It is likely that when you moved the file you lost the original
ownership and permission of the file.  It needs to be owned by root
and suid-root in order to function.  You will need to be root to
perform the fix if that is the problem.

  chown root:root /bin/su
  chmod 04755 /bin/su
  ll /bin/su
  -rwsr-xr-x    1 root     root        14184 Jul 12  2000 /bin/su
