.fr/shibboleth
Attribute eduPersonPrincipalName (urn:oid:1.3.6.1.4.1.5923.1.1.1.6) requested by SP https://gesper.ad.bnu.fr/shibboleth
Attribute displayName (urn:oid:2.16.840.1.113730.3.1.241) requested by SP https://gesper.ad.bnu.fr/shibboleth
Update SP https://gesper.ad.bnu.fr/shibboleth in configuration
[INFO] Dry-run mod no EntityID inserted

[SP] Found: 1248 Updated: 1240 Created: 0 Removed: 0 Rejected: 7 Ignored: 1
With "-n" options you could get a "nagios like" output with metrics :
::
/usr/libexec/lemonldap-ng/bin/importMetadataFedRenater -m https://pub.federation.renater.fr/metadata/renater/main/main-sps-renater-metadata.xml -s "sp-fed-prd" -c https://pub.federation.renater.fr/metadata/certs/renater-metadata-signing-cert-2016.pem -bs https://test-sp.federation.renater.fr -r -d -n
Metadata loaded inside Conf: [DRY-RUN]|idp_found=0, idp_updated=0, idp_created=0, idp_removed=0, idp_rejected=0, idp_ignored=0, sp_found=1248, sp_updated=1240, sp_created=0, sp_removed=0, sp_rejected=7, sp_ignored=1
.. attention::
You need to add this in cron to refresh metadata into
LL::NG configuration.
.. _importmetadataconfig:
Metadata import configuration file
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. versionadded:: 2.0.15
You can now use a configuration file for the script in order to handle most custom cases.
Here is an example of a INI-formatted configuration file::
# main script options, these will be overriden by the CLI options
[main]
dry-run=1
verbose=1
metadata=http://url/to/metadata.xml
; Multi-value options
ignore-idp=entity-id-to-ignore-1
ignore-idp=entity-id-to-ignore-2
# Default exported attributes for IDPs
[exportedAttributes]
cn=0;cn
eduPersonPrincipalName=0;eduPersonPrincipalName
...
# options that apply to all providers
[ALL]
; Disable signature requirement on requests
samlSPMetaDataOptionsCheckSSOMessageSignature=0
samlSPMetaDataOptionsCheckSLOMessageSignature=0
; Store SAML assertions in session
samlIDPMetaDataOptionsStoreSAMLToken=1
; Mark ePPN as always required
attribute_required_eduPersonPrincipalName=1
...
# Specific provider configurations
[https://test-sp.federation.renater.fr]
; All attributes are optional for this provider
attribute_required=0
; Override some options
samlSPMetaDataOptionsNameIDFormat=persistent
[https://idp.renater.fr/idp/shibboleth]
; declare an extra attribute from this provider
exported_attribute_eduPersonAffiliation=1;uid
Add your SP into the federation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Go to https://federation.renater.fr/registry and register your SP.
.. attention::
Be sure to check all attributes as mandatory to be able
to get them in SAML assertions.
Register as Identity Provider
-----------------------------
.. _llng-configuration-renater-1:
LL::NG configuration
~~~~~~~~~~~~~~~~~~~~
Configure LL::NG as SAML Identity Provider with this
:doc:`documentation<idpsaml>`. You don't need to declare any SP for the
moment.
.. attention::
If your LL::NG server will act as SP and IDP inside
Renater federation, you need to set the advanced parameter "Override
Entity ID for IDP". Indeed, Renater do not allow to register a SP and an
IDP with the same entityID.
.. _metadata-import-1:
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 Renater, you may need to customize some settings of the script, copy
it and edit configuration:
::
cp /usr/share/lemonldap-ng/bin/importMetadata /usr/share/lemonldap-ng/bin/importMetadataRenater
vi /usr/share/lemonldap-ng/bin/importMetadataRenater
Adapt IDP options, for example:
.. code-block:: perl
my $spOptions = {
'samlSPMetaDataOptionsCheckSLOMessageSignature' => 1,
'samlSPMetaDataOptionsCheckSSOMessageSignature' => 1,
'samlSPMetaDataOptionsEnableIDPInitiatedURL' => 0,
'samlSPMetaDataOptionsEncryptionMode' => 'none',
'samlSPMetaDataOptionsForceUTF8' => 1,
'samlSPMetaDataOptionsNameIDFormat' => '',
'samlSPMetaDataOptionsNotOnOrAfterTimeout' => 72000,
'samlSPMetaDataOptionsOneTimeUse' => 0,
'samlSPMetaDataOptionsSessionNotOnOrAfterTimeout' => 72000,
'samlSPMetaDataOptionsSignSLOMessage' => 1,
'samlSPMetaDataOptionsSignSSOMessage' => 1
};
Then run the script:
::
/usr/share/lemonldap-ng/bin/importMetadataRenater -m https://metadata.federation.renater.fr/renater/main/main-sps-renater-metadata.xml -r -i "idp-renater" -s "sp-renater"
.. attention::
You need to add this in cron to refresh metadata into
LL::NG configuration.
Add your IDP into the federation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
