[Samba] Importing accounts from NT4 domain with Vampire

[Filipe]

Hi
I have folowed this guide 
http://www.enterprisenetworkingplanet.com/netos/article.php/3457461 to 
import users from my NT4 domain to a debian sarge with samba 3.0.14a
Everything runs fine till the net rpc vampire command, some users give 
an error others are imported fine.
I don't see any problem on this users configuration in the NT4 server, 
here is part of the output:
thanks.

fb_nt2:/etc/samba# net rpc vampire -S fb_nt -W FFTBL -UFilipe%*****
