  NFS-mount critical/shared files.  This has the following tradeoffs...

advantages: it's 
	substantially faster
	very visible (ie, you do a mount and see where something comes from)
	reliable
	secure as nfs (which isn't anything to write home about...)
	widely supported (much more than yellow pages)
disadvantages: it's
	a single point of failure (fallback is easy, though)
	dependant on NFS semantices (not unix semantics), and
	necessary to write your own passwd/chsh/chfn/mkuser
