This of course will reflect in a change of the corresponding entry within the local.meta
The next step would be giving away the owner rights of the saved search, beeing an ordinary user. Unfortunately this can not be done:
curl -k -u user:changeme -d 'owner=foo' -d 'sharing=app' https://localhost:8089/servicesNS/user/search/saved/searches/myTestSearch/acl
ERROR: In handler 'savedsearch': You do not have permission to change the owner of this object.
Is there any other way to accomplish this? Maybe a dedicated capability (not admin_all_objects)?
