net vampire - error

I am trying to join a running samba4 server: 

./net vampire gbg.inputinterior.se -Uadministrator
--realm=gbg.inputinterior.se
Password for [GBG.INPUTINTERIOR.SEadministrator]:
CLDAP response: forest=gbg.inputinterior.se dns=gbg.inputinterior.se
netbios=GBG server_site=Default-First-Site-Name
client_site=Default-First-Site-Name
libnet_BecomeDC() failed - NT_STATUS_INVALID_NETWORK_RESPONSE
Traceback (most recent call last):
 File
"/usr/local/samba/lib/python2.5/site-packages/samba/netcmd/__init__.py",
line 99, in _run
 return self.run(*args, **kwargs)
 File
"/usr/local/samba/lib/python2.5/site-packages/samba/netcmd/vampire.py",
line 51, in run
 (domain_name, domain_sid) = net.vampire(domain=domain,
target_dir=target_dir)
RuntimeError: NT_STATUS_INVALID_NETWORK_RESPONSE 

Any that can give me an idea howto find out what I am doing wrong? 

Both servers are runnning: Version 4.0.0alpha14-GIT-10adee8 

On the new server I just did "make install" no provision.
