Re: [HTCondor-users] write and execute from different computer in grid

[Bob Ball <ball@xxxxxxxxx>]

Change the uid/gid?  Not easily.  In my experience, to get this right, 
the simplest way is to uninstall condor, change the uid/gid to what you 
want it to be, then re-install.

You should sync the rest of the uid/gid that will be used as well.
