Date: 25 Jan 1995 16:44:13 GMT Organization: Imperial College, Dept of Mechanical Engineering Message-ID: <3g5v4t$i04@ccserver.cc.ic.ac.uk> X There appears to be a problem with NIS automount maps which include file maps. According to the IRIX 5.3 documentation this should work, however, when you include a map in a file from within a NIS map it sometimes gets ignored. Silicon Graphics are aware of this problem. X Here is a work-around script for the problem. It works by creating a directory to store copies of the NIS maps in with correctly modified sub-map entries. As it stands it will only work with the default NIS auto.master master map although it should be fairly easy to modify it to work with other master maps. It is designed to be used from a crontab to keep the files updated with the latest NIS configuration. X WARNING: DO NOT USE THIS SCRIPT UNLESS YOU RUN INTO THE NIS MAP PROBLEM AND KNOW WHAT YOU ARE DOING. IT COULD MESS UP YOUR AUTOMOUNT CONFIGURATION.
