LocalDynamicMetadataProvider fetches metadata from a local source dynamically as needed. The deployer is responsible for populating the local source with data, which may be done while the metadata provider is running. New metadata will be seen automatically the first time it is requested.
|title||Use this provider with local metadata|
FilesystemMetadataProvider was added in v3.3.0. It is used with local metadata. See the MetadataManagementBestPractices topic for more information.
A common use case will be to use a filesystem directory as the local source. A convenience attribute
sourceDirectory is supplied to facilitate this configuration. In this case, the deployer adds XML files each containing a single
<md:EntityDescriptor> element to the
sourceDirectory. By default, when using the
sourceDirectory the file naming convention will be the lower case hex-encoded SHA-1 digest of the
entityID, suffixed with ".xml". For example, the metadata for the entity with
entityID "urn:test:foobar" will be resolved from the
sourceDirectory with filename "d278c9975472a6b4827b1a8723192b4e99aa969c.xml".
Note that with the default
entityID digest mechanism, the digested value should not include any leading or trailing whitespace (in particular, no trailing new line character):

<MetadataProvider> element and the type
LocalDynamicMetadataProvider are defined by the
urn:mace:shibboleth:2.0:metadata schema, which can be located at http://shibboleth.net/schema/idp/shibboleth-metadata.xsd.
Any of the Common Attributes or the Dynamic Attributes may be configured. In addition, the following attributes are available on a
Convenience mechanism for wiring a
FilesystemLoadSaveManager, loading from the specified source directory in the local filesystem. This attribute will be ignored if
sourceManagerRef is also specified. Either this attribute or
sourceManagerRef is required.
|Bean ID||Identifies the Spring bean for the |
XMLObjectLoadSaveManager which serves as the local source of metadata. Either this attribute or
sourceDirectory is required.
|Bean ID||internal default instance||Identifies a Spring bean for a |
Function which generates the string key used with the
XMLObjectLoadSaveManager. The internal default implementation produces the lower-case hex-encoded SHA-1 digest of the entityID of the input criterion. If the manager was effectively specified via
sourceDirectory, then the internal default implementation suffixes this source key with ".xml".
|title||The source directory and the cache directory must be distinct|
sourceDirectory and the
persistentCacheManagerDirectory (if any) must be distinct. While it is possible, though probably unusual, to enable persistent caching of local metadata, do NOT rely on the same directory for both the source and the cache. This would cause the removal of cached metadata to actually remove the underlying metadata from your system.
Any of the following child elements may be specified (in order).
