Because su needs suid permissions to be able to set the uid to the one
you are wanting.

Have you run some sort of hardening script that removes suid/guid bits
from scripts/programs on your system (such as bastille?) - this will
remove normal user functionality from programs such as ping etc.

Running su under sudo would have worked fine as you were running su as
root and not as you.
