SAML2 Delegated Authentication

CAS can be configured to route the authentication requests to one or more external SAML2 identity providers. Support is enabled by including the following dependency in the WAR overlay:

Configuration

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.

  • cas.authn.pac4j.saml[0].keystore-password=
  • The password to use when generating the SP/CAS keystore.

    org.apereo.cas.configuration.model.support.pac4j.saml.Pac4jSamlClientProperties.

    How can I configure this property?

    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. In other words, you should only include this field in your configuration if you need to modify the default value or if you need to turn on the feature controlled by the setting.

  • cas.authn.pac4j.saml[0].accepted-skew=PT300S
  • Maximum skew in seconds between SP and IDP clocks. This skew is added onto the NotOnOrAfter field in seconds for the SAML response validation.

    How can I configure this property?

  • cas.authn.pac4j.saml[0].maximum-authentication-lifetime=PT3600S
  • Once you have an authenticated session on the identity provider, usually it won't prompt you again to enter your credentials and it will automatically generate a new assertion for you. By default, the SAML client will accept assertions based on a previous authentication for one hour. You can adjust this behavior by modifying this setting. The unit of time here is seconds.

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

You may choose org.pac4j.saml.store.HttpSessionStore instead which allows SAML messages to be stored in a distributed session store specially required for high availability deployments and validation operations.

    Available options are:
    • EMPTY: Uses the EmptyStoreFactory
    • SESSION: Uses the HttpSessionStore
    • Fully-qualified class name of the message store implementation.

    Also note that the message store implementation can be supplied and configured at runtime as a Spring @Bean with the type SAMLMessageStoreFactory which, if found in the available application context, will override all other options.

    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.

    Be Selective

    This section is meant as a guide only. Do NOT copy/paste the entire collection of settings into your CAS configuration; rather pick only the properties that you need. Do NOT enable settings unless you are certain of their purpose and do NOT copy settings into your configuration only to keep them as reference. All these ideas lead to upgrade headaches, maintenance nightmares and premature aging.

    YAGNI

    Note that for nearly ALL use cases, declaring and configuring properties listed here is sufficient. You should NOT have to explicitly massage a CAS XML/Java/etc configuration file to design an authentication handler, create attribute release policies, etc. CAS at runtime will auto-configure all required changes for you. If you are unsure about the meaning of a given CAS setting, do NOT turn it on without hesitation. Review the codebase or better yet, ask questions to clarify the intended behavior.

    Naming Convention

    Property names can be specified in very relaxed terms. For instance cas.someProperty, cas.some-property, cas.some_property are all valid names. While all forms are accepted by CAS, there are certain components (in CAS and other frameworks used) whose activation at runtime is conditional on a property value, where this property is required to have been specified in CAS configuration using kebab case. This is both true for properties that are owned by CAS as well as those that might be presented to the system via an external library or framework such as Spring Boot, etc.

    :information_source: Note

    When possible, properties should be stored in lower-case kebab format, such as cas.property-name=value. The only possible exception to this rule is when naming actuator endpoints; The name of the actuator endpoints (i.e. ssoSessions) MUST remain in camelCase mode.

    Settings and properties that are controlled by the CAS platform directly always begin with the prefix cas. All other settings are controlled and provided to CAS via other underlying frameworks and may have their own schemas and syntax. BE CAREFUL with the distinction. Unrecognized properties are rejected by CAS and/or frameworks upon which CAS depends. This means if you somehow misspell a property definition or fail to adhere to the dot-notation syntax and such, your setting is entirely refused by CAS and likely the feature it controls will never be activated in the way you intend.

    Validation

    Configuration properties are automatically validated on CAS startup to report issues with configuration binding, specially if defined CAS settings cannot be recognized or validated by the configuration schema. Additional validation processes are also handled via Configuration Metadata and property migrations applied automatically on startup by Spring Boot and family.

    Indexed Settings

    CAS settings able to accept multiple values are typically documented with an index, such as cas.some.setting[0]=value. The index [0] is meant to be incremented by the adopter to allow for distinct multiple configuration blocks.

    Metadata Management

    Please see this guide.

    Per Service Customizations

    Th configuration for the external SAML2 identity provider is typically done at build time via CAS configuration settings and applies to all applications and relying parties. You may override certain aspects this configuration on a per application basis by assigning dedicated properties to the service definition.

    The following properties are available and recognized by CAS for various modules and features:

    Name Default Value Type Group
    forceAuthn BOOLEAN DELEGATED_AUTHN
    passiveAuthn BOOLEAN DELEGATED_AUTHN
    AuthnRequestBindingType STRING DELEGATED_AUTHN_SAML2
    AssertionConsumerServiceIndex LONG DELEGATED_AUTHN_SAML2
    AttributeConsumingServiceIndex LONG DELEGATED_AUTHN_SAML2
    ComparisonType STRING DELEGATED_AUTHN_SAML2
    NameIdPolicyFormat STRING DELEGATED_AUTHN_SAML2
    NameIdPolicyAllowCreate BOOLEAN DELEGATED_AUTHN_SAML2
    ProviderName STRING DELEGATED_AUTHN_SAML2
    IssuerFormat STRING DELEGATED_AUTHN_SAML2
    UseNameQualifier BOOLEAN DELEGATED_AUTHN_SAML2
    AuthnContextClassRefs SET DELEGATED_AUTHN_SAML2
    NameIdAttribute STRING DELEGATED_AUTHN_SAML2
    WantsAssertionsSigned BOOLEAN DELEGATED_AUTHN_SAML2
    WantsResponsesSigned BOOLEAN DELEGATED_AUTHN_SAML2
    MaximumAuthenticationLifetime LONG DELEGATED_AUTHN_SAML2
