Issue Type: New Feature Affects Versions: 3.0.4 Assignee: Henri Mikkonen ( https://shibboleth.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A1614c4a5-c89e-4edc-9421-990bd6ea85fd ) Attachments: LocalDynamicClientInformationResolver.java Created: 25/Mar/22 2:28 PM Priority: Trivial Reporter: Simone Avogadro ( https://shibboleth.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A60a84ee1-4961-471b-99d8-f67c05e24403 )

Here attached is our implementation for a LocalDynamicClientInformationResolver which mimics the behaviour of the LocalDynamicMetadataProvider by allowing to place the RP metadata within a local folder and naming it according to the <sha-1(rp.client_id)>.json format

The main limitations are:

* it’s an adaptation on top of the FilesystemClientInformationResolver
* it does not perform garbage collection: unused/expired/deleted entries will stay there until anyone tries to access them

Here’s an example configuration:

<!-- 'metadata' must point to a folder, files will be searched in SHA-1 in the same folder as <SHA-1(ClientID)>.json -->
<bean id="DynamicFileResolver" class="com.mindmercatis.shibboleth.oidc.metadata.LocalDynamicClientInformationResolver"
   c:metadata="%{idp.home}/conf/dynamic-metadata-oidc/"
   p:maxCacheDuration="PT5M" 
   />

The file has the Apache 2.0 standard license header. We left the reference to Mind-Mercatis but obviously please replace it as needed
