This is a two step process:
1) Add the server to the NIS domain
2) Make sure none of the uid's on the server conflict with NIS,
because the local uid's typically have precedence
To add the server to the NIS domain:
1) make sure ypbind is installed
2) domainname YOUR_NIS_DOMAIN_NAME
3) add 'domain YOUR_NIS_DOMAIN_NAME server NIS_SERVER_ADDR' to /etc/yp.conf
4) service ypbind start
To make that permanent, make sure ypbind starts up on boot
chkconfig --level 345 ypbind on
Then tell the initscripts about your domain name
echo "NISDOMAIN=YOUR_NIS_DOMAIN_NAME" >> /etc/sysconfig/network
BTW: Your NIS domain name is completely different, semantically, from
your DNS domain, but sometimes they are set to the same string.
