Password maps in standard YP are insecure, because the pw_passwd
field is accessible by any user. A common solution to this is to
generate a secure map (using
``makedbm -s'')
which can only be accessed by a client bound to a privileged port.
To activate the secure map, see the appropriate comment in
/var/yp/Makefile.yp
.
The
NIS
subsystem is conditionally started in
/etc/rc
.
See the
/etc/rc.conf
file for configuration variables.
The `secure map' feature is not compatible with non-BSD implementations as found e.g. in Solaris.
