21.3.7 Credential Setup

21.3.7.1 Root Master

1. Login as root on the root master server and create the credential for the root master at the highest security level
# nisaddcred des

Create the group nisadmin and the master host to the group
# nisgrpadm -c nisadmin.acs.ohio-state.edu.
# nisgrpadm -a nisadmin.acs.ohio-state.edu. master_host_name.acs.ohio-state.edu.

Update the NIS+ keys
# nisupdkeys acs.ohio-state.edu.
# nisupdkeys org_dir.acs.ohio-state.edu.
# nisupdkeys groups_dir.acs.ohio-state.edu.

Kill and restart the rpc.nisd with the new security level enforced
# ps -ef | grep rpc.nisd
# kill rpc.nisd_pid_number
# rpc.nisd -r

Set the permissions and group ownerships for the directories
# nischmod g=rmcd acs.ohio-state.edu. org_dir.acs.ohio-state.edu. groups_dir.acs.ohio-state.edu.
# nischgrp nisadmin.acs.ohio-state.edu. acs.ohio-state.edu.

Set the environmental variable NIS_GROUP. To do this permanently add this variable to /.profile and /.login, e.g.
# setenv NIS_GROUP nisadmin.acs.ohio-state.edu.
