It should be.  If NISDOMAIN isn't set in /etc/sysconfig/network or
/etc/sysconfig/ypbind, then the ypbind script looks for it by scanning
/etc/yp.conf for an uncommented line beginning with "domain" (it can be
any of the three "domain"-type lines).  A client, by definition, has to
run ypbind.

Have a looksee at /etc/rc.d/init.d/ypbind for details.
