Yes. NetBSD does it. A user can only get /etc/passwd respectively the
passwd.byname map with ypcat. /etc/master.passwd respectively the
master.passwd.byname map is only reachable via reserved ports. So ypcat
must run with root permissions to get the master.passwd.byname map. I
dont know exactly, but I think this is a special *BSD feature.

Sure. But the wall is higher in the last case.

BTW: What is Kerberos? Is there a FAQ? There is somthing in
/etc/inetd.conf, but there is no /usr/libexec/kpasswdd, no man pages,
