That is expected because NT4 is a PDC and therefore believes it is
authoritative for all authentication. It will not pass the authentication
request through to Samba.

The vampire process registers the Samba server as a BDC. But you have to
update it to PDC. The NT4 PDC still thinks your Samba server is a BDC and
is looking for it to announce itself as such. Since it did not get the
message that says, "Hi, I'm your friendly BDC" it should show a ghosted
connection. ie: Grey icon that looks like any other domain member. The
greyed out icon could show in color, but it will never show as more than a
domain member machine.

Ok. I'd need to see the network traces to see what's going on.

You need an Administrator account in LDAP and it must have UNIX uid=0.

Look on the bright side: at least something is happy.

Ok, above.

I'd order the painters off site if I knew they would listen. How dare they
get in the way of your enjoyment. :)
