We just updated our configuratiosn to have multiple NIS servers, when we initiated a test of client failover, we were disapointed.
It seemed that the only way to get a filaover was to /etc/init.d/ypbind restart.
It behaves as indicated in http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=5084845 using ypbind-1.17.2-13 on Centos 4.5 / Linux xxxxxxxxxxxx 2.6.9-55.0.12.ELsmp #1 SMP Fri Nov 2 12:38:56 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux

Any advice?
Not one you want to hear: ditch NIS. It's known to have a *lot* of security holes. At the very least, NIS+. Better would be either RH directory server (which I've never worked with), or openLDAP (which is, IMO, NOT ready for prime time, but is built for security.
