I'm trying to isolate execute nodes by specific users using START expressions. e.g., . I did one simple test , which appears like another user cannot hijack another Owner's name. Are there any other security implications I should be thinking of?
START = (Owner == "mkandes")
 emfajard@pcf-osg ~$ condor_qedit 11676.0 Owner mkandes
