The main purpose of "nscd" for example is to cache user objects and I'm
pretty sure several other higher level services are doing as well. 
Think of a busy website authenticating against LDAP, without cache
they'd easily overload their directory service.

In order to reflect password changes they just need to look up the last
changed timestamp every once in a while, but not the entire user
object.

Didn't see that one before (too many unread emails), will try to stick
to it.
