I have the latest (as of 1/25/11) git of samba-master but I have been getting some wierd errors when trying to join it. At first I was getting an NT_STATUS_INTERNAL_ERROR then I saw a previous post by someone with the exact same problem at http://lists.samba.org/archive/samba-technical/2010-December/075431.html So I applied Kamen's patch (http://lists.samba.org/archive/samba-technical/2010-December/075479.html) and I was able to get much farther this time.

(error due to msExchBridgeheadedLocalConnectorsDNBL being single valued,
by having multiple values)

However I don't have the net vampire tool anymore as this is a later git and it has apparently been removed and replaced with "samba-tool join".

Eric and Stephan, 

I've worked with tridge to add a workaround for what we think is a
broken schema from Microsoft.  Our guess is that the single-value checks
are not applied to backlinks, and so we now skip them in Samba4.

The fix is in master after a6af1efb422e10bb66524fdceb2babaa8ca1bffe, can
you try again with current master if you are able?  It would be good to
confirm that this is fixed if at all possible. 

Thanks,

Andrew Bartlett
