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?
