NameTypeDefaultDescription
parserPoolRefBean IDshibboleth.ParserPoolIdentifies a Spring bean for the (OpenSAML) ParserPool object XML parser used to parse incoming metadata. Generally should not be changed.
taskTimerRefBean ID
Identifies a Spring bean containing a Java TaskTimer used to schedule reloads. When not set, an internal timer is created. Generally should not be changed.
refreshDelayFactorReal Number (strictly between 0.0 and 1.0)0.75A factor applied to the initially determined refresh time in order to determine the next refresh time (typically to ensure refresh takes place prior to the metadata's expiration). Attempts to refresh metadata will generally begin around the product of this number and the maximum refresh delay.
minCacheDurationDurationPT10M (10 minutes)The minimum duration for which metadata will be cached before it is refreshed.
maxCacheDurationDurationPT8H (8 hours)The maximum duration for which metadata will be cached before it is refreshed.
maxIdleEntityDataDurationPT8H (8 hours)

The maximum duration for which metadata will be allowed to be idle (no requests for it) before it is removed from the cache.

removeIdleEntityDataBooleantrueFlag indicating whether idle metadata should be removed.
cleanupTaskInterval                          DurationPT30M (30 minutes)

The interval at which the internal cleanup task should run.  This task performs background maintenance tasks, such as the removal of expired and idle metadata.

persistentCacheManagerRef 3.3Bean ID
The optional manager for the persistent cache store for resolved metadata.  On metadata provider initialization, data present in the persistent cache will be loaded to memory, effectively restoring the state of the provider as closely as possible to that which existed before the previous shutdown.  Each individual cache entry will only be loaded if 1) the entry is still valid as determined by the internal provider logic, and 2) the entry passes the (optional) predicate supplied via initializationFromCachePredicateRef.
persistentCacheManagerDirectory 3.3File specification

The directory used for an internally-constructed filesystem-based persistent cache. This is a convenience parameter to avoid specifying a full bean via persistentCacheManagerRef. This option will be ignored if persistentCacheManagerRef is specified.

persistentCacheKeyGeneratorRef 3.3Bean IDinternal default instanceIdentifies a Spring bean for a Function which generates the string key used with the cache manager. The default implementation produces the lower-case hex-encoded SHA-1 digest of the entityID of the EntityDescriptor.
initializeFromPersistentCacheInBackground 3.3BooleantrueFlag indicating whether should initialize from the persistent cache in the background.  Initializing from the cache in the background will improve IdP startup times.
backgroundInitializationFromCacheDelay 3.3DurationPT2S (2 seconds)

The delay after which to schedule the background initialization from the persistent cache when initializeFromPersistentCacheInBackground=true.

initializationFromCachePredicateRef 3.3Bean IDan "always true" predicate

Identifies a Spring bean for an optional Predicate which determines whether a given entity should be loaded from the persistent cache at resolver initialization time.
