Ok, then we rule out batch machines where there are no user
credentials. NFS does this fine. I know this is REALLY ugly,
but I have customers who need this. If you have a good
solution for that problem, I would really be happy to hear
this. Something like constrained delegation in Kerberos to
me sounds pretty much like the exact same hack in a
different place.
