Thanks for your solution. I also have a very similar problem - in my case, a
simulation daemon that submits all jobs as the same user.
While the project accounting approach will work for this one simulation
daemon, I dread enforcing a project for all the other possible ways of
accessing the gridengine.

I was wondering about this possible alternative:

I let the simulation daemon run with the same UID/GID as the gridengine
admin_user.  Noting that this admin_user is a pure administrative user with
sge manager/operator rights, and *only* submits any jobs as a proxy, I would
naively think that this manager/operator user should be allowed to jiggle
with the bookkeeping internals to tag the job accounting (including
fairshare) as being booked for the 'real' user.

Is there a backdoorish way to manage this, or should I try with a RFE?
