Yea, that not usually a message worth paying attention to. You'll see
that on all Condor installs regardless of what user the daemons are
Good to know.

It's the achilles heel of Windows-as-a-server: how do you run a daemon
on a machine that can access network shares but is still all powerful on
the local machine? Basically, you can't do this without making some
concessions. The concessions we've made at Altera are keeping a
wide-open, read-only share for Condor configuration files (so that a
damon run as SYSTEM can read it's configuration from a UNC path). And
then we use the VMx_USER settings so we don't have to worry about
synchronizing user password changes with the condor_credd server.
I suppose we'll end up doing something like this as well. Thanks for sharing.
We're seriously looking at VM Ware to make this daemon/permisison
headache a thing of the past. We'll run Linux on our entire farm and
Windows jobs will get run under VMs. We're still a ways off implementing
this but it's a promising solution to the Windows "server" management
headache we deal with now and all the hoop jumping we do to make the
pool easy to administer.
This is a really great idea! The only thing preventing me from trying this is that our windows machines are graphics workstations and VMWare (AFAIK) doesn't yet support graphics acceleration to the degree needed by computer animators.
I'd really love to hear how this works out whenever you get a change to start testing it.
