The problem with su just returning, saying sorry, is due to various problems
with the setcompat syscall in A/UX.
Basically when su runs it can't open /dev/tty, this is due to the shell not
running in the proper setcompat modes.
We run tcsh here, and now have no problems, but it was hell for a while.
The setcompat stuff is both confusing and DANGEROUS. Do not ever use the
COMPAT_EXEC option unless you are absolutely sure that you want the rest of
the world to work under you compat modes.
If you require further info please mail me directly.
