+Patch and bits for linux yp/nis server to handle
+netbsd clients (maybe *bsd?)
+
+The problem is linux uses shadow, netbsd uses master.passwd
+and they are different formats. This generates a master.passwd
+file from the linux info. It requires perl and Class::Date to
+be installed.
+
+It tries to handle expiration/password change but it probably
+doesn't work (I havent tested it).
+
+Install -
+
+stick master-passwd.pl in /var/yp
+make sure its output looks right:
+
+./master-passwd.pl /etc/passwd /etc/shadow
+
+patch /var/yp/Makefile and then you should
+be good to go!
+
+take care
+/rex.
