At least Solaris 2.5, 2.5.1 and 2.6 has a feature (bug?) that
porhibit processes from creating a core-dump with abort() if
they has ever changed its uid.

The problem with this is that SAMBA often changes uid. So the
possibility for a core is realy small. But it the need
for a way to debug thouse situatuins is still there.

I have created a script that I spawn with "panic action"

panic action = "/opt/fw/samba/bin/panic.sh >> /var/log/samba_panic.log"

But there is a problem, this script is executed as the uid that
SAMBA where executing as at the time of the crash. So I would
like this patch to go into SAMBA that sees to it that "panic action"
is allways called as root.
