I will bring this point up to my web admin though in the past there were
reasons for this.
Possibly due to permissions on other facets of the entire system, not
just the web component. We are running Apache on Windows, with a very
limited set of user accounts, no NT domain, all administrator user
accounts on the servers only. I know there are other alternatives to
this infrastructure, though this is what was working with the older
Condor. (In other words I promised my team that an upgrade to condor
6.6.1 would not incur any changes on the rest of the system and can all
be handled on the Condor end, but I was simply mistaken.)

If you don't post the patch, please send it to me. That would be helpful
for more
Than this situation.

I'll rehash the issue with 1) and investigate 2).
You guys are the best, thanks for your help and I'll investigate this
