I only received a few replies and the final answer appears to be
that credentials are not propagated and you would have to
write your own system to make it happen.

However, SUN have a new product in the pipeline called SEAM which
will (I hope) address my problem as well as a few other security
issues. SEAM will be part of Solstice Enterprise Manager.
Some information on SEAM is available on the SUN website.
Release is slated for mid year.

Many thanks to those who replied.
