[Samba] Problems connecting to samba with a valid user

[Popof Popof]

Hi,

I'm having some troubles with my samba configuration:

I'm running a FreeBSD 8 file server with samba version 3.2.15.
The port was compilated with WinBIND and UTMP support.

Samba is started by the /etc/rc.conf option: samba_enable="YES"
so that all smbd, nmbd and winbindd daemons are launched.

There is no fw on the box.

I used the smb.conf.default configuration file. I've just added log level =
3 and two shares definitions as following:

    [Data01]
        path = /mnt/Data01
        public = yes
        browseable = yes

    [Data02]
        path = /mnt/Data02
        valid users = Popof
        public = no
        browseable = yes

Popof is a valid user on system and I've created a password for samba using
smbpasswd -a Popof (using a different password than the system one (just in
case)).
root has also a valid account also created with smbpasswd.

Here is the output of pdbedit for Popof

    # pdbedit -v Popof

When I try to login from a client box on my server with user Popof using
smbclient (smbclient -U Popof -W MYGROUP -L <server_address>)
I get the following error in log files:

    [2010/04/09 16:59:07,  3] auth/auth.c:check_ntlm_password(220)

But if I use the same command without entering password (logged as nobody)
it works well.
Also I can acces the Data01 share with anonymous account but if I try to get
into Data02 the system asks me for a password and I get the same error.

Does anyone have any idea on what is wrong?
