Can JobManager do that as it should have the creator information when the job 
is being created?

Thanks,

Hello Carsten

Thanks for your reply.

No, I don't see an obvious solution either.
It's just that while reviewing the loginAdmin() usages, I discovered that a lot 
of the cases are based on this problem, and I was hoping for a solution that is 
as generic as possible.

For the jobs, I could imagine an extension of the JobManager API that allows 
passing the subject. The resource resolver factory could then take the 
event/job as a parameter and return a resolver with the privileges of the 
corresponding subject.

For the events, the situation seems to be even more complicated because usualy 
the event is not created manually, and I'm not sure if it is possible to assign 
a specific subject to an event in many cases.

The alternative is to use a service-user in the consumer who has access to the 
respective payload, which somehow looks wrong to me from a security perspective.

Well.. Ideas very welcome :)

Best greetings
Lars
