There's the interesting bit - the connection is rejected. If I now take
a bit more time to look back at your previous message :) then I see:

Aha! Both realservers have a weight of zero - the VIP, therefore, can't
handle any (new) requests. You have "quiescent=yes" which means if the
server is determined to be down, the weight is set to 0.
You need to determine why the servers look to be down. Can you connect
to the MySQL port on the realservers from the director using the same
connection details you have configured in ldirectord.cf?
