problems with samba as a PDC server

[Gustavo Rahal]

Hi

I am trying to configure a samba to be a PDC server on a small home 
network. Never did it, completely newbie in this area.
Well, I read some documentation about how to do this but it's not 
working. From a winXP machine I can access the shares on the server. 
WinXP prompts for the user and password and connects correctly. When 
trying to configure XP as part of the domain I get an error: "The user 
name could not be found". When I try to log in with a nonexisting user I 
get a different message. When trying to connect with a normal user (not 
set as admin on smb.conf) I get a "Access is denied" message. So it 
seems like the users are been correctly identified by the server. I'm 
using fedora core 1 with samba 3.0.2rc1 (upgraded in hope that would 
work with the latest version)

Thanks
Gustavo

Here goes my smb.conf:
