if your frontend is the only access your users have to the cluster, you can
enforce the concept of different "users" at that level. however, if your end
users have the ability to actually run condor_submit, condor_q, and condor_rm,
etc. and talk directly to the condor_schedd, this will not work.
for example, say you have a web frontend running on some machine with a schedd.
that frontend can insert extra attributes into the job by putting something
like this in the submit file:
+webuser = zmiller
then the frontend can use the -constraint option to the condor tools to do
things on behalf of the webuser. the web frontend is also responsible for
authenticating that user somehow, probably a password.
i'm not sure if this is what your were asking for... if not, sorry!
