[Samba] Migration: Failed to setup BDC creds

[ksun at ABINITIO.COM]

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:
