Samba authentication problem in NT Domain

[Andrea Zennaro]

Well, I would like to share the resuorces of my linux Box in an NT Domain.

Using the "smbpasswd -j INFOTECH -r NT_PDC" command line I am able to join
the domain INFOTECH where the NT_PDC is the PDC running NTServer 4 Sp4.

I have add the samba server in the Server Manager and I have set up the the
same user account in both the NT Domain and the samba server.

At this point starting nmbd and smbd I can find the linux box on the
"Network Neighborhood" but when I try to browse it the Windows machine
prompt me for username/password. There is no way to be authenticated.

If I add the user password in the smbpasswd file everything work
BUT why I can be authenticated by the PDC ?
