Can you tell us what the original problem was Jon? First of all it was al=
l
chaos and doom in the openldap api. Now it's not. It was only yesterday
that you said a switch to jndi was essential. Now it's not?

Sounds like you may have sorted a problem with ad interfacing - would be
nice to know what it was.

What do you get if you turn on java.net.debug=3Dall?
Are you using sasl/tls etc?
