Ill try both when I get back to the computer. But there are no bugs or
limitations regarding mysql that would not allow this to work?

Indeed it is weird.
All I can think of is: Any difference putting the 'service=mysql' line
under the 'real=...' lines? (probably not), and... What does the
ldirectord log say when you start ldirectord?
Also, with tcpdump on the real servers active, does it register packets
when you telnet to port 3306 from the director (just to check that
tcpdump is working)?
