it seems crazy that it would take that long to return a handful of
records.  My seat of the pants tells me it's not an ldap issue at all,
but a network problem, like a nameserver timeout, or somesuch.  If you
have the same problem on localhost, that would shoot down yet another of
my bright ideas.

Watch the network traffic with something like

tcpdump -q -n -l host <clientip> and host <serverip>

to watch traffic between the two machines.  Does it stall before the
conversation even starts?  Or does it stall after the client asks a
question and before the server answers?
