The same happens with tcsh. New shells such as tcsh (and presumably
zsh) set the environment variable PWD to the current directory. This
is a nice feature if you got to the current directory by traversing a
symbolic link (which is the case if the directory has been
automounted).

Old-fashioned shells, such as /bin/sh and /bin/csh don't know about
this feature and don't neither change nor remove the variable. Good
programs such as emacs honor the contents of PWD (but they should
probably make some sanity checks on the contents).

The easiest way to solve it is to put the line
	unsetenv PWD
in the .cshrcs of the accounts you /bin/su to.
