Given I am Jenkins administrator when I create a job like the following:
... I'm not able to answer the question it asks as I get an error saying "You need to be foobar to submit this" and I'm unable to stop/kill the job (it just doesn't work).
Probably there should be special permission for admins to stop such jobs and/or the plugin should check if the submitter is a real person when saving/running the job.
I'm using Jenkins ver. 1.596 and workflow plugin v1.1
