What Kostas said! Perhaps what is needed is a feature to generate service definitions (in memory) for each [SP] entry in federated metadata (during parsing of metadata). With filters, allow and deny lists could be created, attributes to release set, and other conditions (like MFA) could be added to the service definition.
This would be a good 4th year project. Ray On Tue, 2024-02-20 at 22:28 -0800, Kostas Kalevras wrote: Notice: This message was sent from outside the University of Victoria email system. Please be cautious with links and sensitive information. That is actually negating the whole point. The point is that the federated services registrar is the one maintaining the services metadata. The IdP on the other hand does not have to worry about individual services but only has to setup agroup service definition with a URL metadata endpoint which is regularly updated automatically. In the shibboleth case, when setting up an <AttributeFilterPolicy> in attribute-filter.xml, one can use theInEntityGroup<https://shibboleth.atlassian.net/wiki/spaces/IDP30/pages/2496987441/InEntityGroupConfiguration> policy rule to match the names of any of the <EntitiesDescriptor> in the relevant metadata and make the rule apply toall of the SPs that are included in the metadata. As a result we can include something like the following: <AttributeFilterPolicy id="edugain"> <PolicyRequirementRule xsi:type="AND"> <Rule xsi:type="InEntityGroup" groupID="http://edugain.org/"; /> I am not aware of a corresponding functionality in Apereo CAS which has the result that we must maintain a Shibboleth installation only to handle Federated services.

We did find we could add multiple services with the same metadata (Like the almond and coco examples) and those are working fine. It may be that you need to define each service you want to work with.

We are using a MariaDB as our service definition data store. We are investigating the possibility of migrating federated SAML services to CAS as well. There are a lot of quite helpful references on the fawnoos blog site such asthis<https://fawnoos.com/2019/01/18/cas61-saml2-idp-incommon/> and this<https://fawnoos.com/2021/03/02/cas64-saml2-metadata-caching/>.

Has anyone configured such a setup or is aware of how we might proceed in such a case?
