samba - Oct 2013 - ENC: Problems with public sharing on samba4

Hello guys,

I got a really annoying problem with public sharing on samba4. Here
what's happening:
I installed the samba4 packet on a Debian (3.5.0-42-generic). After that
I edited the /etc/samba/smb.conf as follows:

 

[global]

       workgroup = WORKGROUP

        netbios name = dc-000-051

        security = user

        map to guest = Bad User

        guest account = www-data

        socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65535
SO_SNDBUF=65535 SO_KEEPALIVE

        disable netbios = yes

        dns proxy = no

        default case = lower

        guest ok = yes

        guest only = yes

        strict sync = no

        sync always = no

        syslog = 1

        syslog only = yes

        load printers = no

        debug timestamp = yes

        hosts allow = ALL

        # Debug Logging Information

        log level = 3

        log file = /var/log/samba.log

        debug timestamp = yes

 

[webuser01]

        comment = webuser1 workspace

        path = /var/shared/webuser01

        browseable = yes

        read only = no

        guest ok = yes

        force user = www-data

        force group = www-data

        create mask = 0775

        directory mask = 0775

 

But when I try to access this share on a windows 7 machine, I got a
login box and every combination of username and password that I try
fails.

 

On the /var/log/samba.log :

 

[2013/10/24 11:37:56,  3]

Can you guys help me figure it out what the problem is!?

 

Thanks
