Yes indeed.

The SysAdmin started condor when he/she was logged in as user condor.
To get privilege switching, you have to start condor as root.  The
condor daemons will have a 'real' uid of root, but change to user condor
most of the time for safety's sake.  If the condor master was started as
user condor, then you'll always be user condor: this is what you're

It _almost_ did the trick.  The master re-execs itself, so it still
doesn't gain root privs.

Solution A: Make your in/out/err files writ[e]able by user condor.  
Solution B: Ask the sysadmin to start condor as user root everywhere.
Solution C: (Assuming the sysadmin won't have a problem with this) 
#1 condor_config_val master  (to find out where the condor master is 
#2 condor off -master
#3 log in as root, then start the condor master using the path from #1

This will take care of one machine...

Hope this helps,
