I'm trying to configure Spring Security SAML 1.0.1 to reach a remote discovery service located at https://discovery.renater.fr/test. Instead, the IDP specified in property defaultIDP
of the "CachingMetadataManager" is reached.
In Spring Security SAML 1.0.1 documentation, we can read:
Remote discovery service
In order to enable external IDP discovery service, configure property
idpDiscoveryURL
in your local SP extended metadata to the external discovery URL. Make sure propertyidpDiscoveryEnabled
is set totrue
. The remote discovery service needs to support the Identity Provider Discovery Service Protocol and Profile.
Here is how I generate my SP Metadata :
<!-- Filter automatically generates default SP metadata -->
<b:bean id="metadataGeneratorFilter" class="org.springframework.security.saml.metadata.MetadataGeneratorFilter">
<b:constructor-arg>
<b:bean class="org.springframework.security.saml.metadata.MetadataGenerator">
<b:property name="includeDiscoveryExtension" value="true"/>
<b:property name="extendedMetadata">
<b:bean class="org.springframework.security.saml.metadata.ExtendedMetadata">
<b:property name="idpDiscoveryEnabled" value="true"/>
<b:property name="idpDiscoveryURL" value="https://discovery.renater.fr/test"/>
<b:property name="idpDiscoveryResponseURL" value="http://acem.u-bretagneloire.fr/ACEM/saml/login/alias/defaultAlias?disco=true"/>
</b:bean>
</b:property>
</b:bean>
</b:constructor-arg>
</b:bean>
As can be seen, I have set property includeDiscoveryExtension
to true
in bean MetadataGenerator
. I have also set properties idpDiscoveryEnabled
, idpDiscoveryURL
and idpDiscoveryResponseURL
in bean ExtendedMetadata
. But when I set the application's log-level to "TRACE", the idpDiscoveryURL
value is never displayed.
Question : what is missing in my configuration to reach the discovery URL?
