SAML2 Metadata Management

The following CAS endpoints handle the generation of SAML2 metadata:

  • /idp/metadata

This endpoint will display the CAS IdP SAML2 metadata upon receiving a GET request. If metadata is already available and generated, it will be displayed. If metadata is absent, one will be generated automatically. CAS configuration below dictates where metadata files/keys will be generated and stored.

Note that the endpoint can accept a service parameter either by entity id or numeric identifier. This parameter is matched against the CAS service registry allowing the endpoint to calculate and combine any identity provider metadata overrides that may have been specified.

The following settings and properties are available from the CAS configuration catalog:

The configuration settings listed below are tagged as Required in the CAS configuration metadata. This flag indicates that the presence of the setting may be needed to activate or affect the behavior of the CAS feature and generally should be reviewed, possibly owned and adjusted. If the setting is assigned a default value, you do not need to strictly put the setting in your copy of the configuration, but should review it nonetheless to make sure it matches your deployment expectations.

The configuration settings listed below are tagged as Optional in the CAS configuration metadata. This flag indicates that the presence of the setting is not immediately necessary in the end-user CAS configuration, because a default value is assigned or the activation of the feature is not conditionally controlled by the setting value.

  • cas.authn.saml-idp.metadata.core.cache-expiration=PT24H
  • How long should metadata be cached.

    This settings supports the java.time.Duration syntax [?].

    Configuration Metadata

    The collection of configuration properties listed in this section are automatically generated from the CAS source and components that contain the actual field definitions, types, descriptions, modules, etc. This metadata may not always be 100% accurate, or could be lacking details and sufficient explanations.
