[galaxy-dev] Submitting jobs with PBS

Hi !! I've got a problem with PBS when I want to submit a job to our cluster with Galaxy. Every time, PBS says me "pbs_submit failed, PBS error 15023: Bad user - no password entry". Indeed, Galaxy uses my email address (used in Galaxy) as user by default ! But, before, when I used SGE on my previous lab, Galaxy used the galaxy owner user and not my email… Is it possible to set the owner user as previous Galaxy version ? (I found the "drmaa_external_*" session in universe but I don't really understand how to configure this part…). Thanks a lot, Best Regards BRAS Marc
