An R&S IdP will carry either the incommon.org R&S tag or the refeds.org R&S tag but not both. An SP that depends on the R&S entity attribute in IdP metadata must take this fact into account. |
For example, a Shibboleth SP that restricts To configure an instance of Shibboleth SP 2.5 (and later) to restrict its discovery interface to R&S IdPs might configure the following <MetadataProvider>
, add the following DiscoveryFilter
to your MetadataProvider
:

<!-- The following MetadataProvider attempts to refresh the InCommon production metadata aggregate every hour. --> <MetadataProvider type="XML" url="http://md.incommon.org/InCommon/InCommon-metadata.xml" backingFilePath="InCommon-metadata.xml" maxRefreshDelay="3600" legacyOrgNames="true"> <!-- Verify the signature on the metadata file --> <MetadataFilter type="Signature" certificate="inc-md-cert.pem"/> <!-- Require a validUntil XML attribute on the EntitiesDescriptor element and make sure its value is no more than 14 days into the future --> <MetadataFilter type="RequireValidUntil" maxValidityInterval="1209600"/> <!-- As the refeds.org R&S tag becomes more prevalent, the order of the attributes should be reversed for efficiency. --> <DiscoveryFilter type="Whitelist" matcher="EntityAttributes"> <saml:Attribute Name="http://macedir.org/entity-category-support" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri"> <saml:AttributeValue>http://id.incommon.org/category/research-and-scholarship</saml:AttributeValue> </saml:Attribute> <saml:Attribute Name="http://macedir.org/entity-category-support" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri"> <saml:AttributeValue>http://refeds.org/category/research-and-scholarship</saml:AttributeValue> </saml:Attribute> </DiscoveryFilter> </MetadataProvider> |
The above configuration requires Shibboleth SP v2.5 (or later). Be aware that filtering entity metadata from the discovery interface is not the same as filtering the metadata in the first place. If the latter is really what you want to do, replace the <DiscoveryFilter>
with an identical <MetadataFilter>
as in the previous example.
See the Shibboleth Metadata Config topic for a complete example of a MetadataProvider
. The above DiscoveryFilter
element may be added to that MetadataProvider
.
