I have a small problem but one that is causing me some grief. After logging in to local console (serial port) as root, I need to telnet into the platform and then su root to continue testing. Simple enough right, having done this a million times on *nix

Or is it?  having created a user account to telnet in, I can login OK, but then attempting to su returns the following error:

-sh-2.05b$ su - root
su: cannot set groups: Operation not permitted

I've checked permissions on /etc/passwd, /etc/group

added suid sgid to busybox
chmod u+s /bin/busybox
chmod g+s /bin/busybox

but no luck so far.  kudos to the expert who can solve this one!
