|System Administration Guide: Naming and Directory Services (NIS+)|
Whenever you change any server's keys, you must update all of the clients as well. Remember, that all NIS+ servers are also NIS+ clients, so if you update the keys on one server, you must update key information on all other machines in the domain regardless of whether or not they are NIS+ servers or ordinary clients.
There are three ways to update client key information:
Another way to update an individual client's key information is by running the nisinit command on the client as described in Three Methods to Initialize an NIS+ Client.
You can globally update client key information for all the machines in a domain by shortening the Time To Live value of the domain's directory object as explained in Globally Updating NIS+ Client Key Information.
For example, if you have changed the keys for a server in the sales.doc.com. domain, to reduce the directory's TTL value to one minute you would enter:
client% nischttl 60 sales.doc.com.
For example, to reset the TTL value to 12 hours for the sales.doc.com. domain's directory object, you would enter:
client% nischttl 12h sales.doc.com.
See nischttl Command for more information on working with TTL values.
