I think you're misreading the output there.  You have two directories
controlled by autofs (/local and /home), and one of them has had a
directory mounted under it (/home/max, under /home).  None of these is
mounted twice.

This test checks for an entry for the user "nobody" in your passwd map.
If your network isn't expected to have one in NIS (i.e., if "nobody" is
a local user whose information is stored in /etc/passwd and
/etc/shadow), then it's not an error.

The real purpose of the test is to exercise functionality used by
ypmatch (and other NIS-aware software, such as libc).  The specific map
and key names are arbitrary, and can be specified to yptest on the
command line (see the man page for details).
