Try changing to a different directory. The error message is telling you that
you do not have permission (read? execute?--I forget what you need) for the
previous directory (..). For some reason, su needs to access every directory
in your current path to be able to access the /etc/passwd file (added
security?). Changing directories, or adding permission to directories in
your path should fix the problem.
