Yes, probably. Moreover, what it means to get the auth port for running a
setuid binary should be the very same thing it means to get the auth port
for running a translator.
I think the reasonable thing to do is something like, try an auth_makeauth
literally as requested; if that fails, try replacing the ids with the
filesystem process's or underlying node's ids.
