samba - Jul 2004 - Migration: Failed to setup BDC creds

Greetings
        I configured a BDC with Samba 3.0.3. When I try to synchronize it 
with a PDC using 
        "net rpc vampire -Uadministrator%password"
        I got "Failed to setup BDC creds".
        With deugger on the got the following information:

        What went wrong?

        Thanks!

I figure that out.
  You actually not suppose to start samba while doing hte migration. net 
rpc vampire will just read the configuration file and figure out where is 
the backend.
 Chapter 8 of "Samba-3 by Examples" has detailed procedure.
