Sorry, it appears that I was wrong about the role of caching.  Our
cluster nodes (running CentOS) have this nscd config:

--8<---------------cut here---------------start------------->8---
enable-cache passwd yes
enable-cache group yes
enable-cache hosts no
enable-cache netgroup no
--8<---------------cut here---------------end--------------->8---

So while we don’t rely on caching per se, nscd needs to be configured to
cache passwd and group so that it actually fetches this type of
information from the system directories (e.g. LDAP).

Sorry for the confusion!
