SAML2 Delegated Authentication - Metadata Management

In the event that CAS is configured to delegate authentication to an external identity provider, the service provider (CAS) metadata as well as the identity provider metadata automatically become available at the following endpoints:

Endpoint Description
/sp/metadata Displays the service provider (CAS) metadata. Works well if there is only one SAML2 IdP is defined.
/sp/idp/metadata Displays the identity provider metadata. Works well if there is only one SAML2 IdP is defined. Accepts a force=true parameter to reload the identity provider’s metadata.
/sp/{clientName}/metadata Displays the service provider metadata for the requested client name.
/sp/{clientName}/idp/metadata Displays the identity provider metadata for the requested client name. Accepts a force=true parameter to reload the identity provider’s metadata

Note that you can use more than one external identity provider with CAS, where each integration may be done with a different set of metadata and keys for CAS acting as the service provider. Each integration (referred to as a client, since CAS itself becomes a client of the identity provider) may be given a name optionally.

Remember that the service provider (CAS) metadata is automatically generated once you access the above endpoints or view the CAS login screen. This is required because today, generating the metadata requires access to the HTTP request/response. In the event that metadata cannot be resolved, a status code of 406 - Not Acceptable is returned.

Strategies

SAML2 metadata for both the delegated identity provider as well as the (CAS) service provider can managed via the following settings.

  • 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].metadata.identity-provider-metadata-path=

    • The metadata location of the identity provider that is to handle authentications. The location can be specified as a direct absolute path to the metadata file or it may also be a URL to the identity provider's metadata endpoint.

    org.apereo.cas.configuration.model.support.pac4j.saml.Pac4jSamlClientMetadataProperties.

    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.

    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.

  • Default

    SAML2 metadata for CAS as the SAML2 service provider is typically managed on disk, and generated on startup if the metadata file is not found. Future and subsequent changes to this metadata file, if necessary, must be handled manually and the file might need to be curated and edited to fit your purposes.

    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.

  • cas.authn.pac4j.saml[0].metadata.service-provider.jdbc.pool.max-wait=PT2S

    • Sets the maximum time in seconds that this data source will wait while attempting to connect to a database.

    A value of zero specifies that the timeout is the default system timeout if there is one; otherwise, it specifies that there is no timeout.

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

    How can I configure this property?

  • cas.authn.pac4j.saml[0].metadata.service-provider.jdbc.pool.maximum-lifetime=PT10M

    • This property controls the maximum lifetime of a connection in the pool. When a connection reaches this timeout, even if recently used, it will be retired from the pool. An in-use connection will never be retired, only when it is idle will it be removed.

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

    How can I configure this property?

  • cas.authn.pac4j.saml[0].metadata.service-provider.jdbc.ddl-auto=

    • Hibernate feature to automatically validate and exports DDL to the schema. By default, creates and drops the schema automatically when a session is starts and ends. Setting the value to validate or none may be more desirable for production, but any of the following options can be used:

    • validate: Validate the schema, but make no changes to the database.
    • update: Update the schema.
    • create: Create the schema, destroying previous data.
    • create-drop: Drop the schema at the end of the session.
    • none: Do nothing.

    Note that during a version migration where any schema has changed create-drop will result in the loss of all data as soon as CAS is started. For transient data like tickets this is probably not an issue, but in cases like the audit table important data could be lost. Using `update`, while safe for data, is confirmed to result in invalid database state. validate or none settings are likely the only safe options for production use.

    org.apereo.cas.configuration.model.support.pac4j.saml.Pac4jSamlServiceProviderMetadataJdbcProperties.

    How can I configure this property?

  • cas.authn.pac4j.saml[0].metadata.service-provider.jdbc.fail-fast-timeout=

    • Set the pool initialization failure timeout.

    • Any value greater than zero will be treated as a timeout for pool initialization. The calling thread will be blocked from continuing until a successful connection to the database, or until the timeout is reached. If the timeout is reached, then a PoolInitializationException will be thrown.
    • A value of zero will not prevent the pool from starting in the case that a connection cannot be obtained. However, upon start the pool will attempt to obtain a connection and validate that the connectionTestQuery and connectionInitSql are valid. If those validations fail, an exception will be thrown. If a connection cannot be obtained, the validation is skipped and the the pool will start and continue to try to obtain connections in the background. This can mean that callers to DataSource#getConnection() may encounter exceptions.
    • A value less than zero will not bypass any connection attempt and validation during startup, and therefore the pool will start immediately. The pool will continue to try to obtain connections in the background. This can mean that callers to DataSource#getConnection() may encounter exceptions.
    Note that if this timeout value is greater than or equal to zero (0), and therefore an initial connection validation is performed, this timeout does not override the connectionTimeout or validationTimeout; they will be honored before this timeout is applied. The default value is one millisecond.

    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.

    The table structure and schema needs to be created and must exist prior to CAS starting up, and it should be modeled after the following SQL statement:

    

    1

    		

    CREATE TABLE <table-name> (entityId VARCHAR(512), metadata TEXT)
