That message gets printed whenever a remote NIS client tries to access
master.passwd.* over a non-privileged port.  Only root should have
access to the master maps, so a remote process has to bind to a port <
1024 before doing the lookup, to prove that it's root.  It looks like
for some reason you have a process that's running as root but is using
a port over 1024.  I can't see anyplace in the NIS client code that
binds the socket, though, so I must be looking in the wrong place.  It
has to work, or else you wouldn't be able to log in using NIS at all.
