We are configuring OpenID Authorization Provider on 12.7 PS and the list of the available User Stores does not include the custom User Stores.

Is this expected behavior or is this a bug?
SSO 12.7
SSO 12.8
This behavior is expected as custom user stores are not supported with OpenID Authorization Provider.

Note: Custom directories are not supported.
